Research On Influence Of The Performance Of The Road Cement Concrete In Cement Technology Character

Cement is one of important raw material of road cement concrete , the road surface swiftness and violence develops in recent years with the cement concrete, correct cement quality the important approach requiring that the technology character also, more and more high , raising cement is that the concrete road uses a function optimize a road.The technology character in the past to cement uses the function effect research to road cement concrete road , is inclined to aspect such as building , irrigation works mostly, relatively, the speciality research specifically for road concrete is deficient in, and is short of a systematicness. Therefore,it is very necessary to carry out research on influence of the performance of the road cement concrete in cement technology character.At home and abroad on the status and background of the project, have In-depth analysised the influence of the performance of the road cement concrete in cement technology character, which contained standard consistency water requirement , cement setting time , cement pellet group characteristic (specific surface area , pellet distribution , 80 & micro; M sifts spare time) , flow degree , chemistry composition , volume stability , intensity , deformation and lasting quality etc.,and defined the nature of the characterization of these technologies in the road and concrete parameters of the role played by. After analysis, the choice of concrete roads and sensitive performance of the relative lack of focus on the cement for research.By the interior experiment and theoretical analysis, effect having studied the cement flowing deformation character stirs and mixes the road concrete job's face to face newly; Have analysed an impact of cement chemistry group and project character over road concrete; Have made use of the Mastersizer 2000 laser diffraction grading analysis instrument admeasurement to be unlike cement pellet grading , have transported the theory making use of gray system, priority base having studied the cement pellet scatters to stirring and mixing cement newly material and hardening cement base material the road uses the function effect , and have defineded the the correlation between The cement pellet scatters and the concrete road performance.the pellet recommending out the cement fitting in with in different climate subarea thereby scatters.This study was a state west of traffic projects, "composed of cement concrete road design," component "of raw materials technical nature of the impact of concrete roads," the study, research results not only for the raw materials of cement concrete road material, design and construction of a certain control Guiding significance, but also for the improvement of relevant norms provide the basic data.
