“…It was noted in a previous study by Kamau and Ahmed (2017) that the use of corncob ash in concrete demonstrated compressive strengths that were capable of being used for structural concrete. Price et al (2014) indicated that up to 10% replacement of CCA could be used in cement production without compromising the structural integrity. Reported studies indicated varying optimum CCA replacement of 10% (Price et al, 2014), 8% (Adesanya and Raheem, 2008), and 6.43% (Bagcal and Baccay, 2019), which could be utilized having compressive strengths capable of use for structural purposes.…”

The increasing demand in cement has inspired researchers in both developed and developing countries around the world to explore and consider alternative materials as partial replacement of cement both in concrete and in mortar. In this study, the influence of agricultural waste, particularly corn cob ash, (CCA) as pozzolanic material or supplementary cementitious material (SCM) on the physical properties and compressive strength of cement mortar was investigated. CCA was used as partial replacement of cement ranging from 0% to 20% by weight at water-cementitious ratio of 0.6 and mix proportion of 1 cementitious: 3 fillers. The physical properties evaluated for the mortar paste were setting time and consistency; and compressive strength of hardened mortar cube. The chemical analysis of CCA was conducted, and results indicated that the CCA used in this study is classified as Class C pozzolana with combined SiO2 + Al2O3 + Fe2O3 of 55.86%. The addition of CCA increases the initial and final setting time. The study also revealed that the addition of CCA in the mortar mix reduces the plasticity or fluidity of the paste. Further, the result indicated that the compressive strength of mortars with CCA decreased as the amount of CCA replacements increased in the mixture. The mortar pastes with varying amount of cement replacements, however, are superior for use as mortar for masonry construction.

“…This, therefore, forms the objective of this research through the adaptation of interlocking masonry and incorporation of low carbon footprint (corncob ash). In an attempt to reduce the negative impact of cement in building construction and partially replace it with corncob ash, this study thus, limits the cement content to 3% against the 5% content recommended by the Nigerian Building and Road Research Institute 2006, and substitute the remaining 2% with CCA at 5%, 10%, 15%, and 20% because the percentage replacement of PLC with CCA for use in structural applications with an impressive compressive strength according to Price et al (2014) and Kamau et al (2016) can be up to 15% and 25% respectively. Mechanical means of vibration was adopted and the sprinkling method of curing was employed.…”

The increase in carbon dioxide emissions due to cement manufacturing and improper disposal of corncob leads to environmental pollution and agricultural wastage respectively. This study investigates the use of corncob ash (CCA) as cement additive in producing lateritic interlocking blocks (LIB). Portland limestone cement (PLC) was replaced by CCA in varying percentages 5, 10, 15 and 20%. Effect of CCA on compressive strength and water absorption were determined and compared with the Nigerian standard requirements. The experimental findings showed that 3% PLC, 15% CCA with a compressive strength of 4.49MPa and water absorption of 6% at 28 days curing met the recommendations of both the Nigerian Building and Road Research Institute and the Nigerian Industrial Standards. Recycling of S.O. Oyebisi et al. CCA as a promising raw material supplement appears to be a viable solution not only to the environmental problem but also to the problem of adopting indigenous waste material in the production of LIB.

“…Consequently, the use of superplasticizers will be required to enhance workability. Price et al [8] reported that replacing a portion of ordinary portland cement (OPC) with up to 10 % CCA or MCA increased the compressive strength, enhanced insulation performance and workability time.…”

“…Recycling materials that otherwise would be treated as waste can create endless sustainable construction opportunities [8]. The main objectives of this study are to determine the pozzolanic activity of these plant ashes, their respective compressive strengths, and the optimum cement replacement that gives maximum strength concrete that can enable such blended concretes to used in construction works to reduce environmental degradation associated with mining materials for cement manufacture.…”
