Concrete waterproof compacting agent and preparation method thereof
The invention discloses a concrete waterproof compacting agent and a preparation method thereof. The compacting agent comprises 3%-5% ofglycerol; 10%-12% of sodium thiosulfate; 1%-1.5% of sodium hydroxide; 2%-3.5% of amino triethanol; 1%-1.5% of fatty alcohol-polyoxyethylene ether; 0.5-1% of a mixture of a defoaming agent and a waterproof agent; 8%-10% of methyl sodium silicate; and 8%-10% of hydrated sodium thiosulfate. According to the present invention, the sodium thiosulfate is adopted to replace an early strength agent, such that the early strength of the concrete can be effectively improved, hydration of the cement can be promoted, the pore structure of the hydration product can be improved, the concrete tends to be dense, the concrete can be used in the environment with the low air temperature, the concrete can be applied in a wider range, the defoaming agent is added into the waterproof agent, so that bubbles in a system are effectively reduced, the heat-conducting property and the adhesive property of a product are favorably improved, and the problem of cracking of the concrete caused at an early stage is solved by utilizing the characteristics of sodium thiosulfate, and the purposes of enhancing the compactness of the concrete, improving the strength of the concrete, controlling cracking, pitted surfaces and water molecules to form a hydrophobic effect, and being water resistant and impermeable are achieved.
本发明公开了混凝土防水密实剂及其制备方法，包括甘油3％‑5％；硫代硫酸钠10％‑12％；氢氧化钠1％‑1.5％；氨基三乙醇2％‑3.5％；脂肪醇聚氧乙烯醚1％‑1.5％；消泡剂与防水剂混合物0.5‑1％；甲基硅酸钠8％‑10％；水化硫铝酸钙8％‑10％，本发明的有益效果如下：本发明用硫代硫酸钠代替早强剂，可以有效地提高混凝土的早期强度，能促进水泥的水化，可以改善水化产物孔结构，使混凝土趋于密实，能在空气温度较低的环境中使用，提高了混凝土的适用广泛性，在防水剂中加入消泡剂，有效减少了体系内的气泡，有助提升产品的导热性能与粘结性能，利用硫代硫酸钠的特性，解决了混凝土早期引起的开裂问题，达到增强混凝土密实性、提高混凝土强度、控制开裂、麻面与水分子形成憎水效应，防水抗渗性的目的。
