Slump flow, water absorption, concrete compression strength, and index void tests were performed to study the properties of fresh and hardened concrete made by substituting 10% and 20% of the sand by weight with foundry sand as concrete aggregate.
Foundry sand is a high quality silica sand used as a molding material by ferrous and non-ferrous metal casting industries. It can be reused several times in foundries but, after a certain period, cannot be used further and becomes waste material, referred to as used or spent foundry sand (UFS or SFS).
developed to predict concrete properties of blended aggregate concrete for use in the design tools, CRCP and JRCP, described in previous 422/1244 reports. A computer program, CHEM2, was developed, which allows the pavement designer to estimate the material properties of concrete from an inexpensive chemical test.
The foundry sand induces the beneficial effect of reducing drying shrinkage and water permeability as well as refinement of pore structures and better interfacial transition zone (ITZ). Results have indicated that foundry sand has potential for being used as fine aggregate in producing durable concrete.
foundry sands namely foundry sand with bentonite clay (FBC), Foundry Sand with Phenolic Resin (FPR) and Foundry sand with sodium silicate (FSS) were used. Figure 1 gives schematic of materials used for preparation of concrete samples in this research work and Table 1 gives properties of materials used in the experimental work.
The research was carried out by Naik et al. to develop concrete mixes incorporating used-foundry sand. Foundry sands (clean or used) were used to replace regular concrete sand to study properties of concrete density, compressive strength, modulus of elasticity, flexural strength and surface abrasion.
as plain epoxy polymer concrete, with the incorporation of 1% and 2% in mass of chopped glass and carbon fibers, respectively. The use of the specific percentage of reinforcement is followed based on the previous studies by the authors7,8. Foundry sand used in this study was a siliceous one, with very uniform grain and a mean diameter, d 50
paper also reports on the properties of special concrete with bottom ash as substitute for natural sand. Figure 2: Bottom ash applications as a percentage of totals reused. (ACAA, 2006) 2.0 MATERIAL AND EXPERIMENTAL WORK BA used was collected from the ash pond of TNB Electric power plant (Coal Power Station) in Perak.

higher than that of Portland cement mortar exposed to freeze-thaw cycles. The use of pumice aggregate as sand provides the resistance to sulfate attack. Keywords: Mortar, Pumice, Mechanical properties, High temperatures, Sulfate resistance Pumice is a natural material of volcanic origin produced by release of gases during the solidification
properties of foundry sand for use in Portland cement and concrete, hot mix asphalt, road subbase layers, embankments, and flowable fill. Recent studies addressing environmental concerns of using foundry sand, an industrial by-product, as a construction material are reviewed. Some case studies are presented to demonstrate
Printed sand molds are appropriate for smaller quantities or for geometry that is not supportable using a traditional sand casting. The surface finish and mechanical properties are consistent with traditional sand castings, while the tolerances are much closer to air-set sand casting tolerances.
In an American Foundrymen's Society study of asphalt concrete properties (using 10 percent foundry sand) compared with control mixes (without foundry sand), the results indicated little difference in Marshall design properties (e.g., voids, voids in mineral aggregate, stability, flow, and unit weight).
The properties of concrete containing foundry sand as a partial replacement of fine aggregate were investigated. Three types of sand used in foundries were considered, the white fine sand without the addition of clay and coal, the foundry sand before casting (blended), and the foundry sand after casting …
and moisture. The angularity of a sand increases with use because the sand is broken down by thermal and mechanical shock. • The porosity of the mold controls its permeability, which is the ability of the mold to allow gases generated during pouring to escape through the mold.
Conventionally concrete is mixture of cement, sand and aggregate. The properties of aggregate affect the durability and performance of concrete, so fine aggregate is an essential component of concrete. The most commonly used fine aggregate is natural river sand. The global consumption of natural sand is very high, due to the extensive use of ...

any other type of concrete, particularly in structures with large surface areas12. Recently, impregnation of nanoparticles into ordinary Portland cement (OPC) paste, mortar and concrete has received particular attention as a promising research field for nanocomposites, which can produce superior mechanical and physical properties in OPC composites.
Foundries successfully recycle and reuse the sand many times in the foundry. Classification of foundry sands depends upon the type of binder systems used in metal casting . Water . The water is used in concrete plays an important part in the mixing, laying compaction setting and hardening of concrete.
severe environments. High performance concrete incorporation silica and fly ash as pozzolanic mineral admixture is being increasingly used in the construction of structures for large projects. High performance concrete each commonly available in metropolitan areas. Because of superior mechanical properties and the
Moreover it is proved that aggregate's types has the severe effect on physic-mechanical properties of concrete as aggregate covered almost 70 to 80 percent of the total volume of concrete. This paper investigates the effects on properties of concrete due to types of crushed aggregates alone.
This paper presents the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate (regular sand) was partially replaced with used-foundry sand (UFS). Fine aggregate was replaced with three percentages (10%, 20%, and …
Foundry sand has the particle size distribution and mechanical properties necessary to be a good material for structural fill and embankments. In structural fill, foundry sand is typically placed in lifts and compacted to form the base for a building, roadway or other structure.
plex shapes, excellent vibration damping properties, and so forth, polymer concrete materials have also been extensively used for applications other than for which these were origi-nally developed. Use of polymer concrete has been reported in electrical insulation systems [,]aswellasmachinetool
