Application And Research Of Concrete Mixing Ratio Optimization Design Technology

With the rapid development of China's modern economy and the process of reform and opening up,the scale of modern engineering construction is increasing and accelerating,how to ensure the quality and safety of construction projects while ensuring long-term safety of the project,engineering quality and safety accidents are usually Bring a major lesson,the quality of the project is the focus of attention of all sectors of the community.In modern engineering construction,especially in modern infrastructure,concrete is the most widely used building materials,and is now an indispensable building material in engineering construction.This paper briefly describes the research situation and development direction of concrete mix and optimization design in China and abroad,and puts forward the topic of this thesis according to the needs of this project.We use the principle of design of ordinary concrete in general concrete mix design As the theoretical basis,and according to the concrete mix design steps to design the research process and the corresponding operational guidelines,in the course of the study of the current engineering commonly used concrete and its influencing factors as our focus on the study.In this experiment,two optimization schemes were selected.The first optimization scheme was optimized from the concrete water content optimization,the optimization of fly ash content,the optimization of aggregate and the determination of water-cement ratio.The second optimization scheme was used to optimize the concrete mix ratio from the selection of different admixtures,the admixture of admixture and the combination of fly ash.At the same time,the influence of the quality of concrete on the quality of concrete is also analyzed.The influence of the quality of the raw material and the quality of the original material on the quality of the concrete is studied respectively.Finally,according to the optimization results of this subject,the practical application of the multi-group mix design of the actual project of Shaoguan power plant is optimized,the optimization effect is obvious,and the good economic benefit is achieved.
