Reactive powder concrete doped with granite powder and preparation method thereof
The invention provides a reactive powder concrete doped with granite powder and a preparation method thereof, belonging to building materials. The reactive powder concrete doped with the granite powder is prepared from raw materials of cement, silicon ash, a water reducing agent, river sand, water and the granite powder. The method comprises the following steps: uniformly spreading the granite powder in a tray, then placing the tray in an oven and carrying out drying and sieving, and removing impurities in the granite powder; cleaning a test mold, removing debris inside the test mold, coating the inner surface of the test mold with a layer of machine oil and a layer of a mold release agent; pouring the cement, the silicon ash, the river sand and the granite powder into a mixer, and carrying out dry mixing; then adding the water dissolved with the water reducing agent, and carrying out stirring; pouring the obtained product in the test mold, then placing the test mold on a vibrating table, carrying out vibration until the surface of the test mold emerges slurry, then carrying out stopping, and cutting excess concrete with a spatula until the surface of the test mold is smoothed; and carrying out standing and demolding, then transferring a demolded test specimen into an autoclave and carrying out autoclave curing, and after autoclave curing is completed, carrying out transferring into a standard curing room and carrying out curing until a specified age of concrete is achieved so as to obtain the reactive powder concrete doped with the granite powder.
