At least seven days. 7 days by car, 3~5 tons in half a month, 2 1 day by car. 2 1 day concrete curing is basically completed, which can reach the design strength. It takes half a month to reach the design strength with curing agent and 3~7 days with accelerator.

28 days in theory. In fact, there are seven days in spring and autumn and four days in summer (noon). If you can keep healthy, you can drive.

Concrete pouring: the construction process of pouring the mixed concrete into the warehouse, closing the warehouse, tamping and compacting. Pouring should be continuous and uniform to prevent concrete segregation.

The closed position is to spread the concrete evenly over the whole poured warehouse surface by manual or mechanical methods; Ramming compaction, also known as "vibrating", includes manual vibrating and mechanical vibrating, which is widely used in water conservancy projects.

When pouring ready-mixed concrete, a supply contract should be signed with the ready-mixed concrete supplier in advance, and the concrete quality must meet the requirements of the current national specifications and design documents, and the concrete quality should be strictly checked and accepted when entering the site.

Prepare sacks, curing felt or curing liquid for concrete curing.
