Concrete with cement paste replaced by industrial solid waste silica fume and preparation method of concrete
The invention relates to concrete with cement paste replaced by industrial solid waste silica fume and a preparation method thereof, the concrete comprises the following components by weight: 216-240 parts of cement, 0-35.5 parts of common silica fume, 0-35.5 parts of high purity silica fume, 620 parts of sand, 1445 parts of stone, 1.20-1.26 parts of a superplasticizer, and 103.5-115 parts of water; the preparation method comprises the following steps: firstly, cleaning a double-horizontal-shaft concrete mixer, pre-mixing mortar with the same water-binder ratio, hanging the mortar on the inner wall of the mixer, and pouring out the residual mortar; the raw materials are weighed according to the mixing proportion, and then the stone, the sand, the cement, the common silica fume or the high-purity silica fume are sequentially added into a stirring machine to be stirred; finally, the water doped with the water reducing agent is uniformly poured into a stirrer to be stirred; the concrete prepared by replacing cement paste with the solid waste silica fume has the advantages that the mechanical property is obviously improved, and the internal compactness of the concrete is improved; the use amount of cement can be greatly reduced, and remarkable ecological benefits and economic benefits are achieved.
一种工业固废硅灰替代水泥浆体的混凝土及其制备方法，混凝土组成包括：按重量份数计，水泥216～240份，普通硅灰0～35.5份，高纯度硅灰0～35.5份，砂620份，石1445份，高效减水剂1.20～1.26份，水103.5～115份；制备方法是先将双卧轴混凝土搅拌机清洗干净，并且预拌水胶比相同的砂浆，对搅拌机内壁挂浆，将剩余料浆倒出；再根据配合比称量原材料，然后依次在搅拌机中加入石、砂、水泥、普通硅灰或高纯度硅灰进行搅拌；最后将掺有减水剂的水均匀倒入搅拌机中搅拌；固废硅灰替代水泥浆体制备的混凝土显著提高力学性能，改善混凝土内部密实度；还能大大节约水泥用量，具有显著的生态效益和经济效益。
