Mica modifier, application of mica modifier, concrete and preparation method of concrete
The invention relates to the technical field of building materials, and particularly discloses a mica modifier and application thereof, and concrete and a preparation method thereof, the mica modifier comprises the following components: a polyoxyethylene surfactant, polyethylene glycol and lauryl sodium sulfate. The concrete comprises the following components in parts by weight: 290-330 kg/m < 3 > of low-heat Portland cement, 738-765 kg/m < 3 > of fine sand, 1200-1350 kg/m < 3 > of 5-20 mm aggregate, 55-85 kg/m < 3 > of water and 2-4 kg/m < 3 > of mica modifier. The mica modifier can be directly added into a building material containing mica to modify the mica, the interface bonding force of fine aggregate mica and set cement is improved, and the mechanical property and the anti-freezing property of concrete prepared by adding the mica modifier are improved. According to the invention, the tedious process of manually removing and magnetically separating mica sheets in the current engineering can be solved, and the adverse effect of mica on the concrete can be solved by directly adding the modified material into the concrete.
本发明涉及建筑材料技术领域，具体公开了一种云母改性剂及其应用和混凝土及其制备方法，云母改性剂，包括以下组分：聚氧乙烯型表面活性剂、聚乙二醇和十二烷基硫酸钠。混凝土包括以下重量份组分：低热硅酸盐水泥290～330kg/m3、细砂738～765、5～20mm骨料1200～1350kg/m3、水55～85kg/m3和云母改性剂2～4kg/m3。该云母改性剂可直接添加含有云母的建筑材料中，对云母进行改性，提高细骨料云母与水泥石界面结合力，且添加有云母改性剂制备的混凝土的力学性能和抗冻性能均有所提升，即本发明能够解决目前工程上采用人工清除、磁选清除云母片的繁琐工艺，直接在混凝土中添加改性材料就可以解决云母对混凝土带来的不利影响。
