Concrete reinforcing agent and preparation method thereof
The invention discloses a concrete reinforcing agent, and relates to the technical field of concrete production. A purpose of the invention is to solve the problem of easy water permeation caused by the existing concrete reinforcing agent. The concrete reinforcing agent comprises the following raw materials: ethylene glycol, isopropanol, a polyurethane emulsion, modified silica powder, hydrophilicfumed silica, modified silica powder, sodium sulfate, hydroxypropyl methyl cellulose, ethylene oxide, glycerin, sodium metasilicate pentahydrate, a retarder, an antifoaming agent, sodium dodecyl benzene sulfonate and calcium lignosulphonate. The invention also discloses a preparation method of the concrete reinforcing agent. According to the invention, sodium sulfate is used as a water reducing agent, so that the strength of a cement base can be rapidly improved; the concrete reinforcing agent prepared by taking the hydrophilic fumed silica as the raw material is insensitive to the mud content in machine-made sand, and cannot affect the strength of concrete by the increase of the mud content; and the compressive strength of the concrete is further improved by adding calcium lignosulphonate, and the concrete reinforcing agent has a wide market prospect.
本发明公开了一种混凝土增强剂，涉及混凝土生产技术领域，为了解决现有混凝土增强剂带来的水分易渗透的问题，包括以下原料：乙二醇、异丙醇、聚氨酯乳液、改性硅石粉、亲水性气相白炭黑、改性硅石粉、硫酸钠、羟丙基甲基纤维素、环氧乙烷、甘油、五水偏硅酸钠、缓凝剂、消泡剂、十二烷基苯磺酸钠、木质素磺酸钙，本发明还公开了所述混凝土增强剂的制备方法，本发明制备的混凝土增强剂用硫酸钠作为减水剂，可以使水泥基的强度得到快速提升；亲水性气相白炭黑作为原料制备获得的混凝土增强剂，对机制砂中的含泥量不敏感，不会因含泥量增大而影响混凝土强度，通过加入木质素磺酸钙，进一步提高了混凝土的抗压强度，具有广阔的市场前景。
