混凝土的养护就是给混凝上以足分的湿度与适当的温度,使混凝土处于不受有害应力影响。本来混凝土拌合物中所含的水分已足够水泥水化之用,但由于正常情况下空气相对湿度较低,混凝土内的水分会因表面蒸发而逐渐脱水,产生收缩裂缝,同时失水太多导致的干燥还会阻滞混凝 The curing of concrete is to give adequate humidity and proper temperature to the concrete, so that the concrete is not affected by harmful stress. The moisture contained in the concrete mixture is already sufficient for hydration of cement, but due to the relatively low relative humidity of the air under normal conditions, the moisture in the concrete will gradually dehydrate due to surface evaporation, causing shrinkage cracks and too much water loss. The resulting drying will also retard coagulation
