Experimental Study to Enhence the Compressive Strenth of Concrete Using Cow Dung Ash, Rice Husk Ash and Alccofine

Abstract

Cement, which makes up the majority of concrete, emits a significant amount of carbon dioxide, concrete has a remarkable environmental impact. If the amount of cement used in manufacturing of concrete is minimized by the use of mineral admixtures without compromising durability criteria, it is possible to lessen the environmental impact of concrete. In order to boost the strength and durability of concrete, which is formed of aggregates, portland cement, and water, at least one additional element, such as admixtures, supplemental cementitious material, or fiber, must be added. Pozzolanic elements like cow dung ash and rice husk ash can be incorporated into portland cement to create effective environmentally friendly concrete. The majority of the requirements for durable concrete can be met with the help of supplementary cementitious materials. Agriculture-based pozzolanic additives like Rice Husk Ash (RHA) and Cow Dung Ash (CDA) are widely available. Other supplemental materials like silica fume and fly ash are shown to be inferior to rice husk ash and cow dung ash. The goal of the current study is to examine the strength parameters of concrete of M20 grade adopting rice husk ash (RHA) and cow dung ash (CDA) as partial replacements for cement, respectively. In addition, concrete uses 5% of alccofine by volume. The specimens are prepared with partial replacements of cement by 0%, 5%, 10% and 15% of RHA and CDA. The sample specimens consist of concrete cubes, cylinders and beams. Compressive strength, split tensile strength and flexural strength tests are carried out and the test results are compared with that of conventional concrete.
