when geotechnical engineers are faced with cohesive clayey soils, the engineering properties of those soils may need to be improved to make them suitable for construction. the aim of this paper is to study the effect of using lime, natural pozzolana or a combination of both on the geotechnical characteristics of two cohesive soils. lime or natural pozzolana were added to these soils at ranges o...

The objective of this study is to examine the effect of substitution of cement by three different mineral additions, on the mortar rheological and mechanical properties. This experimentation, considers the fineness of mineral additives with a constant workability. Ordinary Portland Cement was partially replaced by different percentages of slag, pozzolana and metakaolin of 10, 20 and 30%. The ob...

Portland Pozzolana Cement (PPC) is prepared by adding Pozzolanic materials to ordinary Cement. The artificial pozzolana used in the manufacturing of PPC such as fly ash, silica fume, rice husk, blast furnace slag, are actually industrial waste, which produced large amounts. These when concrete can reduce consumption natural resources, diminish effect pollutants environment and it economical rel...

with considerable dispersion in many areas of the world sediments are among the most important sediments in deserted environments. a stabilization method for this type of beds is making use of the setting property of natural pozzolana in the vicinity of lime. these soils have little strength, both in natural humidity as well as in full saturation conditions. their dispersion in many areas of th...
