Self-compacting concrete with high fluidity, not segregation , uniformity and stability , pouring relies on its own weight flow , without vibrated to achieve dense , high-performance concrete . Its main features are: no manual vibrators , relying on weight populate the template dense , adapted to the reinforcement denser concrete pouring , can significantly reduce noise pollution, save labor , while the self-compacting concrete must be added to a large number of coal ash, slag powder mineral admixtures , is conducive to industrial waste utilization and environmental protection. This topic from the use of the Xinjiang region preparation of raw materials self-compacting concrete and its application in rockfill concrete application, the first choice of local raw materials made ??admixtures and cement, fly ash compatibility test, designed on the basis of self- compacting concrete orthogonal test , assessment of the admixture content , water-cement ratio, sand ratio , fly ash four factors on self-compacting concrete performance and mechanical properties of the order , and then use SPSS for self-compacting concrete mix likened to a multiple linear regression analysis of each assessment indicators regression equation . Finally , relying on Railway 21 Bureau , Xinjiang University , Tsinghua University, a collaborative project \research . Finally got the Xinjiang region of various factors on the self-compacting concrete performance and strength of the order of draw Xinjiang region of raw materials suitable for self-compacting concrete and rubble concrete preparation, demonstrated with pebbles as heaps of stone rubble concrete with good mechanical properties and engineering application value.
