Research ArticleOpen accessIn the keywordsInfluence of Cement Chemistry on the Performance of Cement Stabilized Tropical Lateritic SoilOdumade Adegboyega Oduniyi, Ezeah Chukwunonye, Charles Nnamdi Ezugwu, Ekeoma EmmanuelChemical composition affects overall performance of cement on other materials such as when used in concrete or for stabilization of lateritic soil. This research studied the influence of chemical composition of three Portland cement types represented as samples A, B and C on engineering performance when mixed with laterite under tropical environmental conditions.The Lateritic soil sample classified according to AASHTO … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 May 2018 · 8,804 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,761 accessesView PDF Cite
