Method for curing reinforced concrete
The invention relates to the technical field of concrete processes, and provides a method for curing reinforced concrete, which comprises the following steps: mixing reinforcing steel bars and concrete for forming to obtain reinforced concrete; performing pre-curing treatment on the reinforced concrete, and then placing the material in gas containing carbon dioxide to be subjected to carbonization treatment; wherein the conditions of the pre-curing treatment are as follows: the relative humidity range is 20-80%, the temperature range is 5-60 DEG C, and the wind speed range is 0-5m/s; the volume fraction of carbon dioxide in the gas containing carbon dioxide is 20%-100%, and the gas pressure is 1-10 bar. The reinforced concrete has high early strength and high carbon dioxide absorptivity through special pre-curing treatment in the early stage, so that the carbonization depth and permeability coefficient are controllable during carbonization curing, the corrosion risk of steel bars in the cured reinforced concrete is low, and the application prospect is very good.
本申请涉及混凝土工艺技术领域，提供了一种钢筋混凝土的养护方法，包括如下步骤：将钢筋与混凝土混合成型，得到钢筋混凝土；将所述钢筋混凝土进行预养处理，然后置于含二氧化碳的气体中进行碳化处理；其中，所述预养处理的条件包括：相对湿度范围为20％～80％，温度范围为5℃～60℃，风速范围为0～5m/s；所述含二氧化碳的气体中二氧化碳体积分数为20％～100％，气体压力为1‑10bar。本申请通过前期特有的预养处理，使得钢筋混凝土具有高早期强度和高二氧化碳吸收率，因此碳化养护时碳化深度和渗透系数可控，这样养护后的钢筋混凝土中钢筋锈蚀风险低，具有很好的应用前景。
