摘    要:抗压强度为30MPa的砼中,砼受压破坏时粗骨料是完整的没受到破坏。而高性能砼则由于砼强度比较高,砼破坏时粗骨料几乎完全断裂破坏。本文对不同品种的粗骨料在砼中的体积含量、最大粒径对砼强度的影响进行了试验,并根据试验结果得到了数学模型,用以评价不同品种粗骨料的性能

关 键 词:粗骨料  高性能砼  粗骨料体积含量  最大粒径  抗压强度

Abstract:In normal concrete with compressive strength about 30 MPa,the course aggregates have not been damaged when the concrete crushed by compressive test But for the high performance concrete(H P C),all of the coarse aggregates in concrete are crushed by the compressive test of concrete The experiments for the effect of the volume content and maximum size of different types of coarse aggregate on compressiv strength of concrete have been done According to the results of the test,the mathematical model is attended to evaluate the properties of the coarse aggregates
Keywords:Coarse aggregate  high performance concrete  volume content of coarse aggregate  maximum size of coarse aggregate  compressive strength
