Ecological Illspring molybdenum tailing ultra-high performance concrete and preparation method thereof
The invention belongs to the field of ultra-high-performance concrete and particularly relates to ecological Illspring molybdenum tailing ultra-high-performance concrete and a preparation method thereof, in particular to ecological Illspring molybdenum tailing ultra-high-performance concrete and a preparation method of the ecological Illspring molybdenum tailing ultra-high-performance concrete. The invention aims to solve the problems that the performance of the existing molybdenum tailings used for preparing the ultra-high performance concrete is lower than that of the traditional ultra-high performance concrete, and the production place is polluted due to molybdenum tailings accumulation in the Ichun region. The concrete is composed of cement, silica fume, superfine fly ash microspheres, river sand, molybdenum tailings, a high efficiency water reducer, an antifoaming agent and water. The method comprises the following steps: mixing the cement, the silica fume, the superfine fly ash microspheres, the river sand and the molybdenum tailings, and pre-stirring; mixing the high-efficiency water reducing agent, the defoaming agent and the water, adding in twice, stirring, discharging, preparing a test piece, and curing. According to the invention, the molybdenum tailings accumulated in the Illspring region are used for replacing river sand and used for preparing the ultra-high performance concrete. The method has better compressive strength, greatly reduces the economic cost and improves the ecological effect.
一种生态型伊春钼尾矿超高性能混凝土及其制备方法，本发明属于超高性能混凝土领域，具体涉及一种生态型伊春钼尾矿超高性能混凝土及其制备方法。本发明目的是为了解决现有钼尾矿用于超高性能混凝土制备其性能低于传统超高性能混凝土，以及伊春地区钼尾矿堆积对产地造成的污染的问题。它由水泥、硅灰、超细粉煤灰微珠、河砂、钼尾矿、高效减水剂、消泡剂和水组成。方法：水泥、硅灰、超细粉煤灰微珠、河砂和钼尾矿混合，预搅拌；将高效减水剂、消泡剂和水混合后分两次加入搅拌，出料、制备试件、养护。本发明利用伊春地区堆积的钼尾矿取代河砂，用于超高性能混凝土的制备。不但具有较好的抗压强度，大幅度减少经济成本，提高生态效应。
