Waste concrete geopolymer and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to a waste concrete geopolymer. The waste concrete geopolymer comprises waste concrete, blast furnace slag,power plant fly ash and an alkali activator. The waste concrete geopolymer has very high compressive strength and breaking strength, and the strength of the waste concrete geopolymer reaches 21 MPa after the waste concrete geopolymer is cured for 3 days; and after 28 days of curing, the strength of the waste concrete geopolymer reaches 58 MPa, the breaking strength reaches 4.8 MPa, and the wasteconcrete geopolymer can be directly used as a building material.
本发明属于建筑材料技术领域，尤其涉及一种废弃混凝土地聚物，包括废弃混凝土，高炉矿渣，电厂飞灰和碱激发剂。本发明废弃混凝土地聚物具有很高的抗压强度和抗折强度，养护3天后，所述废弃混凝土地聚物的强度达到21MPa；养护28天后，所述废弃混凝土地聚物的强度达到58MPa，抗折强度达到4.8MPa，可直接作为建筑材料应用。
