“…Table 4 shows the LOI values proving there was a ) is found to be less than the minimum of 70% specified for pozzolanas by [27] to characterize as class N and class F. e chemical oxide compositions obtained were confirmed with the oxide's compositions reported by Ndefo [53], Nwofor and Sule [52], and Rathod and Mahure [54]. However, in the case of Usman et al [50] and Buari et al [51], the percentage content of sulfur trioxide was found to be much lower than the maximum recommended (5%). Different studies have shown that silica, alumina, and iron oxide are the main chemical oxides of rice husk ash (RHA).…”

A contrast GNA amount of oxides was investigated by Nwofor and Sule [52].…”

The main goal of this review paper was to study the physical and chemical properties of agricultural crop wastes and their potentials to partially replace in production of mortar and concrete. Bamboo leaves’ ashes (BLA), banana leaves’ ashes (BNLA), corncob leaves’ ashes (CCA), groundnut ashes (GNA), rice husk ashes (RHA), and sugarcane bagasse ashes (SCBA) were selected to be reviewed. The chemical composition of these agricultural wastes revealed that the they are basically composed of alumino-siliceous materials conforming the requirement of pozzolanic materials. Compared with cement, they have finer particle size and higher surface area. The effect of partial replacement of cement by BLA, BNLA, CCA, GNA, RHA, and SCBA on the properties of fresh concrete (consistency, workability, and setting time), mechanical properties (compressive and tensile strength), microstructure (scanning electron microscopy, derivative thermogravimetry, and X-ray diffraction), and durability (ultrapulse velocity, water absorption, and sulphate attack) of concrete was recapped. The inclusion of BLA, CCA, RHA, and SCBA as partial replacement of cement reduced the workability of concrete due to their finer particle size. The mechanical performance of concrete showed enhancement with partial replacement of cement by BLA, RHA, and SCBA due to the involvement of amorphous silica in secondary reaction to produce densified tetrahedral gel. Consequently, uniform and denser morphology was formed, and durability was enhanced as densification of hydrated gel increased. In general, the review exposed that agricultural crop wastes satisfy pozzolanic material properties and have strong potential to replace cement up to 10% without compromising the performance of concrete.

“…The peak compressive strength and flexural strength for the 10.00 percent CA + 20.00 percent GSA + 10.00 percent FA sample were 34.90 N/mm 2 and 5.90 N/mm 2 , respectively, which was an 8.20 percentage and 4.00 % increase in strength over the control sample. Kumari etc., [17] used (RHA) and GSA 2.51-12.51 percent to substitute cement in concrete. Slump decreased by 35.60 percent as the replacement quantity in the mixture was increased to 12.55 percent, and densities decreased from 2370 kg per m 3 to 2235 kg per m 3 .…”

The construction industry will have an increasing problem in meeting increased demand, and production of construction materials such as bricks, concrete, mortar and steel will expand. Agricultural businesses, on the other hand, generate massive amounts of residues each year all throughout the world, posing concerns about the environment because the majority of these wastes are either burnt or dumped in landfills. Many agricultural waste materials Agricultural waste products have already been employed in a variety of applications such as in concrete, mortar as aggregate, or binding material substitutes. This review examines the use of groundnut shell ash in the manufacture of bricks, cement mortar, and cement concrete. various qualities of bricks, concrete, cement mortar when groundnut shell ashes are added with these materials are examined, and criteria that are related to various standards are compared. Because majority of the created materials meet the specifications, the analysis of literature revealed a visible potential for ground nut shell ash as a Substitution of a portion for materials that are commonly used. However, there is a dearth of research on durability and thermal qualities. Furthermore, existing research is insufficient to determine the wastes' potential for reuse in the manufacture of construction materials. As a result, substantial study is required to reinforce current knowledge in this subject in order to meet long-term objectives in the building business.

“…Apart from CO2 emissions in cement production, the use of GSA has benefits such as less cement use, reduction in concrete production costs; reduces environmental pollution and improvement of the durability properties of the concrete. Many Researches have proven that GSA blended concretes are of better strength with better elasticity and minimal water absorption's [3,4,5]. The use of GSA as SCM in SCHPC can greatly enhance the workability, durability and aesthetic appeal of the concrete.…”

This experimental work evaluates the relationship between compressive strength and modulus of Elasticity of self-consolidating High performance concrete (SCHPC) containing high volume of Groundnut Shell Ash (GSA) up to 40% substitution as SCM. A total of 210 specimens of the GSA blended SCHPCs comprising 105 cubes (100 x100 mm) and 105 cylinders (150x300 mm) were cured in water for 7,14,28 ,56, 92,120 and 180 days hydration periods and the compressive strength and Modulus of elasticity determined. The linear relationships were studied with regression analysis. The findings revealed that all the mixes met the Modulus of Elasticity values requirement of 18,000N/mm2 to 42,000N/mm2 and the compressive results show that three substitution levels of 0%, 10% and 20% attained the proposed design strength (40-130 Mpa) and also satisfied the requirement for self-consolidating and high strength concretes. In conclusion, 0%-20% GSA substitutions (SCHPCA0-SCHPCA20) indicated a strong linear relationship with regressions values obtained varies between 0.842 and 0.954 for the two variables. Addition of GSA as SCM has improved the mechanical properties of SCHPC and creates a strong relationship between the compressive strength and Modulus of Elasticity.
