The prediction of strength of lime ash composites is critical for quality control, material performance monitoring and material serviceability limit state. A study was conducted to investigate the influence of open porosity (an index of micro grain alignm... see more

The effect of the incorporation of a petrochemical industry waste, named spent fluid catalytic cracking (FCC) in the hydration process and microstructure of cementpaste, was studied. Portland cement (OPC) pastes, with and without addition of meta-kaolin (... see more

The exciting features of carbon nanotubes (CNTs), such as high elastic modulus, high thermal and electrical conductivities, robustness, and nanoscopic surface properties make them attractive candidates for the cement industry. They have the potential to s... see more

Currently economical and environmental advantages of cement clinker replacement by other supplementary cementious materials are well known. For example calcined clays, such as metakaolin, have drawn special attention during recent years. It is well known ... see more

This study aims at comparing the hydration characteristics between two kinds of cements, the Portland slag cement (PSC) containing 50 wt.% ground granulated blast furnace slag (GGBFS), and the supersulfated cement (SSC) containing 85 wt.% GGBFS.... see more

The hydration properties of various cementitious materials containing Ground Granulated Blast-furnace Slag (GGBS), two alkali-activated slag cements (AAS-1 and AAS-2) in which sodium silicate and sodium hydroxide act as alkaline activators respectively, s... see more

The role of waste glass powder (GP) during the hydration process of composite cementitious materials was investigated by using mercury intrusion porosimetry (MIP), X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The compressive ... see more

AbstractThis article presents results of a research about the effect to incorporate Colombian volcanic materials as a replacement of ordinary Portland cement on its hydration process. For this particular case were used Tolima volcanic material (TVM) and P... see more
