Self Compact Concrete

This document demonstrates the possibility of using foundry sand waste as a partial replacement of sand in self-compact concrete. Self-compacting concrete, as the name implies, is a type of concrete that does not require an external or internal seal because it is aligned and consolidated under its weight. Foundry sand is a high-quality silica sand that is used as a molding material for the ferrous and non-ferrous metal casting industry. It can be reused in foundries, but after a certain period it cannot be used further and becomes waste, called waste, used or used foundry sand (WFS, UFS or SFS). This experimental study was conducted to assess the strength and strength of SCC properties in which natural sand was partially replaced by foundry sand waste (WFS). Natural sand was replaced by four percent (0%, 10%, 15%, 20%, 30% and 40%) WFS by weight.

Foundry Sand

Concrete is the most important civil engineering material in construction buildings and industries because increase the strength properties. Rubber and foundry sand are produced excessively worldwide every year. In such a case the reuse of rubber and foundry sand would be a better choice. In order to reuse rubber wastes, rubber tyre chips was added to concrete as coarse aggregate and In order to reuse foundry sand, foundry sand was added to concrete as fine aggregate and its different properties like compressive strength. As a result it was found that rubberized and foundry sand concrete is durable, less ductile, has greater crack resistance but has a low compressive strength when compared with ordinary concrete. Due to rapid growth in automobile industry use of tyre increase day to day and there is no reuse of the same to decrease the environmental pollution .in this paper we will study about physical and mechanical properties of concrete containing recycled tyre or rubber material aggregate. This study present the information about the civil engineering application of foundry sand, which is technically sound and is environmental safe. Foundry sand can be used as a partial replacement of fine aggregate and rubber tyre chip partial replacement coarse aggregate .foundry sand can be used in concrete to improve its strength and other durability factor. Foundry sand is high silica sand that is a by – product from the production of both ferrous and non-ferrous metal casting. The fresh & hardened properties of concrete such as workability, compressive strength, are the identified.

The paper aim is to acknowledge the use of Quartz Sand (silica sand) & Metakaolin in replacement of natural sand and cement. As the natural sand is depleting at an alarming rate due to perpetual mining and on other side the emission of co2 from production of cement causing global warming. The M30 grade is prepared as well as evaluated for strength characteristics viz. split tensile, compressive and flexural. Ordinary Portland cement is replaced with metakaolin at 0,10,20,30,40 and 50%, while the fine aggregate is replaced with Quartz sand at 40% constant by weight. The specimens are casted and tested for split tensile, compressive and flexural strengths after curing for 7,14,28 days.

Self-compacting concrete which commonly abbrevited as SCC is a special concrete that have the ability to consilodate fully under its own self-weight without any internal or external vibration. This paper presents the experimental investigation carried out to study the strength of self-compacting concrete incorporating bottom ash at different replacement level of natural sand. The composite cement was used and the replacement level of bottom ash to natural sand is set up to 30% by volume. The strength properties such as compressive strength, split tensile strength and flexural strength of the concrete at the age of 7 and 28 days of curing day were conducted. Results shows that the strength of the concrete with bottom ash increased up to replacement level 15% higher than control specimens. This show that bottom ash can be used as supplimentary cementitious materials, having the pozzolanic reactivty.

Casting Industry

Waste foundry sand is the by-product of metal casting industry. Rice hull which is often burned after it is removed from rice is also a by-product of the agriculture industry. Disposing of these wastes leads to the environmental pollution. To optimal use of these wastes and avoid the adverse effects of dumping them, regular sand has been partially replaced with the waste foundry sand and rice hull ash pozzolan has been also used as a partial replacement for cement in making concrete. XRF, XRD and SEM experiments, compressive strength, tensile strength (Brazilian), flexural strength, modulus of elasticity and water absorption tests have been conducted. The results showed a slight decrease in compressive strength of samples in which regular sand was replaced with waste foundry sand by 15 percent; however, adding the rice hull ash to this mixture led to make a concrete comparable with control one. Also, using foundry sand in mix designs affects their physical performance. Moreover, the use of waste foundry sand in concrete is both economically and environmentally suitable.

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.

This paper presents research results of recycled fine aggregate concrete testing. The main aim of this contribution is verification of properties of fine aggregate concrete with partial replacement of fine natural aggregate by recycled masonry aggregate originated from construction and demolition waste. The influence of partial replacement of natural sand to mechanical properties and freeze-thaw resistance is described. The compressive strength and flexural strength were tested at the age of 28 and 60 days and after 25, 50, 75 and 100 freeze-thaw cycles. Partial replacement of natural sand was 0, 25 and 50 % for all these tests. Prismatic specimens were examined.

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.
