The invention discloses a method for shortening the concrete curing period. The method comprises the following steps that standard strength and measured strength are obtained and then compared, and the shortened concrete curing period is obtained. Concrete obtained by means of the above method comprises the following components: by fraction, 12-20 fractions of water,15-25 fractions of cement, 7-15fractions of coal ash, 7-15 fractions of mineral powder, 50-100 fractions of sand, 70-120 fractions of stone and 0.5-1.2 fractions of water reducing agent. A manufacturing method of the concrete comprises the following steps of uniform mixing, dense molding and curing and hardening. By means of the method for shortening the concrete curing period, a method of boiling with clear water is adopted,so that the curing period can be significantly shortened, and the manufacturing process and strength measurement process of the concrete are simplified, so that the manufacturing cycle of the concreteis shortened, and the factory efficiency is improved; and the 28-day strength value under the standard can be obtained through the intuitive array data, compared with strength value obtaining througha concrete strength relationship, the method for shortening the concrete curing period can reduce a lot of calculation and statistics, and convenience and fastness are achieved.
