石粉作为碾压混凝土掺合料的试验研究

Research on limestone powder as mineral admixture in roller compacted concrete

通过对不同岩石的石粉作为碾压混凝土的掺合料配制碾压混凝土的力学性能、变形性能和耐久性能的测试,得出了石粉完全可以替代粉煤灰作为碾压混凝土的掺合料,配制出C9020P12F200的碾压混凝土。

Studied the mechanical property,volume stability and durability of roller compacted concrete which use limestone powder from different limestone as admixture.The results show that limestone powder can be used as a good substitute for fly ash which used in roller compacted concrete.The roller compacted concrete of C9020P12F200 was prepared successfully.
