The influence of material properties on concrete quality

With the increasing development of China's economy, the demand for concrete is gradually increasing, and the number of related enterprises is also rapidly increasing. Therefore, the stability of concrete performance is crucial!

The stability of concrete quality is most significantly affected by raw materials, and fluctuations in the quality of raw materials are objective and inevitable. Ensuring the quality of raw materials is fundamental to ensuring the quality of concrete. However, due to objective conditions such as continuous production and testing cycles, some raw materials with changes in performance and urgent need to be used must be adjusted in a timely manner based on apparent phenomena or performance indicators that can quickly yield results to reduce or avoid fluctuations in concrete quality.

1. The influence of cement temperature on concrete quality

In the summer and autumn seasons, cement has high temperature, low water content, fast hydration, high hydration heat, and high water demand. Therefore, when used in mortar or concrete, it will show a significant decrease in working performance, poor adaptability of admixtures, rapid loss of concrete slump, and sometimes even produce phenomena such as false setting and rapid setting.

2. The influence of fly ash fineness on concrete quality

The fineness of fly ash is an important performance indicator of fly ash. If the concrete mix ratio is not adjusted based on the performance of raw materials, it will cause significant fluctuations in the performance of the concrete, and even lead to substandard quality, seriously affecting the stability of the concrete.

3. The impact of high-efficiency water reducing agents on the quality of concrete

Different types of high-efficiency water reducing agents have a significant impact on the performance of concrete, and the variety of water reducing agents also has a significant impact on the stability of concrete performance, especially in the fiercely competitive and mixed environment of the admixture industry. The quality and type of admixture products should be highly reproducible to ensure the stability of concrete performance.
