Abstract

The invention discloses a chloroprene rubber-alkaline residue-cement composite cementing material, and a preparation method and device thereof, and belongs to the technical field of cementing materials. The composite cementing material comprises following raw materials in parts by weight: 30 to 40 parts of cement, 20 to 35 parts of alkaline residue particles, 20 to 30 parts of fly ash, 10 to 20 parts of waste chloroprene rubber powder, 1 to 10 parts of fibers, and 0 to 2 parts of a water reducer. The preparation method comprises following steps: preprocessing chloroprene rubber; preprocessingalkaline residues; preparing raw materials; preparing a basic material; and preparing the composite cementing material. The problems that in the prior art, a concrete cementing material is highly crispy and the tensile strength and compressive strength are low are solved.

Description

technical field [0001] The invention relates to the technical field of cementitious materials, more specifically, it relates to a neoprene-alkali slag-cement composite cementitious material, a preparation method and a device. Background technique [0002] Among civil engineering materials, any material that can bond granular or massive materials into a whole through a series of physical and chemical changes is collectively referred to as cementitious materials. [0003] The cementitious material used in traditional building concrete is generally composed of cement, mineral powder, and fly ash mixed in a certain proportion. Although the internal structure of the concrete designed in this way is relatively compact, it is brittle and has low tensile and compressive strength. Once a crack appears, the crack will expand along the perimeter of the crack, causing the crack to elongate. Contents of the invention [0004] In view of the deficiencies in the prior art, the object of...
