Abstract

The present invention discloses a composite liquid for concrete, which is composed of a naphthalene water reducing agent, lignosulfonic acid, inorganic calcium salt, citric acid and water. The present invention has the various functions of retardation, waterproof performance, water reduction, etc.; furthermore, the present invention has the advantages of good performance, no corrosion to steel bars, obvious early strength and enhancement effects, simple technology and low cost, the mixed amount of the present invention is cement is 2%, and the present invention can be suitable for mass concrete pouring and waterproof concrete engineering and pumped concrete.

Description

A kind of composite concrete liquid
The present invention relates to a kind of concrete admixture, is multi-functional composite concrete liquids such as a kind of collection slow setting, waterproof, diminishing.
CN1082008A discloses a kind of composite concrete liquid, is calcite is dropped into concentrated hydrochloric acid reaction 4～6 hours, adds electrolytic aluminum, iron trichloride etc. and makes, this complex liquid chlorinity height, steel bar corrosion is had promoter action, and wherein contained iron(ic) chloride can increase concrete shrinkage, causes the crack; Cost is higher; Volume big (3%) in cement, and early potent fruit relatively a little less than.
The object of the present invention is to provide does not a kind ofly have corrosion to reinforcing bar, and concrete shrinkage is not had influence, and cost is low, and volume is little, and early potent fruit is obvious, and collection slow setting, waterproof, diminishing, curing, expansion is multi-functional and the composite concrete liquid of more excellent performance.
Complex liquid of the present invention is made up of following component and weight part:
Naphthalene water reducer 15-22
Calcium lignin sulphonate 10-15
Citric acid 5-10
Inorganic calcium salt 0.008-0.03
Surplus is a water.
Its preparation method is that calcium lignin sulphonate, inorganic calcium salt, citric acid powder are broken to 200 sieve meshes, adds excess water, is heated to 45-50 ℃, stirs 30-40 minute to dissolving, and cooling adds naphthalene water reducer again, stirs, and is finished product, product P H=7～8.
Complex liquid of the present invention is not chloride, so reinforcing bar is not had corrosion, does not contain FeCl 3Concrete shrinkage is not had influence, tangible morning of strong and reinforced effects is arranged, increased by 60%, 28 day and improve more than 15% volume little (2%) in cement in 3 days.Multiple functions such as collection slow setting, waterproof, diminishing, curing, expansion; Technology is simple, and cost is low, excellent property, and its presetting period is 6-7h, and final set is 10-12h, and water-reducing rate reaches 18-25%, and ultimate compression strength is big, applicable to mass concrete cast and water-proof concrete engineering and pump concrete application.
