Strength Characteristics of Mortar with Diatomite Powder as an Admixture

Synthesis of cordierite powder from talc, diatomite and alumina

A cordierite powder was synthesized from a batch composition of talc, diatomite and alumina. Sintered samples of the synthesized cordierite were characterized by X-ray diffraction (XRD), differential thermal analysis (DTA), and Rietveld analysis. The XRD analysis showed hexagonal or a-cordierite (indialite) as a major phase along with MgAl2O4 spinel and cristobalite as secondary phases in the s...

Effects of Pozzolanic Admixture (Waste Bricks) on Mechanical Response of Mortar

This work presents an experimental study realized at the materials laboratory of the University of M’sila. It consists to vary the percentage of the pozzolanic admixture (waste bricks) in cement by the substitution method (partial replacement of the clinker by the calcined clay). The characteristics of cement at anhydrous state and the hydrated state (chemical composition, specific weight and f...

Characteristics of Ceramic Fiber Modified Asphalt Mortar

Ceramic fiber, with a major composition of Al₂O₃ and SiO₂, has advantages of stability at relatively high temperature, big specific surface area and resistance to external mechanical vibration. It has the potential contribution of improving the rutting resistance and temperature sensitivity of modified asphalt binder by proper modification design. In this research, ceramic fiber was introduced ...
