reducing industrial energy costs through energy efficiency measures in a liberalized european electricity market case study of a swedish iron Foundry
Applied Energy, 2005Co-Authors: Patrik Thollander, Magnus Karlsson, Mats Soderstrom, Dan CreutzAbstract:Swedish industry, which has one of the lowest electricity prices in the European Union, will face higher electricity prices due to the Union's electricity market liberalization. Rising electricity prices, together with a larger use of electricity than other European countries, pose a threat to industrial activity in Sweden. The Swedish Foundry industry, with large proportions of energy costs in relation to the added value, is particularly sensitive to higher electricity costs. The aim of this paper is to study the effect of higher electricity prices on the Swedish iron-and-steel Foundry industry, quantify an energy efficiency potential for a medium-sized Swedish iron Foundry resulting from a thorough industrial energy audit, and investigate what impact they have on the energy cost.

properties of concrete containing fungal treated waste Foundry sand
Construction and Building Materials, 2012Co-Authors: Gurdeep Kau, Rafa Siddique, Anita RajoAbstract:Abstract Waste Foundry sands represent the highest amount of solid wastes generated by foundries. The high cost of land-filling and the potential uses of waste Foundry sand in construction purposes have prompted research into their beneficial reuse. For high-performance construction materials microbial (bacteria/fungi) modified concrete has become an important area of research. This study investigates the effects of incorporating fungal treated waste Foundry sand (WFS) on concrete. Results present the effect of Aspergillus spp. on compressive strength, water absorption and porosity of concrete containing waste Foundry sand. The study shows that 15.6% increase in compressive strength of concrete after 28 days was achieved with the addition of fungal ( Aspergillus spp.) treated 20% WFS containing concrete and also shows decrease in water absorption (68.8%) and porosity (45.9%). X-ray diffraction (XRD) results suggest that fungal culture ( Aspergillus spp.) is capable to form good C–S–H gel than untreated concrete containing WFS, which shows that Aspergillus spp. increase the ability of cement to react properly with Foundry sand and hence due to which C–S–H gel formation increases. Silica present in WFS is consumed to form C–S–H gel, which in turn hardened the fungal treated waste Foundry sand containing concrete.

utilization of waste Foundry sand wfs in concrete manufacturing
Resources Conservation and Recycling, 2011Co-Authors: Rafa Siddique, Gurpree SinghAbstract:Abstract Due to ever increasing quantities of waste materials and industrial by-products, solid waste management is the prime concern in the world. Scarcity of land-filling space and because of its ever increasing cost, recycling and utilization of industrial by-products and waste materials has become an attractive proposition to disposal. There are several types of industrial by-products and waste materials. The utilization of such materials in concrete not only makes it economical, but also helps in reducing disposal concerns. One such industrial by-product is waste Foundry sand (SFS). Waste Foundry sand is a by-product of ferrous and nonferrous metal casting industries. Foundries successfully recycle and reuse the sand many times in a Foundry. When the sand can no longer be reused in the Foundry, it is removed from the Foundry and is termed as waste Foundry sand. Published literature has shown that WFS could be used in manufacturing Controlled Low-Strength Materials (CLSM) and concrete. This paper presents an overview of some of the research published on the use of WFS in concrete. Effect of WFS on concrete properties such as compressive strength, splitting tensile strength, modulus of elasticity, freezing-thawing resistance, and shrinkage are presented.

strength durability and micro structural properties of concrete made with used Foundry sand ufs
Construction and Building Materials, 2011Co-Authors: Rafa Siddique, Yogesh Aggarwal, Paratibha Aggarwal, El-hadj Kadri, Rachid EnnaceAbstract:Abstract This paper presents the design of concrete mixes made with used-Foundry (UFS) sand as partial replacement of fine aggregates. Various mechanical properties are evaluated (compressive strength, and split-tensile strength). Durability of the concrete regarding resistance to chloride penetration, and carbonation is also evaluated. Test results indicate that industrial by-products can produce concrete with sufficient strength and durability to replace normal concrete. Compressive strength, and split-tensile strength, was determined at 28, 90 and 365 days along with carbonation and rapid chloride penetration resistance at 90 and 365 days. Comparative strength development of Foundry sand mixes in relation to the control mix i.e. mix without Foundry sand was observed. The maximum carbonation depth in natural environment, for mixes containing Foundry sand never exceeded 2.5 mm at 90 days and 5 mm at 365 days. The RCPT values, as per ASTM C 1202-97, were less than 750 coulombs at 90 days and 500 coulombs at 365 days which comes under very low category. Thereby, indicating effective use of Foundry sand as an alternate material, as partial replacement of fine aggregates in concrete. Micro-structural investigations of control mix and mixes with various percentages of Foundry sand were also performed using XRD and SEM techniques. The micro-structural investigations shed some light on the nature of variation in strength at the different replacements of fine aggregates with Foundry sand, in concrete.

effect of used Foundry sand on the mechanical properties of concrete
Construction and Building Materials, 2009Co-Authors: Rafa Siddique, Gee De Schutte, Albe NoumoweAbstract:Abstract Used-Foundry sand is a by-product of ferrous and nonferrous metal casting industries. Foundries successfully recycle and reuse the sand many times in a Foundry. When the sand can no longer be reused in the Foundry, it is removed from the Foundry and is termed used/spent Foundry sand. In an effort to utilize used-Foundry sand in large volumes, research is being carried out for its possible large-scale utilization in making concrete as partial replacement of fine aggregate. 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 30%) of UFS by weight. Tests were performed for the properties of fresh concrete. Compressive strength, splitting-tensile strength, flexural strength, and modulus of elasticity were determined at 28, 56, 91, and 365 days. Test results indicated a marginal increase in the strength properties of plain concrete by the inclusion of UFS as partial replacement of fine aggregate (sand) and that can be effectively used in making good quality concrete and construction materials.

utilization of spent Foundry sand in controlled low strength materials and concrete
Resources Conservation and Recycling, 2008Co-Authors: Rafa Siddique, Albe NoumoweAbstract:Abstract With ever increasing quantities of industrial by-products and waste materials, solid waste management has become the principal environmental concerns in the world. Scarcity of land-filling space and due to its ever increasing cost, utilization/recycling of by-products/waste has become an attractive alternative to disposal. Several types of by-products and waste materials are generated. Each of these waste products has specific effects on the properties of cement-based materials (CLSM and Concrete). The utilization of such materials in concrete/CLSM not only makes it economical, but also do help in reducing disposal problems. Reuse of bulk wastes is considered the best environmental alternative for solving the problem of disposal. One of such industrial by-products is Spent Foundry Sand (SFS). Spent Foundry sand is a by-product of ferrous and non-ferrous metal casting industries. Foundries successfully recycle and reuse the sand many times in a Foundry. When the sand can no longer be reused in the Foundry, it is removed from the Foundry and is termed as spent Foundry sand. Published literature has shown that SFS could be possibly used in manufacturing Controlled Low-Strength Materials (CLSM) and concrete. This paper presents an overview of some of the research published on the use of SFS in controlled low-strength materials and concrete. Effect of SFS on CLSM characteristics like plastic properties, compressive strength, permeability, and leachate analysis, and concrete properties such as compressive strength, splitting tensile strength, modulus of elasticity, freezing–thawing resistance, and shrinkage are presented.
