摘要
超早强混凝土的研制经历了从单一早强剂到复合早强剂、再由复合早强剂与高强快硬水泥相结合的发展阶段.高效减水泵送剂、复合早强剂、高强快硬水泥配制的超强早强C30混凝土,24h能达到近20MPa的强度,以达到精轧机尽快投产的效果.
The development of super early strength concrete has went through several phases such as single early strength agent, compound early strength admixture, combined compound early strength admixture with fast hardening and high strength cement. The strength is up to 20MPa in 24 hours by using high efficiency water reducing agent, compound early strength admixture, super strength and early strength concrete C30 made of fast hardening and high strength cement. Thus the finishing rolling mill can put into production as soon as possible.
