    Abstract: To an unhardened concrete containing at least a cement, an aggregate and water, an alkali silicate is added in a weight ratio of from 0.2% to 5.0%, preferably from 0.2% to 2.0%, with respect to the cement on a solid content basis. The concrete containing the alkali silicate is placed into formwork as a temporary structure that confines the concrete to a predetermined shape and predetermined dimensions and supports the concrete until it attains suitable strength, thereby constructing a concrete structure. The amount of formwork materials used is reduced, and the operating efficiency and the physical properties of the concrete are improved.
