[technical field] [0001] The invention relates to a control method for a concrete mix ratio optimization system. [Background technique] [0002] The multi-components of high-performance concrete mixture (including the four major components of ordinary concrete and the addition of mineral admixtures and admixtures) and its multi-performance indicators (in addition to the requirements for strength, but also for its fluidity, overall stability There are certain requirements for a variety of performances such as sex), which leads to the complexity of its mix ratio design, and the intelligent design of the mix ratio is very necessary. [0003] The significant difference between HPC and ordinary high-performance concrete is that it has more raw material components and more stringent performance requirements, and its mix ratio design has many influencing factors and quality control is also more complicated, which makes the mix ratio design consume more time.

[0003] The significant difference between HPC and ordinary high-performance concrete is that it has more raw material components and more stringent performance requirements, and its mix ratio design has many influencing factors and quality control is also more complicated, which makes the mix ratio design consume more time. manpower, material resources

[0004] There are many methods for the design of high-performance concrete mix proportions: experimental methods, semi-empirical and semi-experimental methods, and theoretical analysis methods, but these methods have one thing in common, that is, the trial mix of high-performance concrete must be carried out first, and then according to the results of the trial mix Then adjust the mix ratio, and finally determine the final mix ratio. High-performance concrete has significant regional characteristics, and the formulations of high-performance concrete in different regions are not consistent. Therefore, repeated trial mix work is required, which consumes a lot of manpower and material resources.

[0005] Furthermore, HPC is very sensitive to the performance of raw materials and the mix ratio, and the performance fluctuation is relatively large. The traditional mix ratio design method is difficult to meet the expected accuracy requirements

Due to the rapid development of modern high performance concrete structure and construction technology, the performance requirements of high performance concrete are developing in a variety of ways, but the factors affecting the performance of high performance concrete are complex and changeable (subject to production technology equipment, engineering design, construction conditions and experience, Non-linear effects of various factors such as regional differences in raw material performance), so that the characteristics of the high-performance concrete preparation mode are not clear, especially for high-performance concrete, and there is still no simple and feasible design of high-performance concrete mix ratio and its various The formula method of the performance index, the existing intelligent system of high performance concrete mix ratio, considers the performance is relatively simple, mainly to meet the requirements of strength and work performance
