Concrete waterproof compact shrinkage reducing agent and preparation method thereof
The invention is suitable for the technical field of concrete shrinkage reducing agents, and provides a concrete waterproof compact shrinkage reducing agent and a preparation method thereof, and the concrete waterproof compact shrinkage reducing agent comprises the following raw material components by mass: 5-8 parts of nano silica sol, 0.1-1 part of volcanic ash, 0.1-1 part of zeolite powder, 18-26 parts of sodium silicate, 0.5-2 parts of sodium carbonate, 5-10 parts of nano alumina, and 40-60 parts of water. According to the concrete waterproof compact shrinkage reducing agent and the preparation method thereof, the nanometer silica sol, the volcanic ash, the zeolite powder, the sodium carbonate, the sodium silicate, the nanometer aluminum oxide and the water are used as raw materials and are properly proportioned to prepare the concrete waterproof compact shrinkage reducing agent, and the obtained concrete waterproof compact shrinkage reducing agent is used in concrete, so that the concrete waterproof compact shrinkage reducing agent has a good waterproof effect. The anti-permeability performance can be remarkably improved, early shrinkage of concrete is greatly reduced, concrete cracking is prevented, water permeation is effectively prevented, and meanwhile the concrete strength can be remarkably improved.
本发明适用于混凝土减缩剂技术领域，提供了一种混凝土防水密实减缩剂及其制备方法，以质量份数计，各原料组分及含量如下：纳米硅溶胶5‑8份、火山灰0.1‑1份、沸石粉0.1‑1份、硅酸钠18‑26份、碳酸钠0.5‑2份、纳米氧化铝5‑10份、水40‑60份，本发明提供的一种混凝土防水密实减缩剂及其制备方法，通过以纳米硅溶胶、火山灰、沸石粉、碳酸钠、硅酸钠、纳米氧化铝、水为原料，并进行适当配比，制得混凝土防水密实减缩剂，将得到的混凝土防水密实减缩剂用于混凝土中，能够显著提高抗渗性，大大减少混凝土早期收缩，防止混凝土开裂，有效阻止水分渗透，同时还能显著提高混凝土强度。
