Molybdenum slag doped active powder concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to reactive powder concrete prepared by doping molybdenum slag and a preparation method of the reactive powder concrete. The active powder concrete comprises the following raw materials in parts by weight: 400-450 parts of cement; 100 to 120 parts of silica fume; 440 to 500 parts of quartz sand; 50 to 170 parts of molybdenum slag; 0 to 170 parts of quartz powder; 65 to 78 parts of steel fiber; 4-9 parts of a water reducing agent; and 70-90 parts of water. The method not only effectively solves the problem that too much molybdenum slag is accumulated to cause adverse effects on the environment, but also reduces the RPC cost to a certain extent. On the basis, high RPC strength can still be maintained, and the requirements of actual engineering for high-strength and high-performance concrete are met.
本发明属于混凝土技术领域，尤其涉及一种掺入钼渣制备活性粉末混凝土及其制备方法。一种掺入钼渣的活性粉末混凝土，包括以下重量份原料：水泥400～450份；硅灰100～120份；石英砂440～500份；钼渣50～170份；石英粉0～170份；钢纤维65～78份；减水剂4～9份；水70～90份。本发明不仅有效解决了钼渣堆积过多对环境造成不利影响，同时一定程度上减少RPC成本。在此基础上仍能维持RPC较高强度，满足实际工程对高强、高性能混凝土的需求。
