The proposed study present behaviour of concrete with inclusion of waste foundry sand (WFS), waste glass, and glass fiber in different concrete trial mixes. Waste foundry sand (WFS) is basically by-product formed from metal casting industries ferrous or non-ferrous, which due to rapid concrete construction in world used as an alternative of sand. Waste glass can be used in concrete in crushed form as a replacement of aggregate or in powdered form as a replacement of cement, the only problem with waste glass is it is prone to alkali-silica reaction due to different composition of different types of glasses. Glass fiber is added with waste glass and waste foundry sand (WFS) to increase strength. Normal concrete grade M25 (1:1:2) is used for this experimental purpose, different concrete trials were casted which consist of replacement of sand with waste foundry sand in different proportion (0%, 10%, 20%, and 30%). Next trial consists of optimum value of (WFS) with different proportion of waste glass (0%, 10%, and 20%, 30%) as a replacement of fine aggregate. Final trial consists of addition of glass fiber (0%, 0.25%, 0.50%, and 0.75%) in optimum value of second trial. Mechanical properties of concrete compressive strength, split-tensile strength, flexural strength was examined at 7, 14, 28, and 56 days curing period.

Flowable fill is generally a mixture of sand, fly ash, a small amount of cement, and water. Sand is the major component of most flowable fill mixes; consequently, using a waste material as a substitute for natural sand results in the beneficial use of the waste material. Waste foundry sand (WFS) was used as a fine aggregate in this study. Three green sands from ferrous foundries and two Class F fly ashes were used. A natural river sand was used for comparison. The flow behavior, hardening characteristics, and ultimate strength behavior of flowable fill were investigated. The penetration resistance necessary to sustain walkability as the fresh flowable fill hardens was determined, and the time necessary to achieve this penetration resistance was defined as “walkable time.” The unconfined compressive strength at 28 days appeared to correlate well with the water-to-cement ratio. The 90-day compressive strength test results indicate that a maximum rise of 25 to 30 percent in long-term strength with respect to 28-day strength can be expected. The permeability of hardened flowable fill was found to be low (around 10−6cm/sec). The pH of pore solution of hardened flowable fill indicated that the potential for corrosivity is low. The toxicity tests indicated that some WFSs are environmentally safe. The concepts explained are not necessarily restricted to flowable fill containing WFS; they can be generalized as being applicable to all flowable fills.

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.

Waste Foundry Sand

Waste foundry sand (WFS) is a ferrous and non-ferrous foundry industry by-product, produced in the amount of approximately 700 thousand tons annually in Poland and it is estimated that only a small percentage of this waste is recycled. The study used WFS to produce ultra-high performance concrete (UHPC) as a partial substitute for quartz sand. It was replaced with WFS levels of 0%, 5%, 10%, and 15% by weight of quartz sand content. The UHPC mixtures were produced and tested to determine the compressive strength, flexural strength, splitting tensile strength as well as the modulus of elasticity at 28, 56, and 112 days. Scanning electron microscope (SEM) analysis was done to identify the presence of various compounds and micro-cracks in UHPC with WFS. The results revealed an increase as well as an insignificant decrease in the mechanical properties up to 5% and 10% WFS replacement, respectively. These studies also prove improvement in the microstructure of UHPC up to a 5% WFS level. In all the tested properties in this work, 5% WFS was found to be an apt substitute for quartz sand.

Abstract: Used or Waste Foundry Sand can be utilized as an alternative for fine aggregate in conventional concrete. WFS or UFS can be used in large volume by partially replacing sand in construction industries. Here the strength properties of M25 and M60 grade concrete replaced by WFS by 0,10,20,30,40 and 50 percent w/w of fine aggregate is evaluated by measuring compression, split tensile and flexural strength at 7 days and 14 days.

Natural Aggregates

The demand for natural aggregates (river sand) is increasing day by day, leading to the destruction of the environment, a burden that will be passed on to young people. Further, wastes from various industries are being dumped in landfills, which poses serious environmental problems. In order to ensure sustainability, both the issues mentioned above can be solved by utilizing industrial waste as aggregate replacement in the concrete construction industry. This research is done to find out the results using two substances viz., waste foundry sand (WFS) and coconut shell (CS) substitute for river sand and coarse aggregate. Many researchers have found the maximum benefits of substituted substances used in cement, which has material consistency. This current observation explores these strong waste properties of waste-infused concrete and cement, which experience shrinkage from drying out. The replacement levels for waste foundry sand were varied, between 10%, 20%, and 30%, and for CS, it was 10% and 20%. The experimental outcomes are evident for the strength, which increases by using WFS, whereas the strength decreases by increasing the CS level. The concrete that experiences shrinkage from drying out is included in the waste material, showing a higher magnitude of drying shrinkage than conventional concrete.
