Abstract

The invention relates to the field of improving the curing time of the concrete in the water, in particular to a curing agent for the underwater cast concrete. The invention solves the problems of the existing underwater concrete cast that the construction technique is complicate, the manufacturing cost is high and the concrete intensity is poor and so on; counted by 100 parts of cement mass in the concrete, the curing agent consists of 0.8-2 parts of 1% of polyvinyl alcohol solution, 1-5 parts of 2% of ferric chloride solution, 1.5-2 parts of sodium metalluminate and 12 parts of concrete complexing agent; the concrete complexing agent is composed of silica, fluorite, hexadecyl sodium benzenesulfonate, hydroxycarboxylic acid and fatty group hydroxy sulphonate high efficiency water reducing agent; the underwater cast concrete has dispersibility resistance, viscidity, high plasticity and bleeding property, which leads the concrete mixture not to isolate and keep together during the falling process and can keep the uniformity of the mixture; the addition of the concrete complexing agent can improve the compression resistance rating, the sodium metalluminate and so on can ensure that the concrete is cured in the water; the invention is simple in technique, low in construction cost and reliable in engineering quality.

Description

technical field [0001] The invention relates to the field of increasing the solidification time of concrete in water, in particular to a coagulant for pouring concrete in water. Background technique [0002] With the development of industry and the expansion of development scale, there are more and more underwater projects such as bridge pile foundation engineering, flood control and emergency engineering, anticorrosion of underwater structures, bank revetment, etc. The effect of scouring, the cement paste in the concrete mixture is lost, not only the cement paste in the cast body is reduced, but also the water / glue ratio is greatly increased, the uniformity of the concrete structure is extremely poor, and the lightness and durability are severely reduced. In order to solve the above problems, the water isolation method is usually used, that is, to reduce the concrete mixture, or even avoid contact with water, so as to solve the pouring and quality problems of concrete in th...
