Method for preparing concrete floor tile with high strength

Abstract

The invention discloses a method for preparing a concrete floor tile with high strength. The method comprises the following steps that light calcium carbonate, building rubbish, fly ash, vermiculite power and polyamide resin are evenly mixed to obtain a premix a; cement, quick lime, blast furnace slag, hollow glass beads, kieselguhr, gravel, microcrystalline cellulose, wollastonite powder and aluminum borate whisker are evenly mixed to obtain a premix b; the premix a, the premix b and water are evenly mixed, vibration and extrusion molding, demoulding and maintenance are carried out to obtainthe concrete floor tile with the high strength. The provided method for preparing the concrete floor tile with the high strength has the advantages that the obtained concrete floor tile has small volume weight, excellent compressive strength and rupture strength, and good thermal insulation performance.

Description

technical field

[0001] The invention relates to the technical field of concrete bricks, in particular to a preparation method of high-strength concrete bricks. Background technique

[0002] At present, my country's construction waste disposal methods mainly include stacking and burying, which is no longer in line with my country's strategic policy of building a resource-saving and environment-friendly society. The best way at present is to reuse construction waste as a resource.

[0003] After the construction waste is crushed, cleaned and graded, it is mixed with a certain proportion and graded to make concrete bricks, which can realize the reuse of construction waste and significantly save costs, but the strength of the concrete bricks prepared with it is low. The volume is huge and needs to be solved urgently. Contents of the invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing h...
