“…A great many huge amounts of these wastes are created every day, industrial, domestic and agrarian waste takes an enormous level of these strong waste. Prominent materials, from solid wastes that have been utilized or discovered by scientists to be appropriate as partial replacement for constituent materials in concrete production incorporates: Glass powder [7]; waste glass [8]; pulverized bone [9,10]; rice husk ash [11][12][13]; plantain peel ash [14]; bone ash powder [15,16]; waste oil palm shells [17]; palm kernel shell [18]; periwinkle shell [19,20]; pulverized snail shell [21,22]; sea shells ash [23]; cassava starch [24]; bamboo leaf ash [25,26]; banana leaf powder [27]; groundnut shell ash [28,29]; and machine crushed animal bones [30]. These materials are either utilized independently or in blend, and for various concrete mix.…”

The amounts of agricultural waste in cow bone and industrial waste glass in Nigeria have been expanding significantly, thereby increasing the danger to general wellbeing particularly in urban communities. 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 strength outcomes at 10 % PCBAWGP partially replaced concrete is 15.55, 24.15, 19.85, 27.60 and 37.98 N/mm2 individually at 7, 14, 28, 60 and 90 days. At 90 days curing age, the tensile strength results for the control mix and 20 % PCBAWGP replacement was 2.72 and 1.88 N/mm2, respectively. The concrete strengths improved with concrete age and this was statistically affirmed utilizing ANOVA. This investigation showed that utilizing PCBAWGP in concrete is sustainable thereby reducing the dumped wastes and lessen CO2 outflows into the atmosphere by diminishing the extent of Portland cement in unit volume of cement produced. HIGHLIGHTS The compressive strength of concrete reduces as % pulverized cow bone ash and waste glass powder PCBAWGP increases. The compressive strength generally increases with increase in age of curing. The minimum and maximum compressive strength of concrete at 10 and 40 % PCBAWGP content for 1:2.17:3.4 concrete mix ratio at 28- and 90-days curing age are 19.85, 37.98 N/mm2 and 15.68, 22.31 N/mm2, respectively The minimum and maximum tensile strength of concrete at 10 and 40 % PCBAWGP at 28- and 90-days curing age are 1.71, 2.19 N/mm2 and 0.70, 1.55 N/mm, respectively The result of the water absorption tests at 28 days and 90 days showed that concrete samples containing PCBAWGP built up a superior protection from harm by freezing as their outcomes were less than 7 % recommendation Concrete containing PCBAWGP contents up to 20 % as partial replacement for cement, fulfills the strength required for normal concrete From the production comparative cost analysis, concrete with PCBAWGP content, as partial substitution for cement, is cheaper than conventional concrete of equivalent strength GRAPHICAL ABSTRACT
