2017-6-3 13.42% by the replacement of 20% of foundry sand over normal sand. Their results have concluded that up to the 60% of the replacement of the foundry sand gives rise to the compressive strength of the concrete. The split tensile strength increases up to 60% replacement of foundry sand after that decrease till 100%.

2020-8-1 Foundry sands are classified based on the type of binders used, i.e. clay or chemically bonded sand (Siddique and Singh, 2011). Foundry sands are usually recycled and reused till its properties get degenerated to a level where it is not possible to use it further after which it is discarded from the foundry ( Behnood and Golafshani, 2020 ).

2012-1-1 Highlights This paper is utilization of waste foundry sand (WFS) as partial replacement of fine aggregate. Fine Aggregates (Sand) has been replaced with 0%, 5%, 10%, 15%, and 20% WFS. Strength properties such as compressive strength, splitting tensile strength, and modulus of elasticity were investigated. Ultrasonic Pulse Velocity and permeability (chloride) were also studied. In this ...

2014-12-1 Because the waste foundry sand has a larger particle size than clay, pores of different sizes were distributed throughout the tile body in specimens with waste foundry sand supplementation. This increase in porosity led to greater water absorption, which became readily apparent at foundry sand replacement rates greater than 40%. 4

2018-12-31 In this experimental study, an effort has been made to study the feasibility of using foundry sand as partial replacement for natural fine aggregate to produce concrete with desired properties. Physical and mechanical properties of the produced concrete were studied by incorporating foundry sand, 10, 20, 30, and 40% of the mass of total fine ...

2018-12-19 Foundry sand (FS) waste creates a serious solid waste management problem worldwide due to the high volumes produced, necessitating alternatives to landfilling. A possible route is its use in concrete; however, the current consensus is that FS can only be used for modest sand replacements, based mostly on evidence on concrete with clay-bound FS (greensand). Conversely, this study

2021-10-9 From the mechanical properties of concrete containing both the waste products, the optimum replacement levels were arrived at 25 % and 15% for waste foundry sand and coconut shell. The durability properties such as water absorption, porosity, sorptivity and water permeability are found for improvised concrete and compared with normal concrete.
