All-solid-waste alkali-activated concrete and preparation method thereof
The invention provides an all-solid-waste alkali-activated concrete and a preparation method thereof. The concrete comprises powder A, an alkaline activator A, powder B and an alkaline activator B, wherein the powder A is selected from industrial solid waste rich in silicon, aluminum and calcium, the content of calcium in the powder A is larger than or equal to 10% and smaller than 50%, the content of silicon and aluminum in the powder A is larger than or equal to 50% and smaller than 100%, the molar ratio of silicon to aluminum is 2.0-3.5, the content of a glass body exceeds 50%; the powder Bis selected from industrial solid waste rich in silicon, aluminum and calcium, the content of calcium in the powder B is greater than 0 and less than 10%, the content of silicon and aluminum is greater than or equal to 75% and less than 100%, the molar ratio of silicon to aluminum is 1.5-4.0, the content of a glass body exceeds 50%; and the alkaline activator A and the alkaline activator B respectively comprise alkali metal silicate, alkaline hydroxide and water in different mass ratios. The strength of the all-solid-waste type alkali-activated concrete ranges from 43.28 MPa to 58.74 MPa.
