The overall production of the cement has greatly increased which results lots problems in environment as it involves emission CO2 gas. Environmental concerns, stemming from high energy expense and carbon dioxide associated with manufacture have brought about pressures to reduce consumption through use supplementary materials. Materials such Metakaolin, fly ash good pozzolanic activity are a mat...

The present study focuses on exploring the effects of reactivity and degree dispersion BaCO 3 additions in manufacture sulfate-resistant OPC cements. A new electrochemical deposition method is attempted to effectively disperse particles (studying two different materials with particle size: D 50 = 11.45 2.37 μm) cement enhance their favour sulfate immobilisation form BaSO 4 . barium carbonate ad...

Light weight concrete has many advantages that can be used in the construction of buildings. Perhaps one most important these features is its light weight, which contributes a lot to reducing stress on soil, provides possibility rising buildings and increasing number floors. In addition role thermal insulation impact consumption energy sources cooling heating, considered sustainability factors ...

Sulfate attack is potentially one of the most damaging forms of degradation affecting portland cement-based materials. However, despite over six decades of study, considerable uncertainty remains in optimally selecting and proportioning materials for sulfate resistance, and current understanding of the actual mechanisms of degradation in sulfate environments remains incomplete. In this research...

Clinker is the raw material used in manufacture of cement. However, this very harmful to environment, since it estimated that for every ton clinker produced, about 1.0 CO2 released into atmosphere. For reason, alternatives were sought use other materials are less environment. This has led industrial by-products with aim increasing their and thus reducing amount carbon Blast furnace slag a by-pr...

One of the growing demands in concrete manufacture is availability natural fine aggregates, which account for 35% to 45% total concrete. An alternative method disposal recycled aggregates (FRCA) generated from demolition and construction waste (C&DW) their usage mortar development mortar. The main aim this research work evaluate viability incorporating FRCA urban C&DW cement-based morta...
