Abstract
The invention relates to quick-setting cement mortar and a preparation method thereof. The quick-setting cement mortar is concretely prepared from materials such as sulphate aluminium cement, styrene butadiene rubber emulsion, polyurethane emulsion, a water reducer, trolamine, droxyethylcellulose, fibre, river sand, water and the like according to a certain weight ratio. The quick-setting cement mortar has the characteristics of quickness in setting at normal temperature, high strength in the early stage, crack resistance, good durability and the like, can be widely applied to the fields such as embankment reinforcement, channel impermeability, soil and water conservation, side slope protection, quick repair of concrete road surfaces, and the like.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of construction work with rapid hardening cement mortar and preparation method thereof.
Background technology
The aluminosulfate cement mortar has outstanding does powerful feature early soon, and has performances such as volume microdilatancy, anticorrosive and low basicity, is normally used for making anticorrosion impervious material, fast repairing material etc.But, the anticorrosion impervious and patching material of only making with the aluminosulfate cement mortar, its later strength porosity lower, that be prone to shrinkage cracking, hydration and hardening slurry causes the resistance to corrosion can not engineering demands more greatly.In sand-cement slurry, add a small amount of organic high molecular polymer and fiber; Can effectively reduce the hole in the sand-cement slurry; Make sand-cement slurry obtain highly dense solidity; Be unlikely to make the fragility of sand-cement slurry to strengthen again, obtain dried, high-strength, impervious, corrosion resistant soon cement mortar material, thus the use field of having widened sand-cement slurry.
It is the polyacrylate modified cement of stablizer with the Z 150PH that US5753036 discloses a kind of, is that 5000～45000 Z 150PH, polyacrylic ester, cement and filler constitute by molecular-weight average.CN1730908 discloses a kind of method for reinforcing and protecting to inner surface of tunnel; Improve the surface strength of inner surface of tunnel through in cement waterproofing mortar, adding ROHM emulsion and polypropylene fibre, solved crack, infiltration and the high temperature explosion problem of inner surface of tunnel.CN1483692 discloses a kind of cement concrete mixture that adds polyacrylonitrile fibre.CN1415572 discloses a kind of polymer modification mortar patching material, is made up of Portland cement or short-term strength cement, styrene-butadiene rubber(SBR), yellow soda ash, trolamine.Polymkeric substance to the sand-cement slurry modification is mainly polyacrylate emulsion, EVA emulsion or styrene-butadiene emulsion at present.Polymer emulsion can effectively improve the impervious and anti-shrinkage cracking performance of sand-cement slurry; But in the process of preparation polymer cement mortar; Because of polymkeric substance and the cement consistency is relatively poor and reason such as polymkeric substance breakdown of emulsion; Cause prolong and the intensity reduction time of coagulation of sand-cement slurry, thereby influenced the net effect of sand-cement slurry.
Summary of the invention
The objective of the invention is to solve the problem of the rate of set that exists in the present use polymer modification rapid hardening cement mortar, a kind of rapid hardening cement mortar and preparation method thereof is provided.
The rapid hardening cement mortar that the present invention proposes is the liquid form mixt that is formed according to a certain weight ratio by materials such as aluminosulfate cement, SBR emulsion, polyaminoester emulsion, water reducer, trolamine, Natvosol, fiber, river sand, water.Comprising of raw material:
