MIX PROPORTION AND PROPERTIES OF REPAIR MORTAR USING MAGNESIA-PHOSPHATE CEMENT

Solidification/Stabilization of Lead Contaminated Soil Using Magnesia Phosphate cement and Ordinary Portland cement

Background and objectives: Solidification/stabilization is an effective technique for reducing the leachability of contaminants in soils. Magnesia phosphate cement and ordinary Portland cement can be used to remediate soils contaminated. In this study, the performance of the solidified/stabilized soil was compared for mixtures composed of magnesia phosphate and ordinary Portland cement. Materia...

ThE EFFECT OF METAKOLIN, MICROSILICA AND NANOSILICA ON THE MECHANICAL PROPERTIES AND MICROSTRUCTURE OF CEMENT MORTAR

Different mineral admixtures of Indian metakaolin, Iranian silica fume and nanosilica were used to produce high performance mortars. Two different sands types with grain size of 0.015-4mm were mixed with type II Portland cement, polycarboxylate superplasticizer,mineral admixture with 650kg/m3 cement content and water/cement ratio of 0.35. Different amount of cement was replaced by metakaolin or...

Influence of (SBR) Latex and Silica Fume on Properties and Performance of Cement - based Repair Concretes

Influence of (SBR) Latex and Silica Fume on Properties and Performance of Cement - based Repair Concretes

Increasing flexural strength and toughness of cement mortar using multi-walled Carbon nanotubes

In this study the effect of using multi-walled carbon nanotube (MWCNT) on flexural and compressive strengths, ultimate displacement and energy absorption capability of standard cement mortar considering different weight percentages of nanotubes as well as different dispersion methods has been investigated. Influential point in adding nanotubes to the composites is their proper dispersion, which...
