EN CEM II/B-P has potential advantages over CEM I when used to produce concrete. Incorporation of natural pozzolana reduces the amount of clinker used in cement production, hence raw materials, CO2 emission, and energy demand. Moreover, the pozzolana reacts with Ca(OH)2 produced by the hydration of Portland cement thereby mitigating alkali-aggregate reactions, destructive reactions with sulfates and acids, and carbonation shrinkage. In addition, additional C-S-H from the reaction of pozzolana and Ca(OH)2 increases long term strength and densification of the pore structure leading to improved durability. This research explores the effect of selected superplasticizers in the production of free-flowing concrete with CEM II/B-P 32.5N targeting high strength. Cube crushing strength above 60 MPa was obtained at 28 days, together with high initial flowability. However, workability reduced rapidly leading to stiffening within 30 minutes. Such concrete would not allow sufficient time for transportation, placement, and finishing, and therefore has limited application.
High performance, workability retention.
