High-efficiency concrete admixture

Abstract

The high-effective concrete addition agent comprises (wt%) triethanolamine 10-15, tartaric acid 2-5, iron trichloride 0.5-2, sodium chloiride 4-7, cane sugar 3-5, phosphorus-less washing powder 3-6 and water 10-20. Said additive agent can make cement concrete possess water-reducing, slow-settling, early-strength, antiflex cracking, impervious, freezing prevention, pumping and wear-resisting properties.

Description

1. Technical field [0001] The invention relates to an admixture for cement concrete, especially a high-efficiency concrete admixture. 2. Background technology [0002] In order to improve the performance of cement concrete, admixtures or admixtures are often added to the cement concrete. The admixtures or admixtures currently sold in the market are single-function and can only solve a certain performance problem of cement concrete. For example, NNO water reducing agent can only reduce water; early strength agent can only achieve early strength. Effect; the retarder can only play a retarding effect, but for cement concrete, there are many properties that need to be solved. This single effect cannot fully solve the performance problem of cement concrete. At the same time, it is a powdery product, which is not easy to mix well; in the maintenance of cement concrete, it needs to be covered with thermal insulation materials, which brings inconvenience to maintenance.

AI Technical Summary

Problems solved by technology

The admixtures or admixtures currently sold in the market have a single function and can only solve a certain performance problem of cement concrete. For example, NNO water reducing agent can only reduce water; early strength agent can only achieve early strength. effect; the retarder can only play a retarding effect, but for cement concrete, there are many properties that need to be solved. This single effect cannot fully solve the performance problem of cement concrete

At the same time, it is a powdery product, which is not easy to mix well; in cement concrete maintenance, it needs to be covered with thermal insulation materials, which brings inconvenience to maintenance

Disadvantages such as large blending amount and high cost

The patent of patent application No. 85108262 discloses "a concrete admixture", which can only improve the fluidity of the cement concrete composition and prevent the consistency change caused by the continuation of time before the composition is hardened. The amount of admixture is large and the cost is high. , complex construction technology and other deficiencies; the patent application No. 99116049.5 discloses "a β-teasulfonic acid formaldehyde condensate quaternary ammonium salt concrete admixture", which can only solve the dispersion ability and water-reducing and early-strength functions of concrete , but can not solve the concrete retardation, chemical corrosion resistance, antifreeze and other properties
