混凝土制品质量控制问题包括预测水灰比(B/Ц)不同的混凝土在时间(τ)内的强度(Rσ)增长情况、即求出关系式Rσ=Rσ(τ,B/Ц)。本文对这一问题是在考察混凝土强度与水泥石孔隙率(П)的关系,和顾及到水泥水化力学规律的基础上解决的。把组合材料作为在结构上有一定程度紊乱性的体系加以研究可以得出表示多孔物体 The quality control problem of concrete products includes the prediction of the increase in strength (Rσ) of concrete with different water/cement ratios (B/Ц) over time (τ), ie, the relationship Rσ=Rσ(τ,B/Ц). This article addresses this issue by examining the relationship between concrete strength and cement stone porosity (P), and taking into account the laws of cement hydration mechanics. The study of composite materials as a system with a certain degree of structural disorder can be expressed as porous objects.
