Construction regulations of early strength agent and early strength water reducer in concrete engineering?

1, the inspection items of early strength agent and early strength water reducer entering the site (or concrete mixing station) should include density (or fineness), 1d, 3d compressive strength and corrosion effect on steel bars. The water reduction rate of early strength water reducer should be increased. If the concrete has a finishing requirement, it should also observe whether the surface of the concrete after hardening is disintegrating salt. Only after meeting the requirements can it be stored and used.

2, powder early strength agent and early strength water reducer directly into the concrete dry material should extend the mixing time 30s.

3. Concrete using early strength agent or early strength water reducer at normal temperature and low temperature should be covered with plastic film or sprayed with curing liquid when natural curing is used. After the final setting should be immediately watered and wet maintenance. When the minimum temperature is lower than 0℃, in addition to plastic film, insulation materials should be covered. Antifreeze should be used when the minimum temperature is below -5℃.

4. When concrete doped with early strength agent or early strength water reducer is steam cured, its steaming system should be determined by test.
