Abstract
The invention relates to a concrete interface agent which uses modified S95 grade slag powder as a raw material, and belongs to the technical field of solid waste comprehensive utilization and chemical building material. The raw material proportion in the agent of the invention is as follows: 35-50% of modified S95 grade slag powder, 15-30% of cement, 30-45% of sand, 2.0-5.0% of emulsion powder, 0.1-0.5% of water-retaining agent and 0.1-0.3% of anti-cracking agent. According to proportion, materials are weighed and orderly placed into a blender and mixed adequately to obtain the interface treating agent. The interface agent is packaged in form of powder and is convenient to convey. The interface treating agent can be used on the spot by adding water and agitating uniformly. The environmentally-friendly concrete interface treating agent has excellent water-retaining performance, strong construction performance and bonding force and the like.
Description
Technical field
The present invention relates to a kind of is the feedstock production concrete interface treating agent with the modified S 95-grade slag powder, belongs to solid waste comprehensive utilization and chemical building material technical field.
Background technology
Concrete interface treating agent has superpower bonding force, good water tolerance, stability to aging.Improve motar and can effectively avoid the coat of plaster hollowing, come off problems such as shrinkage cracking the cohesive strength of basic unit.Be used to handle surfaces such as concrete, gas concrete, Dinas brickes and flyash brick, solve, cause the coat of plaster hollowing, ftracture, peel off etc. because these water absorbent surface property are strong or smooth to cause that the interface is difficult for bonding.Can strengthen between the new-old concrete greatly and the cohesive force of concrete and motar.The cutter hair operation that can replace the conventional concrete surface; Improve gas concrete surface plastering technology; Also has very strong perviousness; Can fully soak into nearly layer material surface, improve the adsorptive power of newly smearing putty and base material and increase viscosifying power, be the indispensable supplementary material of modern architecture and decoration construction.
In order to solve problems such as ubiquitous hollowing ftractures between body of wall basic unit and the float coat, flake, come off, and reduce the dependence of interfacial agents, press for and seek a kind of environmentally friendly material cement.
Summary of the invention
The purpose of this invention is to provide a kind of modified S 95-grade slag powder that utilizes and be the feedstock production concrete interface treating agent.
