Compressive strength of geopolymer concrete is dependent on various components that formed the concrete, and the curing regime. This paper is the outcome of a review of various variables (components and relationships) that influence the compressive strength of (GPC). The variables identified from the literature are; Concentration (Molarity) of the Hydroxide solution, Alkaline Liquid/Geopolymer Solids (Liquid/Binder) ratio, Sodium silicate to Sodium hydroxide ratio (SS/SH), curing time, curing temperature, Water/Geopolymer Solids ratio, age, fineness of the binder (pozzolan), rest period, admixtures and aggregates. A careful examination of the influence of each variable on compressive strength revealed that Hydroxide concentration, SS/SH, curing temperature, Alkaline Liquid/Geopolymer Solid ratio and Water/Geopolymer Solid ratio are the major d...

This research examined the suitability of ternary blends of pulverized cow bone ash and waste glass powder (PCBAWGP) equally combined and partially replaced Portland cement in 0, 10, 20, 30 and 40 % percentages in concrete production. Physical and chemical properties were done on the concrete constituent materials. Compressive and tensile strengths of the hardened concrete of grade M20, mix proportion 1:2.17:3.4 were tested after 7, 14, 28, 60 and 90 days. The result of the physical properties uncovered that PCBAWGP had 2.70, 2.05 % and 1364 kg/m3 for specific gravity, moisture content and bulk density, respectively. From the consequences of the compressive strength, it showed that as the curing age of the concrete increases, the compressive strength expanded, the compressive stren...

Three samples of lateritic soil, named samples A, B, and C, were gathered from Idita-Mokuro, NTA-Mokuro, and ETF burrow pits, respectively, in Ile-Ife, Osun State, Nigeria. Preliminary tests were completed on the samples in their natural states and when stabilized with optimum lime. Engineering properties were performed while 2, 4, and 6 % GSA contents were added to the soil samples at optimum lime. The Atterberg limit tests showed a significant reduction in the plasticity index for samples A and C when stabilized with lime. Compaction test showed a decrease in the maximum dry density from 1,685 to 1,590 kg/m3 for sample A, 1,599 to 1,512 kg/m3 for sample B, and 1,396 to 1,270 kg/m3 for sample C on stabilizing with lime; the introduction of GSA to stabilized lime soil diminished the maximum dry density for all the soil samples, with sample A reduced to ...

Three site locations of lateritic soil named specimen I, II and III were assembled from Ifewara, Atakunmosa West Local Government Area, Ilesa East Local Government Area, and Ilesa West Local Government, all situated in Osun State, Nigeria. Preliminary tests were wrapped up on the soil specimens in their characteristic states and when stabilized with optimum lime. Compaction, California Bearing Ratio (CBR) and undrained triaxial shear strength tests were performed when fluctuating paces of 2 %, 4 %, 6 %, and 8 % of GSA were included to the soil specimens at optimum lime. The Atterberg limits tests showed a critical decrease in plasticity index for all the soil specimens when stabilized with lime. Compaction test showed a lessening in the maximum dry density from 1732 kg/m3 to 1651 kg/m3 for specimen I, 1874 kg/m3 to 1621 kg/m3 for specimen II and 1683 kg/m3 to 16...

Soil samples were collected at depths ranging from 0.25 to 1.5 meters from two different pits dug inside the premises of Federal University Oye Ekiti, Ikole Campus. Preliminary tests were performed on the soil samples in their natural states and when stabilized with varying percentage of cement. Pulverized Cow Bone Ash and Waste Glass (PCBAWG) in the ratio 1:1 were introduced to the soil in varying proportions of 2 %, 4 %, 6 %, 8 % and 10 % along with optimum cement by weight of the soil sample. The strength index of the soil was assessed by examining the maximum dry density, optimum moisture content and the California Bearing Ratio (CBR) of the soil as well as the shear stress. The results of the preliminary investigation revealed the soil samples according AASHTO soil grouping; as A-2-4 lateri...
