Abstract - Now a day the worldwide consumption of sand
explore the possibility of waste foundry sand as a sand replacement in concrete.
as fine aggregate in concrete production is very high. Several developing countries have encountered some strain in the supply of natural sand in order to meet the increasing need of the infrastructural development in recent year, to overcome the stress and demand of river sand, researchers and practitioners in the construction industry have identified some alternative. One of them is foundry sand, it is a high quality silica sand with uniform physical characteristics and by product of ferrous and non-ferrous metal casting industry. It is proved that foundry sand used as fine aggregate will enhance the strength of concrete to a greater extend. This paper presents an experimental investigation on the properties of concrete in which fine aggregate is partially replacing by used foundry sand. The only variable considered in this study is volumetric replacement (10%, 20%, 30%, 40%, and 50%) of sand. Out of these 5 replacement levels best 3 were choose by trial works. The concrete was tested for slump test, compression test, flexural test, split tensile test for 7 & 28 days and acid attack test for 7 days.
The main objective of this experimental work is to compare the effect of foundry sand in concrete with the conventional concrete and to see the effect of foundry sand inclusion in concrete. Also the study is summarize based on compressive strength, split tensile strength, flexural strength and acid attack test of concrete with the replacement of fine aggregate by foundry sand.
2. LITERATURE REVIEW Several studies have been carried out for analysis the properties of foundry sand and also the strength of concrete by in cooperating foundry sand in partial as a fine aggregate. Some of them were discussed below. By Amitkumar D Raval et al., [1] They carried out an experimental investigation on the topic ‘effect of foundry sand as fine aggregate replacement in concrete’ with an M25 grade at different limited curing periods (7 days, 14 days and 28 days). Fine aggregate was replaced with 10%, 20%, 30%, 40% and 50% of WFS by weight. The test result showed that the compressive strength increased with an increase in the amount of foundry sand, up to 30% replacement in concrete, beyond that it decreases.
Key Words: foundry sand, ordinary Portland cement, compressive strength, split tensile strength, flexural strength, acid attack test.
1. INTRODUCTION
By Dushyant Rameshbhai Bhimani et al., [3]
Concrete is a major construction material that is used world-wide, because of its considerable durability than other construction materials. But now a day there is a scarcity in fine aggregates. So we have to look for different materials to reduce the quantity of basic natural materials in the concrete mix without changing any mix design procedure and consideration. The use of cheaper materials without loss of performance is very crucial to growth of developing countries. We cannot replace the whole basic materials in the concrete, but we can replace with other materials to some extent. So this study was undertaken to
They carried out an experimental investigation on the topic ‘Strength Behavior of Foundry Sand on Modified High Strength Concrete’. Fine aggregate was replaced with 0, 15, 25 & 35% of WFS by weight in concrete. Compressive strength, split tensile strength and flexural strength tests were carried out to evaluate the strength properties of concrete. Based on their result values they stated that, 25% replacement give higher strength. They also stated that using of foundry sand for construction work will be more effective and efficient than land filling.
