STUDY ON MECHANICAL PROPERTIES OF M30 GRADE CONCRETE BY PARTIAL REPLACEMENT OF CEMENT WITH POZZOLANICMATER0020IALS

Abstract

The use of pozzolanic materials as partial replacements for cement in concrete has become a key area of research due to concerns regarding environmental impact and material efficiency. This study investigates the effects of such replacement on the mechanical properties of M30 [1:2.5:3.5] grade concrete. Which is a common grade concrete used in construction. The main objective is to assess how incorporating different pozzolanic materials [eg: silica fume, rice husk ash and fly ash] affects key mechanical properties like compressive strength, split tensile strength, flexural strength, workability and durability. Researchers have explored various pozzolanic materials and replacement levels. [some studies found that replacing cement with up to 15% silica fume and fly ash] can lead to an increase in compressive strength. Using 25% of fly ash ,15% of rice husk and 5% silica fume. Conducting some tests on mix design like fresh concrete test and hardened concrete test. Low-cost construction materials like fly ash and rice husk ash, play a crucial role in addressing affordability and sustainability challenges in the construction industry. This abstract explores various types of low-cost materials that have gained prominence due to their economic and environmental benefits. Materials such as stabilized earth blocks, bamboo, recycled materials, and alternative industrial by-products are examined for their suitability in construction. This study explores the use of low-cost construction materials in the development of affordable housing, aiming to address the graving need for building that meet cost-effective and sustainable Solutions. They are not only evaluating theoretical economical but also essential structural, thermal, and aesthetic requirements.
