裂缝控制技术在防辐射大体积混凝土中的应用

水泥在水化过程中产生大量的热量，使混凝土内部温度升高。当混凝土内部与表面的温差过大时，就会产生温度应力，当这种温度应力超过混凝士内外的约束力时，就会产生裂缝，影响混凝土的正常使用，本文介绍了几种控制裂缝的方法。

Application of fracture controlling technology in anti-radiation massive volume concrete

Large amount of heat value can be produced during cement hydration, and makes the concrete inside temperature rise, which can produce temperature stress when the difference between the surface and inside is too large, and in turn, the fracture could be produced in the concrete body when the stress exceeds the concrete body's constraint force;and finally, influences its normal usable function. The paper introduces several fracture controlling methods.
