Abstract

The invention discloses a coagulant for ordinary silicate concrete. The mass percent of each component is: 10%-25% of calcium salt, 0.4%-5% of alcohol amines, and 1%-5% of anionic polymer. 4%, the balance is water, and the total amount is 100%. The coagulant prepared according to the present invention has good synergy with the polycarboxylate superplasticizer, can effectively shorten the concrete setting time but does not cause rapid setting, and can be widely used in various ordinary silicate concretes that have coagulation-accelerating requirements, and is especially suitable for It is suitable for the non-steam curing process of components in prefabricated component factories and concrete construction under low temperature environment.

Description

technical field [0001] The invention belongs to the technical field of cement concrete admixtures, and relates to a coagulant for ordinary Portland concrete. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous increase in infrastructure construction, more and more projects require completion within a limited period of time, which requires the addition of concrete coagulants to speed up cement hydration and shorten dehydration. Formwork and maintenance time, speed up the construction progress, shorten the construction period, and save concrete construction costs. In addition, in the production process of prefabricated components, the use of coagulants can also shorten the steam curing time of concrete or even avoid steam curing, reduce costs, increase mold turnover rate, thereby improving production efficiency and economic efficiency. [0003] Calcium chloride is the earliest concrete coagulant, which has the ad...
