Abstract
The invention relates to quick-setting cement mortar. The quick-setting cement mortar is a liquid mixture prepared from sulphate aluminium cement, butadiene styrene rubber latex, a water reducing agent, fibers, sodium sulfate, river sand and water in a certain weight ratio by a certain method. Compared with similar cement mortar, the drying time of the obtained quick-setting cement mortar is faster, the compression strength and the rupture strength are higher, the adaptability is higher and the cost is lower.
Description
Technical field
The present invention relates to building material field, is specifically related to a kind of construction work quick-setting cement mortar and preparation method thereof.
Background technology
In building material field, quick-drying time requirement to sand-cement slurry is fewer and feweri, simultaneously, must guarantee that the cement after rapid drying has the better characteristics such as anti-intensity, therefore, the hot issue that to seek a kind of like this quick-setting cement mortar be building material field always.Disclosing a kind of polyacrylate modified cement take polyvinyl alcohol as stablizer at US5753036, is that 5000～45000 polyvinyl alcohol, polyacrylic ester, cement and filler consist of by molecular-weight average.CN1730908 discloses a kind of method for reinforcing and protecting to inner surface of tunnel, by adding polyacrylate emulsion and polypropylene fibre to improve the surface strength of inner surface of tunnel, solved crack, infiltration and the high temperature explosion problem of inner surface of tunnel in cement waterproofing mortar.CN1483692 discloses a kind of cement concrete mixture that adds polyacrylonitrile fibre.CN1415572 discloses a kind of Polymer-Modified Mortar patching material, is made of Portland cement or short-term strength cement, styrene-butadiene rubber(SBR), sodium carbonate, trolamine.At present the polymkeric substance of sand-cement slurry modification is mainly polyacrylate dispersion, EVA emulsion or styrene-butadiene emulsion.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 the reason such as polymkeric substance breakdown of emulsion, cause extend and strength decreased the time of coagulation of sand-cement slurry, thereby affected the net effect of sand-cement slurry.CN102167559 discloses and has a kind ofly combined to the sand-cement slurry modification with SBR emulsion and polyaminoester emulsion.But in the process of reality, polymkeric substance and cement consistency are still undesirable, cause extend and strength decreased the time of coagulation of sand-cement slurry, thereby have affected the net effect of sand-cement slurry.
On the basis of these prior aries, the present invention is to polymer-modified, water reducer, fibrous packing component further experiment, find when adopting SBR emulsion properties-correcting agent, a kind of water reducer of new proportioning and adopt a certain proportion of conjugated fibre, its experiment effect has significant progress than above-mentioned effect of the prior art, and has reduced cost.
