3.2. Mechanical Properties 3.2.1. Compressive Strength. The compressive strength of all mixtures was obtained at ages of 7, 28, 90, and 180 days, and the values are summarized in Table 4 and presented in Figure 4.The main objective of this research is to utilize FS as a substitute material in concrete production and not to enhance the strength properties of the concrete.
strength decreases. • Use of fly ash in concrete can save the coal & thermal industry disposal costs and produce a 'greener' concrete for construction. • The cost analysis indicates that percent cement reduction decreases cost of concrete, but at the same time strength also decreases.
compressive, split tensile and flexure strength of concrete. River sand is the most commonly used fine aggregate in making concrete. But extensive use and high transportation cost of sand gives rise to expense, so to cut down the cost of sand, granite powder is used as a replacement of sand with variable proportion of 10%, 20% & 30%.
High-strength concrete: Pre-mixed of cement, sand, gravel and additives, this concrete blend is perfect to use as a foundation, footer or bases for heavy equipment. It typically sets in about 10-12 hours. Crack-resistant cement: A pre-blended mix of cement, sand, gravel and additives, this mix is the most durable, meant to reduce cracking and ...
Used foundry sand (UFS) (Fig. 4.1) is a discarded material coming from ferrous (iron and steel) and nonferrous (copper, aluminium, and brass) metal-casting industry to create molds and cores. About 1 ton of foundry sand for each ton of iron or steel casting produced is used (Siddique and Noumowec, 2008). Typically, suppliers of the automotive ...

In this study, the potential re-use of waste foundry sand in high-strength concrete production was investigated. The natural fine sand is replaced with waste foundry sand (0%, 5%, 10%, and 15%).
recycled concrete dust, and others are being researched from past two decades, in view of conserving the ecological balance. In this direction, an experimental investigation of strength and durability was undertaken to use "Spent Fire Bricks" (SFB) (i.e. waste material from foundry bed and walls; and lining of chimney which is adopted in many
Dec 09, 2019· The purpose of this paper is to examine the mechanical properties, material composition of spent garnet as a sand replacement in high-strength concrete at room and elevated temperatures. Bonding of the concrete containing spent garnet and reinforcing rebar is investigated. Moreover, the optimum thickness of concrete cover subjected to elevated temperatures is investigated.,First, the .
This paper is a literature review about the use of wastes in masonry mortar. Wastes such as wood waste ash, municipal solid waste, ground waste seashells, glass waste, fly ash, corn cob ash and palm oil fuel ash are used to replace cement as the binding material. Wastes of Cathode Ray Tube (CRTs) glass, plastic waste, construction demolition wastes, foundry sand and quarry dust are used as a ...
This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete. An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented. The proportions of replacement were 0%, 50%, and 100% by mass of aggregates.
And rebutted tyre waste came into the picture to reduce the solid waste and to reduce the scarcity of natural aggregates for making concrete. The ceramic tile waste is not only occurring from the ...
Sep 01, 2011· The concrete with 10% waste foundry replacement may indicate the optimum reallocation amount of waste foundry sand. The concrete with 10% waste foundry sand shows almost the same strength of control concrete mixture; whereas the other entire waste foundry added mixtures exhibit lower values than that of the control.
May 23, 2017· The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduc...
As shown in the Beneficial Reuse of Foundry Sand from the Metal Casting Sector figure, foundry sand can be used almost anywhere sand is used. Construction contractors use it for structural fill, backfill, and pipe bedding. The cement sector uses it as an ingredient in cement. It can be used to make asphalt, bricks, concrete blocks, and ...
Dec 15, 2017· Waste foundry sand is one such alternative to regular sand, constituent of concrete. However, waste foundry sand is a lower quality material and has some adverse effects on concrete properties when used in high or complete replacement to sand, the majority of research studies showed that, yet it can be used to make structural concrete as well.
Donmez S (2010), "Re-usage of waste. foundry sand in high strength concrete", Waste Manage, Vol. 30, ... But use of waste foundry sand (WFS) for land filling is becoming a problem due to rapid ...
Jun 15, 2020· the SPBs were found to have 2.5 times the strength of normal red clay bricks while, to be consumed they need around 70 to 80% of the foundry dust with 80% lesser use .
replacement of 10% natural sand with waste foundry sand to be the most suitable for asphalt concrete mixtures. Further, they establish that waste foundry sand does not significantly affect the environment around area where the asphalt concrete is laid, hence safe for re use. Thirdly, Lin, C. Cheng, A. Cheng and Chao [6]conclude that
Jun 12, 2019· The reduced glass is then substituted for sand in polymer concrete to create a high strength, water-resistant material "suited to industrial flooring and infrastructure drainage, particularly in areas subject to heavy traffic such as service stations, forklift operating areas and airports".
Use of waste foundry sand in concrete and concrete related products like bricks, blocks and paving stones has been reported by Khatib and Ellis (2001), Naik et al. (2003, 2004), Siddique et al. (2009), Etxeberria et al.(2010) and Guney et al.(2010) . Khatib and Ellis (2001) investigated compressive strength of concrete containing foundry sand as
