Compression-resistant concrete containing solid wastes and preparation process of compression-resistant concrete
The invention relates to the technical field of concrete, and provides compressive concrete containing solid wastes and a preparation process of the compressive concrete. The invention discloses compressive concrete containing solid wastes. The compressive concrete is prepared from the following components in parts by mass: 25-30 parts of cement, 75-80 parts of gravel, 72-78 parts of sand, 15-25 parts of modified fly ash, 5-10 parts of mineral powder, 2-5 parts of fibers, 0.5-1 part of a water reducing agent and 15-20 parts of water, the modified fly ash is fly ash modified by polyacrylamide and sodium 3, 3 '-dithiodipropane sulfonate. Through the technical scheme, the problem of low compressive strength of concrete prepared from fly ash in the prior art is solved.
本发明涉及混凝土技术领域，提出了一种含固体废弃物的抗压混凝土及其制备工艺。一种含固体废弃物的抗压混凝土，包括以下质量份的组分：水泥25~30份、碎石75~80份、砂72~78份、改性粉煤灰15~25份、矿粉5~10份、纤维2~5份、减水剂0.5~1份、水15~20份；改性粉煤灰为经聚丙烯酰胺和聚二硫二丙烷磺酸钠改性的粉煤灰。通过上述技术方案，解决了现有技术中的粉煤灰制备的混凝土抗压强度低的问题。
