RPC cover plate for subway evacuation platform and preparation method of RPC cover plate
The invention discloses an RPC cover plate for a subway evacuation platform and a preparation method of the RPC cover plate. The RPC cover plate comprises the raw materials in parts by weight: 500 to 1000 parts of cement, 250 to 600 parts of mineral admixture, 700 to 1200 parts of quartz sand, 50 to 400 parts of modified wollastonite powder, 10 to 30 parts of polyformaldehyde fibers, 10 to 50 parts of glass fibers, 0.2 to 2 parts of organic fibers, 10 to 40 parts of a polycarboxylic acid type water reducing agent, 0.2 to 2 parts of a brightening agent and 150 to 250 parts of water. Through the synergistic toughening effect of the wollastonite and the multi-scale hybrid fibers of the steel fibers, the expansion of ultra-high-performance macroscopic crack powder and the generation of micro cracks can be inhibited, and the toughness and the volume stability of the concrete are greatly improved. Meanwhile, the wollastonite powder is high in color whiteness, and the color and appearance of the concrete can be improved.
本发明公开了一种用于地铁疏散平台的RPC盖板及其制备方法，所述RPC盖板的原料按重量份数计包括水泥500～1000份、矿物掺和料250～600份、石英砂700～1200份、改性硅灰石粉50～400份、聚甲醛纤维10～30份、玻璃纤维10～50份，有机纤维0.2～2份，聚羧酸系减水剂10～40份、光亮剂0.2～2份以及水150～250份。本发明通过硅灰石与钢纤维的多尺度混杂纤维协同增韧作用，能够抑制超高性能的宏观裂缝粉扩展和微观裂纹的产生，大幅提高混凝土的韧性和体积稳定性。同时硅灰石粉颜色白度高，能够改善混凝土的颜色和外观。
