Good morning everyone!It is my pleasure to give a presentation here.As a student whose major is safety engineering, I’d like to introduce a safety evaluation method today, the LEC evaluation.As the PPT shows, my presentation is mainly divided into three parts.Firstly, let me introduce LEC briefly.Maybe some of you have learned about LEC in college, it is used to assess the degree of danger when people work in potentially dangerous environment.It is a half-quantitative safety evaluation method which classifies one certain system and determine if the system is safe enough.Then, what does each letter mean?D means danger, it shows how dangerous the system is.L means likelihood, it shows the possibility of the accident.E means the extent of exposure, it shows that how often do workers work in dangerous environment.C means consequence, it shows the severity of accidents.Here ,it is a chart, each part is divided into several levels.Take the likelihood as an example, it has seven levels, the points range from 0.1 to 10 as the possibility rising.And if the score of D is over 320,itmeans this system is extremely dangerous and cannot continue operating.Through LEC evaluation, we can make sure if we need to rectify and reform the workplace, so that we can take some measures for safety to avoid accidents.It is easy to use and it is feasible for the situation which is lack of specific evaluation models or data.The LEC method is widely used in various fields, such as aircraft industry, railway industry, metallurgic industry, coal-mining industry and so on.The usage of LEC doesn’t have many differences.Firstly, we should select the evaluation unit, thenidentify the main danger in the unit.Next , we need to evaluate the danger by using that chart and get a conclusion.

On the International Day of United Nations peacekeepers, we honour the sacrifices of the men and women who lost their lives while serving under the UN flag.This year's commemoration is a somber one.The past 14 months have been especially deadly for UN peacekeeping.Ambushes in Darfur...Terrorism in Kabul...And a plane crash in Haiti...These were among the tragedies that struck peacekeeping last year, killing 121 people.That toll was nearly matched in a few seconds with the devastating earthquake that struck Haiti last January.The United Nations Stabilization Mission in Haiti lost 96 peacekeepers--the biggest single loss of life in peacekeeping history.But that dark day also became one of our finest hours, as the men and women of MINUSTAH set aside their own trauma, got the mission quickly back on its feet, and helped the people of Haiti cope with the horrific aftermath.As we honour such moving displays of courage and dedication, we also pay tribute to the more than 122,000 military, police and civilian personnel who serve with distinction in our operations across the world.Their efforts directly help millions of people...By providing security and promoting reconciliation...By clearing land-mines and demobilizing combatants...By strengthening institutions and the rule of law...By delivering aid and repatriating refugees and displaced persons

By supporting democratic elections, reforming the security sector...and so much more.peacekeeping is an indispensable part of the UN’s work for a better world.Let us give it the support it needs to succeed.

Freeze–thaw cycle test and damage mechanics models of

alkali-activated slag concrete＇＇＇＇

Thank you for your invitation and warm hospitality.“Freeze–thaw cycle test and damage mechanics models of alkali-activated slag concrete” I would like to thank Professor Cui ,for inviting me to deliver this“Freeze-thaw cycle test and damage mechanics models of alkali-activated slag concrete”.Theplentiful studies on a new green binding material—alkali-activated concrete.The effect of freeze-thaw cycles on in concrete was studied by experiment.，I shall explore a possible agenda for analysis to enable understanding of the alkali-activated slag concrete.“new green binding material—alkali-activated cement”the introduction of Freeze–thaw cycle test and damage mechanics models of alkali-activated slag concrete.Now let's look at the ppt In recent years, there are plentiful studies on a new green binding material—alkali-activated cement, it can be prepared by wastes containing kaolinite(原文introduction第一句)The binding materials with three-dimensional network structure are yield by shrinking and polymerization reaction.With the arriving of low carbon economy time, international governments attach more importance to energy saving, emission reducing and cycled economics.(原文第二段)a genuine low carbon cement.（ppt第3頁(yè)）–I'd like to talk is the materialswe can see clear that the Slag used in this study was metallurgy blast furnace slag, was supplied by Jiangxi Building Materials Plant, PR China, its specific surface is 410 m2/kg.chemical compositions of slag are listed in.（ppt第4頁(yè)）

NaOH and Na2SiO3 sodium silicate multiplex solution was used as alkali activator, module of sodium silicate is 3.34.Sand with fineness modulus of 2.78 was used as fine aggregate.Limestone were used as crushed rock aggregate(5–20 mm:20–40 mm = 45:55).(引用原文Materials第二段結(jié)論)Mix proportion and specimen preparation ,.Mix proportion and specimen preparation.Mix proportion, workability and compressive strength at 28 d of ASC are listed in.It was prepared by a single decubital axis compellent beater with content of 60 L.the samples were demoulded and cured

under scheduled regimes.Thirty samples were tested for freeze–thaw cycle tests.Table 1.Mix proportion, workability and strength of ASC(引用原文第二部分第二小點(diǎn))（ppt第5頁(yè)）The Freeze–thaw resistance was tested according to ASTM C666 and GB/T 50082-2009 “Standard for test methods of long-term performance and durability of ordinary concrete”.Six samples of each batch were tested, the average value of 6 samples was served as the finial freeze–thaw resistance.Mass and dynamic elasticity modulus were tested once after an interval of 25 times cycles, maximal cycle times(when relative dynamic elasticity modulus was 60% and percentage of mass loss was 5% at lowest)can denote freeze–thaw resistance of ASC.TDR-16V computer controlled concrete fast freeze–thaw cycle testing machine and DT-10W dynamic elasticity modulus testing machine were used to conduct the tests.(原文2.3 /ppt第6頁(yè))

