The blended cement produced from the combination of Portland cement with ggbs can be manufactured by the intergrinding of the two components (i.e. clinker and granulated slag) in the ball mills or by blending the two components (i.e. PC and ggbs) as separate powers at the factory or by blending in the mixer. Intergrinding can lead to problems ...

Pozzolanic cement blends were prepared by the partial substitution of ordinary Portland cement (OPC) with different percentages of burnt clay (BC), Libyan clay fired at 700 °C, of 10, 20, and 30%. The pastes were made using an initial water/solid ratio of 0.30 by mass of each cement blend and hydrated for 1, 3, 7, 28, and 90 days. The pozzolanic OPC–BC blend …

Abstract. This study investigates the compressive strengths of mortar prisms of Portland pozzolana cement (PPC) samples prepared with 6.67–20.00% compositions of rice husk ash (RHA) as the pozzolanic constituents. CEN standard sand–cement, and pit sand-cement mortar prisms were separately prepared using cement-sand blend ratio 1:3.
