Abstract
The present invention relates to concrete admixture, including the raw material of following weight portion: 50 60 parts of polycarboxylic acid mother solution, protect and collapse agent 12 40 parts, sodium gluconate 5 25 parts, hydroxypropyl cellulose 25 110 parts.Also including that defoamer and air entraining agent, described defoamer account for the 0.1 0.4 ‰ of additive total amount, described defoamer accounts for the 0.1 0.3 ‰ of additive total amount.Described polycarboxylic acid mother solution is the mother solution without ball base propanoic acid.The present invention improves the durability of concrete, improves the intensity of concrete, and environmental protection.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of concrete admixture.
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.Additive can improve the performance of concrete effectively, and has
Good economic benefit.It is widely used in many countries, becomes material indispensable in concrete.Due at present
Containing some harmful compositions in major part concrete, make at the fraud that people causes a disease more and more, so country is in green
Under the overall background of environmental protection, green, environmental protection, healthy concrete concrete are particularly important.
Summary of the invention
It is an object of the invention to provide a kind of concrete admixture.The present invention improves the durability of concrete, improves
The intensity of concrete, and environmental protection.
The technical solution used in the present invention: concrete admixture, it is characterised in that include the raw material of following weight portion: poly-carboxylic
Acids mother solution 50-60 part, protect and collapse agent 12-40 part, sodium gluconate 5-25 part, hydroxypropyl cellulose 25-110 part.
Further, also include that defoamer, air entraining agent, described defoamer account for the 0.1-0.4 ‰ of additive total amount, described in disappear
Infusion accounts for the 0.1-0.3 ‰ of additive total amount.
Further, described polycarboxylic acid mother solution is the mother solution without ball base propanoic acid.
Compared with prior art it provides the benefit that the present invention: the invention provides a kind of coagulation being made up of various ingredients
Soil additive, the preparation of this additive is simple, and the slump that can be reduced concrete by the science collocation of each component is lost, improved
The workability of concrete, it is ensured that the mobility of concrete, additionally, the existence of composition can also improve the adsorption-like of earth in additive
State, reduction clay content is on concrete, the impact of water reducer, and in the case of clay content is up to 10%, the concrete performance of gained is still
So disclosure satisfy that requirement；Additionally, due to polycarboxylic acid mother solution of the present invention without ball base propanoic acid so that the living environment of people is more healthy
Environmental protection, it is to avoid the generation of some disease.
Detailed description of the invention
Below by specific embodiment, the present invention is further detailed.