–thaw resistance mechanism of ASC 2.Freeze–thaw resistance durability of ASC(ppt 第7頁(yè))

Results of fast freeze–thaw cycle tests of ASC are listed in Table 3.As can be seen:(1)With the increase of freeze–thaw cycle times, relative dynamic elasticity modulus of ASC are descending slowly, this shows excellent ductility, relative dynamic elasticity modulus of A1–A5 are all about 90% at 300 times cycle（ppt第8頁(yè)）(2)It is improper to set mass loss of ASC as the evaluation index of freeze–thaw destroy, because mass loss of A1–A5 vary indistinctively in the progress of freeze–thaw, it cannot reflect the destroy degree of concrete exactly, thus it is improper to use it to test and evaluate the freeze–thaw damage of ASC(which is shown in Fig.1).（ppt第9頁(yè)）

The first is ASC used industrial waste – slag as raw materials, and it had excellent freeze–thaw resistance with frost-resisting grade of F300 at lowest, relative dynamic elasticity modulus were about 90% after 300 times freeze–thaw cycles, it also had little mass loss, surface freeze–thaw damage layers were very thin, which can effectively restrain freeze–thaw damage of concrete from worsening.(ppt第10頁(yè))The second is Different from freeze–thaw cycle damage models of PC, dynamic elasticity modulus attenuation models were superior to accumulative freeze–thaw damage models, and power function models were superior to exponential function models with better precision and relativity.（ppt第10頁(yè)）

Thank you very much for the privilege of presenting this paper

第四篇：國(guó)際會(huì)議作報(bào)告英語(yǔ)發(fā)言稿

Thank you, prof.….My name is …..I’m from …..I am very pleased to be here to join this forum.The topic of my presentation is properties of rapid construction materials for soil pavement of field airfield.As is shown in the picture, the main parts of my research are about soil pavement.My presentation will include these four parts:

First, some background information about this research;second, the main work we have done;third, some conclusions we have got and the last: innovation and presentation of our published papers.Why I choose this item? I think it can be illustrated from the following four parts.First, the existing quantity of airfields is still not sufficient and the airfields have many shortcomings especially in war time.Second, the complementary facilities, such as highway runways are far less than airfields, however, have more weakness.Third, a certain amount of field airfield is quite necessary considering some emergencies such as rescue and disaster relief.Forth, the field airfield can fill the void of airfield and they can be combined to be airfield network.The meaning and aim of this research contains three parts.Fast, convenient and validity, fast means the field airfield must be constructed as fast as possible, convenient means the construction should need the minimum equipment, labor and materials considering the actual construction condition, validity means the constructed airfield is able to support the operation of given aircraft in specifically time.Just like many other territories, the situation of the research is that the U.S.Army takes advanced line.The U.S.Army declares that they can reach to anywhere on the earth in 96 hours, the most important method for force projection is though aircraft, thus rapid construction of pavement is the key problem for rapid force transportation.The main work we have done can be summarized as four parts, materials choosing, scheme making, mechanical properties research and water-stable properties research.We choose two kinds of soils, which are got from Xi’an, Shanxi province and Jiuquan, Gansu province separately.The sand from Ba River was considerate to investigate the influence of sand to the properties of stabilized soil.The chosen three kinds of powders are cement, lime and new-type stabilizer developed by Chang’an University.The principles in considering the function of 4 kings of fibers are referring different length, type and mixing them.On account of the time, I will make a brief description about the experiment scheme.In summary, three parts were proposed to distinguish the affecting factors in making experiment scheme.They are powder control, fiber control and other factors.Taking powder control for example, the dosage of cement is respectively 6%, 8% and 10% when the soil is stabilized only by cement, while the dosage of cement decrease to 3%, 5% and 7% when the lime is addicted to stabilized soil.The following two factors are stabilizer and sand.Six kinds of experiments were performed to investigate the influence of above factors to the mechanical properties of stabilized soil.The aim of compaction test is to find the maximum dry density and optimum moisture content.The aim of compression strength test is to determine the optimum dosage of cement, lime, powder stabilizer and fiber, meanwhile evaluating the performance of stabilized soil.The aim of splitting tension strength test is similar to compression strength test, the left picture is sample stabilized by cement, while the right picture is the sample stabilized by fiber and cement.The direct sheer is another important parameter in geotechnical engineering.It influences the foundation bearing capacity and many other properties especially for soil base and base course.The left picture shows the course of making sample and the right picture shows the test process.The CBR test and rebound modulus test are referenced from highway test specification to evaluating the comprehensive capacities of each structure level of the pavement.For both the two tests, the left picture shows the course of making sample and the right picture shows the test process.What should be noted is that the number of sample is at least 6, the last result is the average value of these date got from test after eliminating the bad results.Four kinds of experiments were performed to investigate the influence of above factors to the water-stable properties of stabilized soil.The scouring test is not the stated experiment in current specification.It is performed by us through looking up large quantity of interrelated literature, and two different ways to carry out.The left picture shows the method of vibration table and the right picture shows the method of fatigue test instrument.Penetrant test refers to the experiment in relating concrete specification.The left picture shows the process of saturation, the right picture shows the test process.Cantabria test and other tests are all original experiments;they are used in stabilized soil for first time, here I will not develop my narrative.As regards the innovation, I think it throughout the whole research, including materials choosing, scheme making, mechanical and water-stable experiments.I think it can be drawled from the following keywords, such as soil choosing, sand, powders, fibers, and so on.Three main parts can be summarized.First, selecting two kinds of soils, three kinds of powders, several combinations;second, several kinds of fibers, different length and admixture;third, comprehensive experiments, test method and test instrument.
