Abstract
Description
technical field
[0001] The invention relates to the technical field of performance prediction of permeable concrete, in particular to a performance prediction method and system of permeable concrete based on mesoscopic model reconstruction. Background technique
[0002] Permeable concrete is composed of coarse aggregate, coarse aggregate cement-based coating and pores. The performance of pervious concrete depends directly on the properties of coarse aggregate and coarse aggregate cement-based coating. Since there is only a small amount of cement matrix in pervious concrete and it is often formed by pressure, the coarse aggregate in its structure can be considered to be in a tightly packed state. For the selected coarse aggregate, the structure and performance of the tightly packed state are known, so the pore structure can be changed by artificially designing the performance and distribution of the cement base, so as to realize the reconstruction of the pervious concrete mo...
