In this context, the volume of used foundry sand is such that the disposal creates a big environmental problem for all the countries where the foundry industries are in abundance. New methodologies should be employed to utilize the used foundry sand in making value-added products in a commercial manner to keep the environment free from the potential adverse effects of the accumulation of this waste product. This research is an attempt to put forward the idea of utilizing the used foundry sand in commercial production of value-added products like paver blocks from a techno-economical point of view. This will be beneficial to the ecological and environmental systems for sustainable development progressing towards a greener world.

The majority of the industries are not interested in the treatment and safe disposal of the industrial waste due to its high cost involvements to reduce the toxic and other chemical contents to a safer level before dumping over to land. In this context the disposal of waste foundry sand is of prime importance due to the big volume produced from the foundries all over the world. Foundry sand which is basically high quality silica sand is disposed of after the initial use for least benefitted land filling usage causing environmental and other ecological impacts. For infra structure developments there needs buildings, bridges,roads and other structures and concrete plays a vital role in these civil construction activities.The mother earth is over exploited for the procurement of construction materials for development works.It is high time to think of alternative materials particularly from the industrial waste products for construction activities for preserving the natural resources to the future generations too. It was inferred that about 20 to 30 percent of replacementof fine aggregate to used foundry sand gave good results in most of the applications. Thus used foundry sand can be economically utilized as a partial or full replacement to fine aggregates for concrete or mortar making and thereby reducing the usage of fresh fine aggregates and to minimize the exploitation of natural resources to a minimum balanced state with reduced ecological impact.

In this project the durability properties of concrete made with pulverized used foundry sand as a mineral admixture is analyzed. The durability of concrete is mostly depends on the surrounding environment. The chemicals present in air and water are the main causes of deterioration of concrete in its life. So a deep study on the action of deteriorating chemicals on the concrete containing pulverized used foundry sand is initiated. Here M40 concrete is prepared with 0%,5%,10%,15% and 20% addition of pulverized used foundry sand to the cement content. Cubes of size 100mmx100mmx100mm were cast and tested for various parameters like Acid resistance with hydrochloric acid and sulfuric acid, Sulphate attack with sodium sulphate and alkali resistance with sodium hydroxide for. The testing was performed on cubes at 28day, 56 day, 90 day and 180 day stored in respective chemicals dissolved in water at 5% concentration. From the test results it is inferred that the concrete containing pulverized used foundry sand is better in acid resistance than ordinary concrete without pulverized used foundry sand. Further the acid resistance for both hydrochloric and sulfuric acid shows an increase up to 15% addition of pulverized used foundry and after that it is slightly reduced. The samples subjected to sodium sulphate and sodium hydroxide has shown no variation in properties with respect to the water cured specimens.

Since the inception natural sand is used as the fine aggregate for the production of concrete. Due to the large scale infrastructure development activities all over the world the availability of natural sand is decreasing day by day. In the case of manufactured sand also there exist restrictions in large scale production due to environmental and ecological impacts. All these affect the production of concrete a big concern in which natural sand or manufactured sand is used as fine aggregate. In the mean time industrial wastes are accumulating at an alarming level. Used foundry sand is one such kind of industrial waste product with high volume availability. The used foundry sand can be used in making high performance concrete as a partial substitution of fine aggregates. This will be helpful for the safe disposal of this industrial waste and for reducing the exploitation of natural resources to a greater extent. In the present study the properties of high performance concrete made with used foundry sand in partial replacement of fine aggregates as available from various published researches is analyzed.

Mineral admixtures are widely used in the production of concrete for enhancing the strength and durability properties. The mineral admixtures commonly available are fly ash, metakaolin, rice husk ash, silica fume. In this project absorption and permeability characteristics of concrete made using Pulverized Used Foundry Sand (PUFS) is discussed in detail. The absorption and permeability characteristics have great importance on the durability of structures. These characteristics have wider impacts on reinforced concrete structures than plain concrete structures. M 40 concrete was made with PUFS content at 0%, 5%, 10%, 15% and 20% to that of the cement content. Specimens were casted and cured in water for the required duration. Then the tests were conducted as per standard procedure. The concrete made with the addition of PUFS showed better results than the normal concrete without using PUFS. Further an addition of PUFS in the range 10-15% of the cement content gives good concrete with least absorption and least permeability.

The history of the construction of concrete bridges in India is century old. In the case of construction of pre stressed concrete bridges also India has got a prominent role. In older days technology was not much developed and manual means were much implemented for the construction of bridges. Nowadays construction methodologies have been changed widely and sophisticated machineries are introduced which made the labour input to a minimum. But the overall construction cost is on the high. The main reason for the high overall construction cost is the lack of study at the planning stage. Subsequently all the flaws are cumulated and resulted in the high construction cost. This can be reduced to a great extent by implementing optimization techniques particularly in the planning and design stages. As far as a particular bridge site is concerned the unit cost of material, labour and machinery etc. are constant. So the cost effectiveness can only be achieved by the optimization of the design in consideration with the site related parameters. In this study the various factors which influence the higher cost of construction are elaborated and a real time approach to reduce the overall construction cost are discussed with. Apart from the cost considerations this will be particularly beneficial to the sustainable development by the minimum use of materials and energy thus preserving the ecology and environment to a possible extent. From this study it is inferred that the overall construction cost can only be achieved by utilizing the piles at its maximum capacity and the span length should be decided based on the various combinations of number of piles in a group.

The recycled sand obtained from industrial operations can also be utilized in construc tion activities. Many industries generate waste sand as a byproduct. The material generated from this discarded molds and cores is usually known as "used foundry sand," "waste foundry sand," or "spent foundry sand." A vast quantity of used foundry sand is generating and heaping globally in a day-by-day manner. In this review article, an attempt is made to explore the characteristics and various utilizations of this recycled sand from the foundry industry as a valuable resource material in construction activities. From the analysis of the multiple types of research done so far on the reuse of waste foundry sand, it is found that the waste foundry sand is reusable in different civil engineering applications with added advantages. The advantageous applications of used foundry sand are ranging from the road base material to the substitute to fine aggregate in high-performance self-compacting concrete. More generally used foundry sand in the range of 10-30% is best suitable as a partial substitute to regular sand in mortar and concrete making. The use of recycled sand such as waste foundry sand in the construction industry can not only eliminate the problems of waste management and environmental impacts but also substantially boost up the sustainable developmental activities by way of reducing the consump tion of natural resources.
