Abstracts: There is need to economize the use of cement. One of the practical solutions to economize cement is to replace cement with supplementary cementations materials like corn cob ash, coal fly ash (aka pulverized fuel ash or PFA), GGBS, silica fume, metakaolin, rice husk ash, palm kernel shell ash. There had been various research efforts on the use of corn cob ash (CCA) and other pozzolan as a replacement for cement in concrete considered mixing of the CCA with Ordinary Portland cement at the point of need (i.e. on site) studied the workability and compressive strength characteristics of Corn cob ash (CCA) blended cement concrete.
