Experimental comparison of selected pozzolanic materials
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: K. A. Olonade --- Department of Civil Engineering, Nigeria M. B. Jaji --- Department of Civil Engineering, Nigeria O. A. Adekitan --- Department of Civil Engineering, NigeriaDifferent pozzolanic materials are commonly used in concrete production with different properties. This paper compared the performance of metakaoline (MTK), bamboo leaf ash (BLA), pulverized fly ash (PFA) and corn cob ash (CCA), when used as partial replacement for cement... -
Rice husk ash as a sustainable supplementary cementitious material for improved concrete properties
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Nsesheye Susan Msinjili --- Division 7.4 - Technology of Construction Materials, Germany Wolfram Schmidt --- Division 7.4 - Technology of Construction Materials, Germany Andreas Rogge --- Division 7.4 - Technology of Construction Materials, Germany Hans-Carsten Kühne --- Division 7.4 - Technology of Construction Materials, GermanyThere is a wide range of research worldwide on supplementary cementitious materials (SCMs) such as fly ash, slag and silica fumes that have pozzolanic properties sufficient for substituting ordinary Portland cement (OPC). These SCMs are known to significantly improve concrete...
