Effect of the Fineness of Artificial Pozzolana (Sarooj) on the Properties of Lime-Pozzolana Mixes
Sultan Qaboos University Journal for Science, 2002 Strength development of lime-pozzolana mortars is affected by the fineness of the pozzolan. This paper examines the effect of the fineness of artificial pozzolana on the strength development of lime-pozzolana mixtures. An artificial pozzolana produced by

Modeling the Cementitious Effect of the Pozzolana on the Compressive Strength of Concrete
Cogent Engineering, 2018 The natural Pozzolana is a siliceous material (SiO2) that reacts with the calcium hydroxide Ca(OH)2 produced during the hydration period of the cement; this inherent feature increases the cementitious property of the grout and improves the compressive ...
