水泥混凝土高强化与强度尺寸效应

Improvement of Strength and Size Effect on Strength of Concrete

通过试验研究和数值分析（考虑比较特殊的情况）证实即使实验室尺度上混凝土强度很高，但如果其脆性很大。

It is shown that a highstrength concrete with high brittleness in laboratory scale displays lower strength than a normal concrete with low brittleness in larger scale, because strength of highstrength concrete decreases quickly with scale increasing. This possibility has been proved based on experimental research and numerical analysis.
