Stabilization of Algerian Clayey Soils With Natural Pozzolana and Lime [PDF]
Periodica Polytechnica: Civil Engineering, 2017 Cohesive soils with a high plasticity index present difficulties in construction operations because they usually contain expansive clay minerals. However, the engineering properties of soils can be improved by different techniques. The aim of this paper is to study the effect of using lime, natural pozzolana or a combination of both lime and natural ...

Sulphate Resistance of Type V Cements With Limestone Filler and Natural Pozzolana
Cement and Concrete Composites, 2000 Sulphate performance of concrete depends primarily on permeability. Under severe conditions of sulphate exposure, low-permeability concrete is prescribed and it must also be made with high sulphate resisting cement. For portland cement, the sulphate resistance depends on the C3A content and the amount of CH produced at early stages of hydration.

Effect of Natural Pozzolana and Marble Powder on the Properties of Self-Compacting Concrete
Construction and Building Materials, 2012Abstract The objective of this investigation is to examine the effect of substitution of cement with natural pozzolana and marble powder on the rheological and mechanical properties of self-compacting mortar (SCM) and self compacting concrete (SCC). Ordinary Portland Cement (OPC) was partially replaced by different percentages of pozzolana and marble
