1 混凝土裂缝产生的原因混凝土在凝结硬化过程中,水泥水化反应产生的水化热会使混凝土温度升高。对于厚大体积混凝土,由于散热条件差,产生大量的水化热积蓄在混凝土块体内部,从而使其明显升温,混凝土温度的变化,会使混凝土产生温度变形。若此变形受到约束,必将产生温度应力。如果此应力为拉应力,且超过混凝土的抗拉强度时,混凝土就会产生温度裂缝。 A concrete cracks Causes Concrete condensation hardening process, the cement hydration reaction hydration heat will make the concrete temperature. For thick mass concrete, due to poor cooling conditions, a large amount of hydration heat accumulates inside the concrete block, making it significantly warmed, concrete temperature changes, will produce concrete temperature deformation. If this deformation is constrained, it is bound to produce temperature stress. If this stress is tensile, and exceeds the tensile strength of concrete, the concrete will produce temperature cracks.
