EXPERIMENTAL INVESTIGATION ON PARTIAL REPLACEMENT OF CEMENT BY SUGARCANE ASH AND QUARRY DUST AS FINE AGGREGATE.

This paper presents an experimental investigation on the properties of concrete in which like cement is partially replacing by used nano silica and is partially replacing by used waste foundry sand. Because now a day the world wide consumption of sand as cement and as fine aggregate in concrete production is very high. Nano silica and waste foundry sand are major by product of casting industry and create land pollution. The cement will be replaced with nano silica and the river sand will be replaced with waste foundry sand (0%, 5%, 10%, 15%, 20%). This experimental investigation was done and found out that with the increase in the nano silica and waste foundry sand ratio. Compression test has been done to find out the compressive strength of concrete at the age of 7, 14, 21, and 28. Test result indicates in increasing compressive strength of plain concrete by inclusion of nano silica as a partial replacement of cement and waste foundry sand as a partial replacement of fine aggregate.

Quarry Dust

Large quantity of the quarry dust gets produced annually in the quarries during the extraction of the crushed coarse aggregate. As a result, disposal problems of this material gain significant momentum as these disturb environmental systems also. Now-a-days many of the countries like India is facing problems of ban on the extraction of sand and lacunae in procuring of fine aggregate, which is important constituent of the concrete. To overcome this problem, present study is focused on the suitability to utilize the quarry dust in Self Compacting Concrete (SCC) partially as fine aggregate with the natural fine aggregates. In this work, quarry dust is used as replacement of sand in a different level (0%, 15%, 30%, 45% and 60%) for producing the SCC. Fresh properties such as slump flow and V-funnel time have been measured for all mixes and hardened properties as compressive strength, splitting tensile strength and flexural strength of the concrete have been checked for all the mixes and it has been found that optimum utilization of quarry dust up to 30% can been done to produce SCC without compromising with its properties.

Quarry Dust

Demand for natural sand in concrete is increasing day by day since the available sand cannot meet the rising demand of construction sector. This paper reports the experimental study undertaken to investigate the influence of partial replacement of cement with Ground Granulated Blast Furnace Slag(GGBFS) in concrete containing quarry dust as fine aggregate. The cement was replaced by 10%, 20%, 30%, 40% and 50% of GGBFS and tests were conducted to determine the optimum level of replacement of GGBFS in quarry dust concrete. The specimens were subjected to compressive strength, split tensile strength, flexural strength, and bond strength tests at 7days, 28days, 56days, 90days and 150 days. The resistance to corrosion is evaluated based on the performance of the concrete for the penetration of chloride ions by means of impressed voltage technique in saline medium and Gravimetric weight loss method. Results herein reveal that an increase in slag proportion increases the strength properties and decreases the rate and amount of corrosion of reinforcement and among the various percentages of replacement 40% is found to be optimum with better strength and corrosion resistance properties.
