To evaluate the high strength concrete compressive strength, split tensile strength, and flexural strength have been studied in this investigations. Materials: High performance concrete was made of cement, sand, fly ash, GGBS, foundry sand, aggregate, water and chemical admixture.
Foundry sand is high quality silica sand with uniform physical characteristics. Foundries attempt to reuse as much of sand as possible within the foundry process itself, but eventually a fraction becomes spent and ... It is evident from Fig. 10 that cube compressive strength of concrete .
Review Utilization of Waste Foundry Sand and Granite . strength may increase with replacement of WFS up to 20-30% and for G S up to 15-20% Keywords— Concrete Waste Foundry Sand Granite Slurry Compressive Strength Eco-Friendly I INTRODUCTION Concrete is the backbone of all the construction and development activities around the world being the most extensively used .
Developing Sustainable Ultra High Strength Concrete Mixtures Using Spent Foundry Sand 345 classification achieved through chemical analyses and particle size. The research conducted by Prabhu, G. G. et al. (from a cast iron plant) showed that the main source of foundry waste is molding sand (360 t/d). The remaining are from molds from dust
foundry sand and used foundry sand. Concrete performance was evaluated with respect to compressive strength, tensile strength, and modulus of elasticity. At 28-day age, concrete containing used foundry sand showed about 20-30% lower values than concrete without used foundry sand. But concrete containing25% and 35% clean/new foundry sand gave ...
Comparative strength development of foundry sand mixes in relation to the control mix (i.e., mix without foundry sand) was observed. Singh and Siddique [ 30 ] performed an experimental investigation to evaluate the strength and durability properties of concrete mixtures, in which natural sand was partially replaced with the WFS.

In this study, effect of foundry sand as fine aggregate replacement on the compressive strength, flexural strength and split tensile strength of concrete with a mix proportion of 1: 1.28: 2.56: 0.45 was investigated at different limited curing periods (7 days and 28 days).

4.5. Foundry Sand Most of the metal industries prefer sand casting system. In this system mould made of uniform sized, clean, high silica sand is used. After casting process foundries recycle and reuse the sand several times but after some time it is discarded from the foundries known as waste foundry sand.
Abstract Metal foundries use a large amount of sand as part of the metal casting process. Foundry industries generally recycle and reuse the used foundry sand .

Metal foundries use a large amount of sand as part of the metal casting process. Foundry industries generally recycle and reuse the used foundry sand many times in casting process. When the sand can no longer be reused in the foundry, it is removed
What is Foundry Sand? • Foundry sand is a high-quality uniform silica sand that is used to make molds and cores for ferrous and nonferrous metal castings. • Foundry sands typically comprise of >80% high-quality silica sand, 5-10% bentoniteclay, 2 to 5% water and less than 5% sea coal.
Aug 01, 2010· The high replacement of the blended foundry sand caused a reduction in strength as compared with concrete incorporating white sand or waste foundry sand. Naik et al. (2004) studied the influence of waste foundry sand as well as fly ash and bottom ash on the compressive strength of bricks, blocks, and paving stones.
When normal ready-mix concrete is made the largest aggregates in the mix can range from 1-1/2 inches down to 3/8ths of an inch in size with compressive strengths that can be as high as 10,000 psi.
used foundry sand. For M 75 grade concrete with fly ash as mineral admixture, the 7th day compressive strength increases with the percentage replacement of fine aggregate with used foundry sand. For high performance concrete with ground granulated blast slag, 7th day compressive strength increases up to 10% replacement and further decreases.
High-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.

AS&G's High-Strength Concrete Mix is used for setting fence posts, anchors and sleeves. Mix can also be used for concrete patching and slabs greater than 2" or thicker, and for other applications where AS&G's High-Strength Concrete Mix is desired. Concrete setting time: 5 - 6 hours. High-Strength Concrete Mix - Product Info High-Strength Concrete Mix [SDS] Product Number Size Estimated ...
2) Substitution of 30% of foundry sand results decrease in compressive strength for M20 & M30 grade of concrete when compared to mixes with natural sand 3) Substitution of 20% (A2) foundry sand in M20 grade concrete & 10% (A1) foundry sand in M30 grade concrete gives better results. 3 h 3.5 Percentages of F.S
This research work was on the evaluation of the flexural strength and compressive strength relationship of spent foundry sand (SFS) concrete. The relationship was established using a concrete mixture of 1:1.71:2.56, a cement content of 404 kg/m2, and a water-cement ratio (w/c) of 0.52.
