本文通过大量试验及实践生产对比单掺粉煤灰与复掺技术配制的商品混凝土性能。建议实际应用中可以采用矿粉—粉煤灰复掺技术,充分发挥矿粉和粉煤灰的互补效应,改善混凝土的和易性、耐久性和可泵性,保护环境,降低企业的生产成本,提高企业的竞争力。 In this paper, through a large number of experiments and practice of production compared with single mixed fly ash and mixed concrete technology formulated commercial concrete performance. It is suggested that the practical application of slag powder - fly ash complex doping technology, give full play to the complementary effects of slag and fly ash to improve the workability, durability and pumpability of concrete to protect the environment and reduce production costs , Improve the competitiveness of enterprises.
