Antifreeze agent with air entraining and filling effects, concrete and preparation and application methods of antifreeze agent and concrete
The invention discloses an antifreeze agent with air entraining and filling effects, concrete and preparation and application methods of the antifreeze agent and the concrete. The antifreeze agent comprises powder of the following raw material components: sodium carbonate, quartz, tricalcium silicate and calcium hydroxide, wherein the sodium carbonate and the calcium hydroxide form a coating structure taking the sodium carbonate as a core and the calcium hydroxide as a shell. In the anti-freezing agent, the sodium carbonate can generate carbon dioxide through hydrolysis reaction, micropores are generated in a concrete material, the calcium hydroxide can control the time of sodium carbonate reaction and hydrolysis and consume residual carbon dioxide in the micropores to prevent concrete carbonization, and the quartz powder can further fill generated pores with the size of more than micron. The anti-permeability of the material is maintained, so that the obtained anti-freezing agent has excellent anti-freezing and anti-permeability performance, and the performance can be kept stable for a long time.
本发明公开了一种具有引气填充效用的抗冻剂及混凝土和其制备与应用方法。所述抗冻剂包括以下原料组分的粉料：碳酸钠、石英、硅酸三钙和氢氧化钙，且其中碳酸钠和氢氧化钙形成以碳酸钠为核、氢氧化钙为壳的包覆结构。本发明的抗冻剂中，碳酸钠通过水解反应可产生二氧化碳，使混凝土材料中产生微孔隙，氢氧化钙可控制碳酸钠反生水解的时间并消耗微孔隙内的残余二氧化碳防止混凝土碳化，石英粉可进一步对产生的微米级以上的气孔进行填充，保持材料的抗渗透性，使所得抗冻剂具有优异的抗冻和抗渗透性能，且性能可长期保持稳定。
