Concrete mix proportion design method based on integration algorithm

Abstract

The invention provides a concrete mix proportion design method based on an integration algorithm, which is characterized by comprising the following steps: S1) preparing water, cement, a water reducing agent, sand and stones for preparing concrete according to the standard of Common Concrete mix proportion design Regulations; s2) determining designed concrete performance; s3) constructing a concrete performance ensemble learning first model according to the existing data; and S4) according to the first model, solving the optimal mix proportion by using the second model. The invention has the beneficial effects that the mix proportion design is optimized on the premise of satisfying the strength and fluidity of the concrete, and the cost of the concrete material is saved. And by fully utilizing the existing data, the experience requirements on experimenters are reduced, and the number of experiments is greatly reduced.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for designing concrete mix proportions based on an integrated algorithm. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, densely formed and cured . In concrete, sand and stone act as the skeleton, which is called aggregate; cement and water form cement slurry, which wraps on the surface of the aggregate and fills its gaps. Before hardening, the cement slurry acts as a lubricant, giving the mixture a certain Workability, easy construction, after the cement slurry hardens, the aggregate is cemented into a solid whole. [0003] The fluidity of concrete is generally expressed by slump, the greater the slump, the better the fluidity; the strength of concrete genera...

Problems solved by technology

[0004] The existing technology mainly has the following problems: ① Due to the large variation in the quality of raw materials such as concrete materials, sand and gravel, skilled technicians are usually required to conduct a large number of experiments, and the adjustment process depends on technology Personnel experience, the test results may not be the best value; ②Although the existing calculation theory can guarantee the strength, the fluidity may not be satisfactory, nor may it be the most economical; ③The theoretical calculation of serous film thickness or water film thickness, flow The performance is satisfactory, but the strength is not necessarily satisfied, nor is it necessarily the most economical
