Large-volume shrinkage-compensating impervious concrete for garbage pools and leachate pools
The invention provides large-volume shrinkage-compensating impervious concrete for a garbage pool and a leachate pool. The large-volume shrinkage-compensating impervious concrete is prepared from the following raw materials: ordinary silicate 425 cement, fly ash microspheres, slag powder, an expanding agent, modified basalt fibers, quartz sand, limestone, water and an organosilane modified water reducing agent. The large-volume shrinkage-compensating anti-seepage concrete is mainly used in large-volume concrete structures with high anti-seepage and anti-crack requirements such as garbage pools and leachate pools, and the large-volume shrinkage-compensating anti-seepage concrete reasonably utilizes large-dosage composite auxiliary cementing materials such as the fly ash microbeads and the slag powder as well as three MgO expanding agents with different activities, so that the large-volume shrinkage-compensating anti-seepage concrete has high anti-seepage and anti-crack requirements; the purposes of low concrete temperature rise, small temperature shrinkage, good shrinkage compensation effect and high permeability resistance are achieved, and the concrete is specially used in mass concrete structures with high anti-seepage and anti-crack requirements such as garbage pools and leachate pools.
本发明提供一种用于垃圾池及渗沥液池的大体积补偿收缩抗渗混凝土，包括以下原料：普通硅酸盐425水泥，粉煤灰微珠，矿渣粉，膨胀剂，改性玄武岩纤维，石英砂，石灰石，水及有机硅烷改性减水剂。本发明中大体积补偿收缩抗渗混凝土主要用于垃圾池、渗沥液池等防渗抗裂要求高的大体积混凝土结构中，由于其合理利用了大掺量复合辅助性胶凝材料如粉煤灰微珠与矿渣粉以及三种不同活性的MgO膨胀剂，实现了混凝土温升低、温度收缩小、补偿收缩效果好、抗渗透性高的目的，专用于在垃圾池及渗沥液池等防渗抗裂要求高的大体积混凝土结构中。
