Production process and mixing system for manufacturing high-strength clinker-reduced cement-clinker concrete using multi-source regional fly ash

Abstract

This useful solution refers to the production process and mix design for high-strength concrete that reduces clinker cement content, utilizing multiple sources of fly ash from various regions in Vietnam (Uong Bi, Duyen Hai, Thai Binh, Na Duong, Mao Khe, etc.) to produce high- and ultra-high-strength concrete with reduced clinker cement content. The mix design controls the maximum amount of PCB40 cement at 160 kg to 358 kg / m³, using fly ash accounting for 45% - 60% of the binder, combined with a superplasticizer additive.
