Processing technology of concrete doped with waste concrete blocks and recycled concrete prepared by processing technology
The invention discloses a processing technology of concrete doped with waste concrete blocks and recycled concrete prepared through the processing technology, and relates to the technical field of building materials. A processing technology of concrete doped with waste concrete blocks comprises the following steps: S1, pretreatment: specifically, taking and smashing the waste concrete blocks intoold concrete particles, taking alginate fibers, adding aminopropyltriethoxysilane and the nano Beta molecular sieve, uniformly mixing, adding water, stirring, adding the old concrete particles, uniformly stirring, and drying to obtain recycled aggregate, S2, premixing: taking premixed raw materials, adding recycled aggregate, and uniformly mixing to obtain powder, wherein the premixed raw materials comprise coarse aggregate, fine aggregate and fly ash, and S3, concrete preparation: taking water, adding additives, stirring, adding powder, adding cement, and continuously stirring to obtain recycled concrete, wherein the additive comprises a water reducing agent. The processing technology has the advantage that the fracture resistance of the product can be improved.
