Chicken (Gallus gallus domesticus) Egg Shells and Plastic Waste for Coarse Aggregate of Concrete Hollow Block

Abstract

INTRODUCTION

In today's generation, the use of concrete hollow blocks is very important. Hollow blocks are often used for construction. But through the years the price of hollow blocks have risen. But manufacturers and buyers still pick this kind of expensive material due to its good quality and high compressive strength. By means of researching, reading, and consultation, the researchers found out that using plastic wastes and chicken eggshells is a big help for increasing the compressive strength of something. The researchers also thought that it can likewise help in increasing the compressive strength of concrete hollow blocks. The compressive strength of hollow blocks was tested to know if it can really help in making the hollow blocks stronger and sturdier.

METHODS

Chicken eggshells were collected from the school canteen. These were cleaned, dried, pulverized, and set aside. Plastic wastes were also collected from the surroundings. These were cut into small pieces and set aside. The controlled setup was prepared by mixing 2000 grams of sand, 500 grams cement, and 25 milliliters of water. Treatment 1 was prepared by mixing 2000 grams of sand, 500 grams cement, 50 grams of eggs shells, and 25 milliliters of water. Treatment 2 was prepared by mixing 2000 grams of sand, 500 grams cement, 50 grams of plastic wastes, and 25 milliliters of water. Treatment 3 was prepared by mixing2000 grams of sand, 500 grams cement, 50 grams of eggs shells and Plastic Waste, and 25 milliliters of water. Three samples of concrete hollow blocks per treatment were tested for compressive strength.

RESULTS

Results reveal that the sample hollow blocksfrom the controlled setup obtained a mean compressive strength of 167 psi. Sample hollow blocks from Treatment 1 obtained a mean compressive strength of 102 psi. Sample hollow blocks from Treatment 2 had a mean compressive strength of 104 psi. Sample hollow blocks from Treatment 3 got a mean compressive strength of 92 psi.

DISCUSSIONS

Results reveal that the controlled setup had a higher compressive strength compared to any of the treatments with eggshells and plastic wastes as aggregates.
