Abstract
The invention discloses a concrete additive which is prepared from, by mass parts, 10-20 parts of wollastonite powder, 5-8 parts of rosin, 10-15 parts of bentonite, 10-15 parts of calcium carbonate, 1-5 parts of sodium triphosphate, 5-8 parts of calcium chloride, 0.1-2 parts of potassium permanganate, 10-15 parts of melamine, 15-20 parts of cellulose water-retaining material, 1-2 parts of sodium nitrite, 3-6 parts of active magnesium oxide, 20-30 parts of coal residue and 5-10 parts of water. The concrete additive enables the water-reducing rate of concrete to reach 25% or above.
Description
Technical field
The present invention relates to a kind of concrete additive.
Background technology
Concrete admixture refers to before mixing concrete 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 large that water reducer used in the market also exists volume, and water reducing ability is poor, the shortcoming of plasticization effect difference, cannot meet the requirement in market.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of concrete additive, and concrete water-reducing rate can be made to reach more than 25%.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
Thering is provided a kind of concrete additive, is be prepared from by the composition of following mass fraction: wollastonite powder 10 ~ 20 parts, rosin 5 ~ 8 parts, wilkinite 10 ~ 15 parts, 10 ~ 15 parts, calcium carbonate, tripoly phosphate sodium STPP 1 ~ 5 part, 5 ~ 8 parts, calcium chloride, 0.1 ~ 2 part, potassium permanganate, trimeric cyanamide 10 ~ 15 parts, Mierocrystalline cellulose water-keeping material 15 ~ 20 parts, Sodium Nitrite 1 ~ 2 part, activated magnesia 3 ~ 6 parts, cinder 20 ~ 30 parts and 5 ~ 10 parts, water.
In a preferred embodiment of the present invention, described Mierocrystalline cellulose water-keeping material is one or more the mixture in Vltra tears, hydroxyethylmethyl-cellulose or methylcellulose gum.
In a preferred embodiment of the present invention, in powdery, particle diameter≤0.08mm.
In a preferred embodiment of the present invention, be prepared from by the composition of following mass fraction: wollastonite powder 15 parts, rosin 5 parts, wilkinite 12 parts, 15 parts, calcium carbonate, tripoly phosphate sodium STPP 3 parts, 6 parts, calcium chloride, 0.9 part, potassium permanganate, trimeric cyanamide 12 parts, Mierocrystalline cellulose water-keeping material 20 parts, Sodium Nitrite 1.5 parts, activated magnesia 5 parts, cinder 30 parts and 8 parts, water.
The invention has the beneficial effects as follows: a kind of concrete additive of the present invention, water-reducing rate can reach 25%, and plasticization effect is good, can obviously increase the concrete slump, improve concrete cohesiveness and workability.
