“…The partial replacement of cement with CBA is anticipated to reduce the quantity of Ca(OH) 2 due to its chemical composition. Additionally, CBA typically contains a high concentration of calcium oxide (CaO) (Getahun & Bewket, 2021;Okeyinka et al, 2018).…”

The research investigated the impact of cowbone ash blended cement concrete (CBABC) on compressive strength, considering various mix ratios and curing periods. The study involved several phases: production of cowbone ash (CBA) from waste cowbones, characterization of CBA's physical and chemical properties, and formulation of CBABC mixes with 0%, 5%, and 10% CBA as partial replacements of cement. Concrete samples were prepared at ratios of 1:2:4 and 1:3:6 and cured for 7, 14, and 28 days. Cubic CBAC specimens sized 100mm by 100mm by 100mm underwent testing for compressive strength under both aggressive and non-aggressive conditions after 7, 14 and 28-days curing period. Analysis of oxide composition revealed a high calcium oxide content in CBA, constituting 68.34% by weight. With increasing CBA proportion, CBAC mixes showed enhanced workability. Under water curing at 28 days curing conditions, CBAC concrete exhibited average compressive strengths of 12.47 N/mm², 26.34 N/mm² and 20.34 N/mm² for 0%, 5% and 10% CBA content, respectively. Upon exposure to aggressive conditions, both conventional concrete (0% CBA) and CBABC concrete experienced decreased compressive strength. Notably, the CBABC mix with 5% CBA displayed greater resistance to aggressive conditions compared to other mixes. In conclusion, CBABC with 5% CBA replacement demonstrates potential for application in aggressive environments, particularly in Sodium Sulphate (Na2SO4), offering a durable alternative to conventional Grade C25 concrete mixes.

“…For calcium oxide, most of the studies showed that the use of materials that contain high contents of calcium can improve the mechanical properties of concrete [16][17][18][19]. Counterversy, other researchers showed that materials containing calcium oxides can negatively affect the compressive strength of concrete when added to the concrete mixes [20,21].…”

In this study, the effect of using cattle bone ash (CBA) and waste glass powder (WGP) on the mechanical properties of mortar and concrete is investigated. The two materials were chosen because one of them is a source of silica oxide and the other one is a source of calcium oxide; where these two oxides are the main constituents of ordinary cement. The two materials were used as additives to the mortar/concrete mixtures. For (CBA), the powder was added to the mortar/concrete mixtures as percentages of the cement by weight .The percentages used were 0%, 1%, 3%, 5%, and 7% by weight. Like the CBA, (WGP) was added to the mortar/ concrete in the percentages of 0%, 1%, 3%, 5%, 7% and 10% of the cement weight. Atomic absorption spectroscopy analysis test was conducted on CBA, while XRF analysis was conducted on WGP to obtain the chemical composition of each material . A total number of 150 cube specimens were tested in the experimental program and the results showed that both materials are beneficial to mortar and concrete mixtures from the compressive strength perspective. The results showed that the CBA has significant effect in the early ages of concrete while WGP has significant effect on the long term.
