Blast furnace slag solid waste-based concrete and preparation process thereof
The invention relates to the technical field of concrete, and provides blast furnace slag solid waste based concrete and a preparation technology thereof.The blast furnace slag solid waste based concrete is prepared from, by mass, 25-30 parts of cement, 185-195 parts of blast furnace slag, 5-10 parts of silica powder, 3-8 parts of fly ash, 0.5-1 part of bentonite micro powder, 0.4-1 part of a water reducing agent, 15-20 parts of water, 0.5-2.5 parts of ferric chloride and 0.1-1.7 parts of carboxylic acid compounds containing sulfonic groups. Through the technical scheme, the problem of low compressive strength of concrete prepared from blast furnace slag in the prior art is solved.
本发明涉及混凝土技术领域，提出了一种高炉渣固废基混凝土及其制备工艺，一种高炉渣固废基混凝土，包括以下质量份的组分：水泥25~30份、高炉渣185~195份、硅微粉5~10份、粉煤灰3~8份、膨润土微粉0.5~1份、减水剂0.4~1份、水15~20份、氯化铁0.5~2.5份、含有磺酸基的羧酸类化合物0.1~1.7份。通过上述技术方案，解决了现有技术中的高炉渣制备的混凝土抗压强度低的问题。
