Comparative Study on Conventional Concrete and RHA Mixed Concrete

Concrete is one of the most used materials in the field of construction. These days due to population growth, the need for infrastructure is growing day by day. This increases cement production. In the current situation total cement production is 4.1 billion tons worldwide. This large amount of production encourages natural use resources and is not very safe in the environment. Large quantities of waste products delivered to the manufacturing industry, for example, mineral slag, fly ash, silica fumes, rice husk ash and more. rice husk ash is an available agricultural product from rice mills, the husk found in the mill is useless which means it is not even used to eat animals. That’s why it is used as fuel in various industries the burning temperature is very high which is why they are found in that RHA is very simple. The work here is about the gradual conversion of RHA cement to concrete by various percentages such as 0%, 5%, 7.5%, 15% weight of cement. Various investigations were conducted to determine the workability, compressive strength, flexural strength at 7-day and 28-day cured concrete samples. Results obtained from experiments with satisfactory modification cement with ash husk ash is featured in this research paper.
