Abstract - The main objective of this study is to utilize
weight of the brick is 3.5 kg. Brick dimensions were 230 mm x 110 mm x 90 mm which were adopted. The foundry soil was separated by the percentage of 5%, 10%, 15%, 20%, 25%, and 30% of the total mass weight of the standard weight of the brick. The samples were cast in the brick chamber with a mixed ratio of catlinite material by hand mix method. Then dried up to 2–3 days & burnt in the kiln for a day and night. 25% FS specimen had the suitable compressive strength value of 4.86 MPa.
waste foundry sand and a SCM (supplementary cementitious material) in sustainable brick production. One of the oldest building materials used in India is fired clay bricks. India is the second largest producer of bricks in the world, with about 240 billion bricks produced every year. The constant growth in economy and population, along with urbanization has resulted in increasing demand for buildings and infrastructure in our country. So, there will be high demand for primary building materials such as bricks. One of the major problems in clay brick production is the use of agricultural clay, which is of great significance to farmers. Disposal of industrial wastes which are hazardous to environment is also a major problem around the world. So, in this study, the behavior of bricks incorporating industrial wastes such as foundry sand & silica fume will be evaluated. Here in this study up to 50% replacement of clay in traditional fired clay bricks to industrial waste was investigated. It was found that bricks with 25% foundry sand and 15% silica fume by weight of clay had the best results. Also, the masonry application of proposed brick was evaluated and its behavior studied.
Nabil Hossiney et al (2018) [2] studied the use of foundry sand from the Belgian foundry industry in the manufacture of bricks. Mixes selected were 0%, 30%, 40% & 50% WFS. About 400 bricks were produced for each mix. Results indicated no change in appearance, Minimum compression resistance of 3.3 MPa & Maximum water absorption 21.61% for 50% Foundry sand. There was insignificant difference in apparent porosity, water-absorption & specific gravity, compared to commercial bricks. M. Serhat Baspinar et.al. (2010) [3] studied the potential of using silica fume in fired clay brick production. 0%, 2.5%, 5% and 10% silica fume by weight of clay was added to original brick clay and fired at temperatures between 800 and 1100°C. authors concluded that although a decrease in the bulk density of the bricks was observed with silica fume addition, an increase in the strength values was observed for silica fume addition above 2.5%. A noticeable increase in the strength was also observed at higher firing temperatures.

1.INTRODUCTION The Indian economy is now growing at a fast pace. India has now become the fifth largest economy in the world. There is a constant growth in both economy and population hand by hand along with rapid urbanization. The overall urban population of the country has increased, there will a major need for infrastructure and housing. This will in turn increase the demand for construction materials such as bricks. As demand for fired clay bricks rises, along with it increases the demand for agricultural clay, leading to land degradation, which is a major problem in our country. So, in this study, industrial waste materials are added to bricks by replacing various amounts of clay for sustainable brick production.
3. EXPERIMENTAL INVESTIGATION 3.1 Materials Used 3.1.1 Foundry sand Waste foundry sand (WFS) is a by-product of metal casting industries, used to create molds & cores. Most of the world’s WFS is mainly generated by suppliers of automotive industries. Millions of tons of foundry sand go to the landfill annually. The waste foundry sand for this study was collected from the metal casting unit of Autokast Ltd, Kerala. Obtained foundry sand was tested for specific gravity and fineness modulus and was found to be 2.28 and fineness modulus 1.9 respectively.
2. LITERATURE SURVEY Various studies are done by researchers on using industrial wastes in brick production. Some of them include: S. Rubini et al (2019) [1] studied the performance of bricks with fractional restoration of foundry sand. The standard
