the mass concrete

During the mass concrete construction in bridge structure, the cement hydration heat is easy to cause surface cracking.

大体积混凝土在桥梁施工过程中，由于水泥水化热容易引起表面裂缝。

Releasing steam heat from the mass concrete structures while solidifying leads to produce the temperature change and contraction.

大体积混凝土在固化过程释放的水化热会产生较大的温度变化和收缩作用。

The problem of thermal stress and a need for temperature control in the mass concrete construction also occur in the roller compacted concrete dams(RCCD).

大体积混凝土的温度应力问题与温度控制要求在碾压混凝土坝中同样存在。
