The Research on Dense Packing Concrete Mix Proportion
According to the postulation on dense packing of aggregates, the paper discusses the dense packing method of various aggregates and its coefficients, and offers the mix proportion design method of concrete. The research results indicate that using method of the mix proportion design based on the theory on dense packing of aggregates, aggregates can play a maximum role, especially the micro-aggregate effect of the fly ash, then the compactness of concrete is raised effectively, the quantity of cement is reduced and the endurance of concrete is improved.
