Title:
METHOD FOR RAPIDLY OPTIMIZING MIX PROPORTION OF PRECAST CONCRETE COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2023/206692
Kind Code:
A1
Abstract:
A method for rapidly optimizing the mix proportion of precast concrete components, comprising: determining a concrete 28d design strength and a concrete design strength at the conclusion of a rapid precast curing process which a precast concrete component must achieve; pre-determining a mix proportion of concrete, and preparing two groups of concrete specimens according to the mix proportion; curing the concrete specimens by means of an actual rapid precast curing method and a constant-temperature rapid curing means, measuring the strengths of the concrete specimens by means of a standard testing method after curing, and comparing the measured strengths with the required design strength, until the requirement is met. The present method may significantly reduce the number of trial mix attempts required to determine a concrete mix proportion, thereby speeding up the production progress of precast components, shortening the test mix cycle for the concrete, and reducing the reliance on engineering experience when adjusting the concrete mix proportion.
