Abstract
The invention provides a kind of concrete admixture, it is prepared by the raw materials in: 10 20 parts of ferrous sulfate, 24 parts of kieselguhr, barium nitrate 24 parts, vinylite 25 parts, 2 methoxyphenyl-boronic acid 35 parts etc., the additive of the application can make water-reducing rate reach more than 45%, the highest can reach 56%；Meanwhile, this additive is fine for the holding of slump, and in 2 hours, the variable quantity of its slump is less than 4mm, it addition, bleeding rate ratio can reach less than 40%, compressive strength rate is also improved.
Description
Technical field
The present invention relates to a kind of concrete admixture and preparation method thereof, belong to chemical technology field.
Background technology
Concrete admixture is to mix during mixing concrete, in order to improve the material of concrete performance, according to
The regulation of Its Relevant Technology Standards, its incorporation is not more than the 5% of cement quality.The Main Function of concrete admixture is to improve newly
The performance of mixed concrete and the performance of raising maturing.In concrete admixture, mainly include mixing for improving concrete
The water reducer of compound rheological property, air entraining agent, for regulating concrete coagulating time, the retarder of hardening capacity, early strength agent, use
In the waterproofing agent etc. improving concrete durability.
Summary of the invention
Goal of the invention: it is an object of the invention to provide a kind of obvious concrete admixture of effect and preparation method thereof.
Technical scheme: it is an object of the invention to by following scheme realization:
A kind of concrete admixture, is prepared by the raw materials in: ferrous sulfate 10-20 part, ferric chloride 6-10
Part, silicon powder 0.4-0.8 part, oxidized asphalt 0.4-0.8 part, Pulvis Talci 1.4-1.8 part, 4-(trifluoromethoxy) methyl phenyl ethers anisole 1-2
Part, kieselguhr 2-4 part, barium nitrate 2-4 part, vinylite 2-5 part, 2-methoxyphenyl-boronic acid 3-5 part, phenylmalonate 4-6
Part, 4-vinylphenylboronic acid 1-3 part, thiophenyl ethyl acetate 2-4 part, calcium carbonate 3-5 part, ammonium glycyrrhizinate 4-8 part, titanium dioxide
Silicon 2-4 part, ethyl cellosolve acetate 4-8 part, water 20-40 part.
The preparation method of described concrete admixture, comprises the following steps: weigh various raw material by formula proportion, and stirring is mixed
Close and get final product.
Beneficial effect:
The present invention is modified by proportioning raw materials, and the additive of the application can make water-reducing rate reach more than 45%,
Height can reach 56%；Meanwhile, this additive is fine for the holding of slump, and in 2 hours, the variable quantity of its slump is little
In 4mm, it addition, bleeding rate ratio can reach less than 40%, compressive strength rate is also improved, cost of manufacture is low, is conducive to
Promote the use of.
Detailed description of the invention
Form by the following examples, is described in further detail the foregoing of the present invention again, but should be by this
Being interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to Examples below, all technology realized based on foregoing of the present invention are equal
Belong to the scope of the present invention.
Embodiment 1: take 10 parts of ferrous sulfate, 4 parts of kieselguhr, ferric chloride 6 parts, silicon powder 0.8 part, oxidized asphalt 0.4

Part, silicon dioxide 2 parts, ethyl cellosolve acetate 8 parts, 40 parts of water, preparation method, comprise the following steps: claim by formula proportion
Taking various raw material, stirring mixes and get final product.
Above-mentioned raw materials is all purchased from Nanjing chemical reagent limited company.
Embodiment 2: effect assessment of the present invention (prepares sample by above-described embodiment 1 method)
Being prepared as lightweight concrete additive by above-described embodiment 1, obtained additive, by cement quality 0.6%
Ratio adds, and cement uses concrete inspection reference cement, grain fineness number modulus 2.6, and stone uses the rubble of graduation two, then joins
Relevant criterion according to GB8076-2008 is tested, and result is as follows:
Water-reducing rate reaches 42.5%, and in 2 hours, the variable quantity of its slump is 3.98mm, and bleeding rate ratio is 48%, 1d
Compressive strength rate is 182%, and 3d compressive strength rate is 175%, and 7d compressive strength rate is 149%, and 28d compressive strength rate is
148%.
