Optimization of Cement Replacement by Fly Ash in Compressive Strength of Portland Cement ConcreteBy Anil Kumar, Altaf Ahmad
Abstract: The production of cement has been known for its additive role in environmental pollution. As a measure of abatement of pollution effort, scientist have evoked the concept of diluting cement with various pozzolanic additive like fly ash, blast furnace slag etc. Many of these additives were found to be acceptable for cement replacement, but their exact role and efficacy remains elusive. In the present study, fly ash was added as …

Partial Replacement of Sand and Cement by Iron Ore Slime for Concrete Building MaterialBy Anil Kumar, Jyolsna Jerin, R.K. Rath
Abstract: Iron ore slime is a waste material generated after beneficiation of iron ores. It causes air, water and land pollution. From resource conservation point of view, the recovery of iron values is important and their use in different application. Researchers are also trying to find out value-added alternative application of iron ore slime rejects. In this paper, iron ore slime was used in concrete building material and evaluated the partial …

Review of Nitrite Inhibitor for Protection of Rebar CorrosionBy Anil Kumar, Altaf Ahmad
Abstract: Load bearing concrete structures need steel reinforcement (rebar) strips or rods, which are prone to attack by the corrosive environment inside the concrete due to constant ingress of moisture, pollutant gases and anions (mainly Cl-, SO4- -). One of the means of reducing such type of corrosion is the use of inhibitors. Inhibitors are water soluble but film forming on metals by their selective adsorption on the metal surface. These …
