Abstract
In order to solve the bulk utilization of the fly ash, we studied the effects of compound activator on the strengths of cement with high volume fly ash and hydration mechanisms,improving the activity of fly ash,achieve the purpose of big dosage used preparation of fly ash. The results in-dicate that,the effects of compound activator is remarkable, the compressive and flexural strength of 3 days and 28 days achieved the 425 cement standards;The resulting ratio of fly ash cement ma-terials as follows:75% of fly ash,clinker 20%,gypsum 5%,compound activator 3%. The physi-cal properties of the fly ash cement materials with setting time,fluidity and soundness of mortar was also studied, and the results can meet international standards. It was found that the addition of compound can improve cementitious activity of the fly ash,and the cement with high volume fly ash may be utilized in industry.关键词
