Cement concrete curing agent and preparation method thereof

Abstract

The invention relates to a building material cement concrete curing agent which comprises the following components by weight percent: 10 to 20 percent of sodium silicate, 2 to 6 percent of urea, 1 to 3 percent of triethanolamine, 0.2 to 5 percent of sodium fluosilicate, and the rest of water. The total weight of the components is 100 percent. The curing agent can prevent the surface of the concrete from being dried too early, reduce concrete shrinkage and cracking, achieve the ideal effect of improving the appearance and the internal quality of the concrete, and can save the building cost.

Description

technical field [0001] The invention relates to a cement concrete curing agent for building materials. Background technique [0002] At present, the natural curing method is generally used in domestic concrete curing. After years of practice and research on cement concrete curing methods, it is found that the construction unit neglects the concrete curing, and the curing cannot be carried out in a timely manner according to the specification requirements and deadlines, and the curing quality is difficult to control and manage. It does not meet the standards required by natural conservation, which not only affects the growth of the early strength of concrete, but more importantly, due to the rapid evaporation and loss of moisture on the concrete surface, the surface of the concrete shrinks, cracks, and fluffs, which seriously affects the overall quality of the concrete and other properties. Play. The follow-up investigation after the operation of the built cement concrete bui...

Problems solved by technology

The natural maintenance of watering wastes water resources, and it is difficult to guarantee the quality of maintenance; the maintenance construction of covering grass curtains or plastic films is difficult, which affects the next process; the chemical maintenance of spraying curing agent has the advantages of simple construction and easy quality assurance, so with the construction The development of the industry is respected by people

Wherein chemical curing agent is generally divided into three kinds again, i.e. water glass type curing agent, emulsion type curing agent, resin type curing agent, wherein its quality of existing water glass type curing agent generally does not reach "cement concrete curing agent" ( JC901-2002) standard requirements; when the emulsion type curing agent is applied, a film is easy to form on the concrete surface, which is unfavorable to the subsequent plastering project; the cost of the resin type curing agent is too high, and it is unacceptable for general projects
