Thus, the use of recycled aggregate concrete is need of the hour for the sustainable development of society with savings in natural resources and materials which are depleting at quite an alarming rate. Foundry sand is high quality silica sand which is a byproduct of ferrous and nonferrous metal casting .
aggregate with waste foundry sand. The results showed that replacement of 10% aggregates with waste foundry sand was found to be the most suitable for asphalt concrete mixtures as higher replacement levels caused reduction in strength beyond tolerances. Naik et al. [2003] conducted the tests for abrasion of concrete with foundry sand.
The main purpose of this research study is to compare the strength properties (Mechanical) of High Strength Concrete (HSC) using Foundry Slag (FD) and Alccofine (AF) for different curing ages (7, 14, 28, 56 and 90 days). This paper discussed the use of Foundry Slag (FD) as
Experimental study on waste foundry sand and steel slag concrete Chandrashekhar D. Sahare ... Metal industries use sand casting in which moulds are made of uniform sized, clean, high silica sand. After the casting, process ... Tensile strength of a waste Foundry Sand and Steel Slag Concrete (M 25 grade) after 7 days of curing S.

Sep 01, 2015· foundry sand are annually used in various foundry sectors. In this study, a series of testing programs was conducted on the fresh and hardened concrete to investigate the reuse of waste foundry sand in highstrength concrete. The control concrete mixture was arranged so as to achieve a highstrength concrete of about 65 MPa.
The pure aggregate gave a 28 days concrete strength of N/mm2, while 25% foundry gave N/mm2, other samples gave results that were very poor due to the presence of large clay particles. Foundry sand can be applied to fine aggregate in concrete up to 25% inclusion. Keywords: Foundry sand, Clay particles, Concrete, Pollutant. INTRODUCTION
strength of concrete by partial replacement of artificial sand by foundry sand as fine aggregate. Tests were carried out on cubes, cylinders and unreinforced beams to study the mechanical properties of concrete using foundry sand and compared with concrete with artificial sand as fine aggregate.
Fig. Strength of Concrete with various levels of replacement of Foundry Sand after 28 56 days. Tensile Strength It was found that split Tensile strength of Concrete incorporating Foundry Sand (using 10%, 205 and 30% replacement levels with fine aggregate and a w/c of ) depended on the percentage of Foundry Sand used.
Mix design of high strength concrete is influenced by properties of cement, sand aggregates watercement ratio have compressive strength above 40 MPa. To achieve high strength, it is necessary to use lowest possible watercement ratio, which invariably affects the workability of the mix and necessitates the use of special vibration techniques ...
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 containing 25% and 35% clean/new foundry sand gave almost the same compressive ...
User Guidelines for Waste and Byproduct Materials in Pavement Construction [ Asphalt Concrete] ... ORIGIN. Foundry sand consists primarily of clean, uniformly sized, highquality silica sand or lake sand that is bonded to form molds for ferrous (iron and steel) .

A mix design procedure for highperformance concrete mixes has been presented in this paper. Since rheological parameters and compressive strength are fundamental properties of concrete in two different stages of production, the correlation between rheological parameters and compressive strength .
The percentage replacement of foundry sand with sand includes 10percent, 15percent, 20percent, 25percent, 30percent. The binder is 70percent of cement and 30percent of tile powder. The mix design for self compacting concrete and the tests to be conducted like material strength tests and durability tests are being discussed in this testing, paper.

The substitution of foundry sand in concrete reduces the voids in concrete and has helped to spread the C–S–H gel widely in the concrete ... higher and this difference in strength is not relatively high ...
Sand topping concrete mixes are used for concrete overlays less than 2 inches thick and for leveling and patching floors, steps and walkways. High strength concrete supports heavy loads with less concrete and is most commonly used to build highrise buildings.
foundry sand (WFS) and reclaimed WFS in high strength concrete production. The natural fine sand replaced with waste foundry sand(5%, 15%, 25%, 35%, 50%).The findings from a series of test program has shown in compressive strength, tensile strength water absorption and porosity of concrete containing waste foundry sand. Keywords—
The pH value of foundry sand is found to be 4 and it depends on the binder used for type of metal cast. The foundry sand cannot be used for Reinforced cement concrete works since it can corrode ...
