Abstract
The invention discloses a concrete early-strength agent. The concrete early-strength agent is prepared from the following components in parts by weight: 28-33 parts of calcium formate, 15-24 parts of sodium chloride, 12-16 parts of potassium chloride, 6-9 parts of potassium aluminium sulfate, 5-7 parts of tri-isopropanolamine and 2-4 parts of ethanol. The concrete early-strength agent has the beneficial effects that 1. the concrete early-strength agent has no corrosion effect on steel bars and is suitable for all civil, industrial building and prestressed reinforced concrete components, mortar and the like; 2. the concrete early-strength agent can adapt to construction at a low temperature in early winter and early spring; 3. the concrete early-strength agent is used in silicate cement and has particularly remarkable effect on enhancement and modification of slag cement.
Description
Technical field
The present invention relates to a kind of concrete early strength agent.
Background technology
Concrete early strength agent refers to and can improve early age strength of concrete, and the admixture that later strength is not made significant difference.Its Main Function is to accelerate hydrated cementitious speed, promotes the development of early strength on coagulation.Traditional hardening accelerator, larger to Architectural Corrosion, and under low temperature condition effect extreme difference.
Summary of the invention
Object of the present invention is exactly for above-mentioned defect of the prior art, provides a kind of corrodibility little, and can adapt to the concrete early strength agent of multiple operating environments.
To achieve these goals, technical scheme provided by the invention is: a kind of concrete early strength agent, is comprised of the following component according to weight part meter: calcium formiate 28-33 part, sodium-chlor 15-24 part, Repone K 12-16 part, potassium aluminium sulfate 6-9 part, tri-isopropanolamine 5-7 part, ethanol 2-4 part.
Further, above-mentioned a kind of concrete early strength agent, is comprised of the following component according to weight part meter: 30 parts of calcium formiates, 20 parts, sodium-chlor, 14 parts, Repone K, 8 parts of potassium aluminium sulfates, 6 parts of tri-isopropanolamines, 3 parts of ethanol.
Beneficial effect of the present invention is:
1,, to the effect of reinforcing bar non-corroding, be applicable to that all are civilian, Industrial buildings and prestressed reinforced concrete member, mortar etc.;
2, hardening accelerator can adapt to early winter and construct early spring under cold condition;
3, for portland-type cement, particularly remarkable to the enhancing of slag cement and modifying function.
