Research: Peanut Pod Ashes as a Substitute of Sand in Concrete Hollow Block
The study Peanut Pod Ashes as a Substitute of Sand in Concrete Hollow Block aimed to find out the feasibility of peanut pod ashes as a substitute of sand in making concrete hollow blocks. Sand is mostly compose of quartz and quartz is mainly made up of Silica. Silica promotes hardening in concrete mixture. Burnt residue of peanut pods consists principally of sodium carbonate, potassium carbonate and silica.
To determine to feasibility of peanut pod ashes as a partial sand substitute, 5 kind of concrete hollow blocks were made. Each contained cement, water, and different ratios of sand is to peanut pod ashes. In preparing the peanut pod ashes, the peanuts were removed from their shells. Then, they were left to dry under the sun until the moisture in the peanut pods were gone. After that, the peanut pods were then burned. A metal container, a wooden stick ang denatured alcohol were used in the process of burning the peanut pods. The peanut pods were burned until they became ashes. Different mixtures of sand and peanut pod ashes were then prepared. The different mixtures were: 100% peanut pod ashes and 0% sand with 5 L of peanut pod ashes; 75% peanut pod ashes and 25% sand with 3.75 L of peanut pod ashes and 1.25 L of sand; 50% peanut pod ashes and 50% sand with 2.5 L of peanut pod ashes and 2.5 L of sand; 25% peanut pod ashes and 75% sand with 1.25 L of peanut pod ashes and 3.75 L of sand, and 0% peanut pod ashes; 100% sand with 5 L of sand. Water ang 5 L of cement were mixed to each of the mixtures. Then, the mixtures were placed in a mold with a volume of 630 cubic milliliters. After that, they were labeled and left to dry for at least 7 days. The compressive strength of the different hollow blocks were then acquired using a machine.
From the data obtained in this study, the compressive strength of the concrete hollow block with 0% peanut pod ashes and 100% sand was 270 psi; with 25% peanut pods’ ashes and 75% sand was 785 psi; with 50% peanut pods’ ashes and 50% sand was 250 psi. The two concrete hollow blocks which had 75% peanut pods’ ashes and 25% sand, and 100% peanut pods’ ashes and 0% sand were not formed. The concrete hollow block with the greatest compressive strength was the one with 25% peanut pods’ ashes and 75% sand. It had a compressive strength of 785 psi. From the findings, it can be concluded that burnt peanut pods may be a cheap sand substitute in making concrete hollow block as shown in the results of the compressive strength of the concrete hollow block with 25% peanut pods’ ashes and 75% sand. It had a compressive strength of 785 psi. Combining a little amount of peanut pod ashes with the mixture of the concrete hollow block may strengthen the concrete hollow block. The reason may be that peanut pod ashes occupy the spaces that sand cannot occupy due to the size of its particles. However, adding an amount of peanut pod ashes greater than the amount of sand may weaken the concrete hollow block. The silica content of peanut pod ashes may not be sufficient to hold all the different particles of the mixture together.
