Abstract
Is the invention discloses a kind of high efficiency water reducing agent, it mixed by the raw material of following weight part: beta-naphthalenesulfonic-acid salt formaldehyde condensation products? 50-60, polyethylene glycol monomethyl ethermethacrylic acid esters 20-30, calcium lignin sulphonate 15-25, PEP-101 10-15, trehalose 2-4, silicone powder 1.5-2.5, shale ashes 4-8, sodium bisulfite 2.5-4.5, polyoxyethylene 5-10, aluminium triphosphate 8-14, cocounut oil acyl diethanolamine 2-3, dinonyl naphthalene sulfonate barium? 1-2, urotropine 2-3, auxiliary agent 3-5.Water reducer water-reducing rate of the present invention is high, good fluidity, can obviously improve concrete flowability and workability, and early strong Be very effective after final set, can increase substantially the intensity in concrete each length of time, be applicable to all kinds of concrete.
Description
Technical field
The present invention relates to a kind of high efficiency water reducing agent, belong to concrete admixture field.
Background technology
Concrete admixture, is called for short admixture, refers to before mixing concrete mixing or mixes to improve the material of concrete performance in mix process.Because admixture can improve concrete performance effectively, and have good economic benefit, be all widely used in many countries, the application in engineering more and more comes into one's own, and becomes material indispensable in concrete.Wherein water reducer is most important a kind of admixture in concrete, and it under concrete workability and cement consumption permanence condition, can reduce mixing water amount, improve concrete strength; Or under workability and intensity permanence condition, save cement consumption.But it is low that water reducer used in the market also exists water-reducing rate, poor fluidity, the shortcoming that intensity is low, cannot meet the requirement in market.
Summary of the invention
The object of the invention is to solve the defect existed in prior art, a kind of high water reducing rate, high workability, the early significant high efficiency water reducing agent of potent fruit are provided.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of high efficiency water reducing agent, is mixed by the raw material of following weight part: beta-naphthalenesulfonic-acid salt formaldehyde condensation products 50-60, polyethylene glycol monomethyl ethermethacrylic acid esters 20-30, calcium lignin sulphonate 15-25, PEP-101 10-15, trehalose 2-4, silicone powder 1.5-2.5, shale ashes 4-8, sodium bisulfite 2.5-4.5, polyoxyethylene 5-10, aluminium triphosphate 8-14, cocounut oil acyl diethanolamine 2-3, dinonyl naphthalene sulfonate barium 1-2, urotropine 2-3, auxiliary agent 3-5;
Described auxiliary agent is made up of the raw material of following weight part: magnesia 10-15, Humic acid Magnesium 3-6, ammonium benzoate 2-4, α-sodium olefin sulfonate 6-12, myo-Inositol hexaphosphate 1.5-2.5, iso-butylene triethoxyl silane 3-5, poly-ferric chloride 5-10, germanite powder 12-18, titanium dioxide 5-10, myristyl glucoside 1-2, polyamide wax 4-6, lithium magnesium silicate 2-3, tea saponin 1.5-2.5;
Above-mentioned magnesia, germanite powder, titanium dioxide are mixed, then α-sodium olefin sulfonate, iso-butylene triethoxyl silane, polyamide wax, lithium magnesium silicate is added, 10-15min is stirred under 40-60 DEG C of bath temperature, remaining raw material is added after being cooled to normal temperature, stir, dry, obtain described auxiliary agent.
Beneficial effect of the present invention:
Water reducer water-reducing rate of the present invention is high, good fluidity, can obviously improve concrete flowability and workability, the concrete initial slump of identical water cement ratio can be made to improve more than 15m, water-reducing rate can reach 20-30%, early strong Be very effective after final set, the intensity in concrete each length of time can be increased substantially, be applicable to all kinds of concrete.
