Abstract
The present invention relates to building concrete field, and in particular to a kind of concrete slump retaining agent.Each material is prepared from by following percentage by weight：HPEG：30 35%, acrylic acid：0.1 0.5%, hydrogen peroxide：0.05 0.1%, mercaptopropionic acid：0.01 0.03%, ascorbic acid：0.006-0.008%, acrylic acid hydroxyl ester：2 3%, sodium hydroxide：0.1 0.2%, water：62‑67%.The present invention not only improves the durability of concrete, improves the slump holding capacity of concrete, and environmental protection.
Description
Technical field
The present invention relates to building concrete field, and in particular to a kind of concrete slump retaining agent.
Background technology
At present, slump retaining agent is can to keep the additive of concrete slump not immediate loss, delays hydrated cementitious to condense,
Reach the effect for keeping the slump.Containing some harmful compositions in most of concrete slump retaining agent, make one pathogenic
More and more at disadvantage, so country is under the overall background of environmental protection, green, environmental protection, the concrete slump retaining agent of health seem outstanding
To be important.
The content of the invention
To solve the deficiencies in the prior art, the present invention provides a kind of concrete slump retaining agent, and the present invention not only improves concrete
Durability, improve the slump holding capacity of concrete, and environmental protection.
It is to solve the technical scheme that is used of technical problem：A kind of concrete slump retaining agent, each material presses following weight
Percentage is prepared from：HPEG：30-35%, acrylic acid：0.1-0.5%, hydrogen peroxide：0.05-0.1%, mercaptopropionic acid：0.01-
0.03%, ascorbic acid：0.006-0.008%, acrylic acid hydroxyl ester：2-3%, sodium hydroxide：0.1-0.2%, water：62-67%.
The beneficial effects of the invention are as follows：Combined, arranged in pairs or groups by the science of each component, for sandstone using various ingredients
The material Concrete that second-rate or cement adaptability is bad, binder materials is less, can significantly improve collapsing for concrete
Degree of falling holding capacity, bag slurry ability, especially in the case of some general retarder are insurmountable, with significant effect,
And environmental protection.
Embodiment
Embodiment 1：A kind of concrete slump retaining agent, each material is prepared from by following percentage by weight：HPEG：30%, third
Olefin(e) acid：0.5%, hydrogen peroxide：0.07%, mercaptopropionic acid：0.022%, ascorbic acid：0.008%, acrylic acid hydroxyl ester：2.2%, hydroxide
Sodium：0.2%, water：67%.
Embodiment 2：A kind of concrete slump retaining agent, each material is prepared from by following percentage by weight：HPEG：35%, third
