粉煤灰影响系数值选取的相关因素研究

Research on Related factors of choose fly ash Influence coefficient

粉煤灰在不同胶凝材料用量条件下的活性系数不同,在配合比计算时,粉煤灰影响系数的取值范围也不同。通过试验确定不同胶材用量和不同掺量条件下粉煤灰的活性系数,为确定粉煤灰影响系数的取值范围提供依据,并提出长龄期评定的混凝土配合比计算时,可以适当提高粉煤灰影响系数的取值。以更有利于粉煤灰在混凝土中的大量使用。

Different activity coefficient of fly ash under different quantity of cementing materials. In mix proportion alculation, the scope of influence coefficient of fly ash is also different. The test to determine the different activity coefficient of fly ash under the condition of different a proportion and different quantity of cementing materials, provide the basis for determining the scope of fly ash Influence coefficient, and puts forward evaluation of long age concrete proportion computation, which can raise the value of fly ash influence coefficient and is more conducive to the extensive use of fly ash in concrete.
