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

Sulphate resistance of type V cements with limestone filler and natural pozzolana
Cement and Concrete Composites, 2000Sulphate 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.

Hygric Properties of HPC with Natural Pozzolana
Key Engineering Materials, 2016The water vapour transport and the liquid water transport of high performance concrete (HPC) with the content of natural pozzolana are the described in this paper. Studied properties are presented by means of water vapour diffusion coefficient, water vapour diffusion resistance factor and absorption coefficient respectively. The natural pozzolana (NP),

Lime mortar with natural pozzolana
2008The paper deals with the investigation of the mechanical behavior of lime mortar enriched with natural pozzolana, widely used in historical masonry. The study aims to investigate the mechanical behavior of natural pozzolana lime mortars, reproduced in laboratory by using different mix designs, as reported in historical Italian architectural treatises ...

Use of Natural Pozzolana and Lime for Stabilization of Cohesive Soils
Geotechnical and Geological Engineering, 2011The present study investigates the use of natural pozzolana combined with lime for ground improvement applications. Laboratory tests were undertaken to study the effect of natural pozzolana, lime or a combination of both on the physical and the mechanical characteristics of cohesive soils.

Physical effects of natural pozzolana on alkali-activated slag cement
World Journal of Engineering, 2011The alkali-activated slag (AAS) cement is an interesting building material, confronting to the new economical and ecological challenges. In order to enhance its physical properties in comparison with ordinary Portland cement (OPC), we used natural pozzolana as a mineral addition.
