1. Effect of cement temperature on concrete quality
In summer and autumn, the temperature of cement is high, the water content is low, the hydration is fast, the heat of hydration is high, and the water demand is large. Therefore, when used in mortar or concrete, the work performance will be significantly reduced, the adaptability of admixtures will become poor, the concrete slump will lose quickly, and sometimes false setting and rapid setting will occur.
2. Effect of fly ash fineness on concrete quality
The fineness of fly ash is an important performance index of fly ash. If the concrete mix ratio is not adjusted according to the properties of raw materials, the performance of concrete will fluctuate greatly, and even the quality will be unqualified, which will seriously affect the stability of concrete.
3. Effect of superplasticizer on concrete quality
Different types of high-efficiency superplasticizers will have a greater impact on the performance of concrete, and the variety of superplasticizers will also have a great impact on the stability of concrete performance, especially in the fierce competition in the admixture industry. , The product quality and type of admixture should cause us to highly reproduce, in order to ensure the stability of concrete performance.
