RESEARCH ON THE APPLICATION OF FULLY GRADED PARTICLE CURVES IN CONCRETE
Generally,based on national standards and empirical methods of coarse ore,the design of concrete mix proportions only yields one ordinary concrete product. To verify the importance of the particle size distribution curve,Fuller curve and Bolomey curve models are used to fit the screening results of sand and stone aggregates. The work-ability,envelopment,and strength data of C30 concrete prepared using the curves of the two models are compared,and it is concluded that the best density curve fitted based on Fuller curve and Bolomey curve using the same raw material is basically consistent.
