Fine aggregate concrete additive and preparation method thereof
The invention provides a fine aggregate concrete additive and a preparation method thereof, and belongs to the technical field of building materials. The fine aggregate concrete additive disclosed by the invention is prepared from the following components in parts by mass: 25 to 30 parts of sodium lignin sulfonate; 20-25 parts of a sulfamate high-efficiency water reducing agent; 10 to 15 parts of sodium gluconate; and 40-45 parts of calcium nitrite. According to the fine aggregate concrete additive provided by the invention, high-strength ultrathin concrete slabs can be produced from fine aggregate concrete, and the service life of the concrete slabs can be prolonged and the anti-freezing performance of the concrete slabs can be improved by adding the fine aggregate concrete additive provided by the invention. The ultrathin concrete plate produced by the fine aggregate concrete additive can replace some traditional steel or biomass plates in the current construction industry, and is beneficial to saving materials and reducing carbon emission.
本发明提供了一种细石混凝土添加剂及其制备方法，属于建筑材料技术领域。本发明的细石混凝土添加剂由包括以下质量份数的组分组成：木质素磺酸钠25～30份；氨基磺酸盐高效减水剂20～25份；葡萄糖酸钠10～15份；亚硝酸钙40～45份。本发明提供的细石混凝土添加剂可使细石混凝土生产高强度超薄混凝土板，且添加本发明的细石混凝土添加剂可延长混凝土板的使用寿命，增加混凝土板的防冻性能。本发明细石混凝土添加剂生产的超薄混凝土板可替代目前建筑业一些传统钢制或生物质板的应用，有利于节约材料，减少碳排放。
