Description

technical field [0001] The invention relates to the technical field of concrete proportioning optimization, and more particularly, to a method and system for optimizing the proportioning of ultra-early strength concrete based on high-dimensional multi-objective optimization. Background technique [0002] Super early-strength concrete is a kind of special concrete. It adds admixtures on the basis of ordinary concrete formula to accelerate the chemical reaction, so that the concrete can reach a certain strength in the shortest time to meet the needs of engineering. It is generally believed that when the 1-day strength of concrete is greater than 50% of the design strength grade, and the 3-day strength reaches 90% to 100% of the design strength grade, which shortens the maturity period of concrete from 28 days to 3 days, it is regarded as super-early strength concrete. Super early-strength concrete has broad application prospects in the maintenance of highways, bridges, seaport...
