Method for shortening concrete curing period and application

Abstract

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.

Description

technical field [0001] The invention relates to a concrete maintenance method and application, in particular to a method and application for shortening the concrete maintenance period. Background technique [0002] According to the provisions of GB / T50081 "Test Methods for Mechanical Properties of Ordinary Concrete", the specimens with standard curing should be cured in a standard curing room with a temperature of 20±2°C and a relative humidity of more than 95%. The curing period is 28 days. Measure the strength of concrete. This measurement method has a serious time lag. For commercial concrete mixing plants, a large amount of concrete needs to be delivered every day, which is extremely unfavorable for concrete quality control. [0003] In the prior art, there is no good way to effectively shorten the curing cycle. The concrete still needs to go through a 28-day curing cycle before leaving the factory, which is not conducive to the timely detection and delivery of the conc...

This measurement method has serious time lag. For commercial concrete mixing plants, a large amount of concrete needs to be shipped every day, which is extremely unfavorable for concrete quality control.

[0003] In the prior art, there is no good way to effectively shorten the curing cycle. The concrete still needs to go through a 28-day curing cycle before leaving the factory, which is not conducive to the timely detection and delivery of concrete, which increases the production cost of the factory and reduces the production efficiency.
