Abstract
The invention discloses a chloride concrete admixture. The chloride concrete admixture is prepared from the following materials in parts by weight: 10-15 parts of ferric chloride, 25-30 parts of calcium chloride, 3-8 parts of sodium alkyl benzene sulfonate, 0.3-0.5 parts of hexamethoxymethylmelamine, 25-30 parts of sodium methylene dinaphthalenesulfonate and 120-180 parts of water. The chloride concrete admixture has the advantages of rich and easily available raw materials, low cost, simple process flow, excellent product properties and convenience in construction, also has the effects of long-setting, reinforcing and waterproof effects, and especially is capable of remarkably reducing heat of hydration, decreasing the slump loss and improving the thixotropy of the concrete.
Description
Technical field
The present invention relates to a kind of concrete admixture, relate in particular to a kind of muriate concrete admixture and preparation method thereof.
Background technology
Concrete admixture is to mix in ready-mixed concrete process, accounts for cement quality below 5%, can significantly improve the chemical substance of concrete performance, mixes admixture in concrete, has less investment, instant effect, a technical economic benefit outstanding feature.Along with the continuous progress of science and technology, admixture is applied more and more, and admixture has become the 5th kind important component of concrete except 4 kinds of basal components.
Existing, concrete admixture is divided into four classes by its major function: 1 improves the admixture of concrete mix rheological property.Comprise various water reducers, air entrapment agent and pumping agent etc.; 2 regulate the admixture of concrete coagulating time, Hardenability.Comprise retardant, hardening accelerator and accelerating chemicals etc.; 3 improve the admixture of concrete durability.Comprise air entrapment agent, water-resisting agent and rust inhibitor etc.; 4 improve the admixture of other performance of concrete.Comprise air entraining agent, swelling agent, tinting material, water-resisting agent and pumping agent etc.
