混凝土早期裂缝形成的判定

Estimation for early crack of concrete

从弹性力学的角度分析了混凝土早期裂缝形成的影响因素,定量计算弹性力学模型中水泥砂浆及骨料的应力应变,并判断早期裂缝产生的原因及位置,用细观力学方法计算各相应变,从而建立了判断早期裂缝的依据。

Analysis influence factors of concrete early crack by elastic mechanic method, calculate stress and strain of concrete mortar an gravel, estimate the reason of early crack and crack position,calculate strain of each component,based the estimation of concrete early crack.
