2015/7/2To drain soil waste water to septic tanks or town sewers. The principal types of pipes that are available in the market to serve the above mentioned purposes are as follow. Cast iron pipes and fitting Plastic or PVC pipes Galvanized steel (GI) pipes 1. WHAT IS GREEN CONCRETE? Today the word green is not just limited to colour, it represents the environment, which is surrounding us. Concrete which is made from concrete wastes that are eco-friendly are called as "Green concrete". The other name fo
Bituminous Concrete (BC) is a composite material mostly used in construction projects like road surfacing, airports, parking lots etc. It consists of asphalt or bitumen (used as a binder) and mineral aggregate which are mixed together laid down in layers then
fit for usage as coarse aggregate. This makes glass a potential material for usage as a coarse aggregate. Waste glasses are used as aggregates for concrete [7,8,9]. Topcu and Canbaz  concluded that when waste glasses are reused in making concrete
Some byproduct material is useful because of self-luminous qualities (e.g., exit signs, watch dials), and other byproduct material is used in medical practices for diagnosis or therapy. Although the EPAct was effective on August 8, 2005, the NRC did not have regulations in place that would specifically apply to the newly defined byproduct material (hereafter referred to as NARM).

• The waste plastic used for experiments is of LDPE (Low Density Poly Ethylene), type of 20 size with fineness modulus value of 7.59 and specific gravity of waste plastic is found to be 1.1. • The compressive strength of RPC is compared with plain concrete (fig 1

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.
Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption, but also pollutant emissions. Take for example Burj Kalifa in Dubai, the world's tallest tower. It required 45,000 m of concrete for for all
E-Waste Recycling: E-waste or electronic waste is the waste generated by electronic items like calculator, mobile phone, watches, remote, laptop, tablet and many more. These wastes are hazardous in nature and therefore should better be recycled.
The increased national interest in constructing green buildings is likely to generate more interest in recycling CD materials. Providing knowledge of how to recycle construction and demolition materials can make you a vital asset to a green building project. The
E-waste or electronic waste means old and unused electronic items like radio, TV, mobile phone, refrigerator. This is a very good and profitable recycling business idea. Recycling them is good for the environment as these devices contain harmful substances like phosphorous, lead, cadmium, etc. which are very harmful to the environment.
The using of waste materials in the construction industry can reduce the dependence on the natural aggregates which are going at the end to deplete. The glass waste is generated in a huge amount which can make one of its disposals in concrete industry effective not only as a green solution but also as an advantage to enhance the performance of mechanical properties and durability of concrete
Current environmental awareness compels all citizens to reduce the production of waste and use recycled materials. Recycled materials coming from construction and demolition (Camp;D) waste are progressively being used in civil engineering applications, such as base and sub-base layers of transport infrastructures and concrete production. However the fine grain fraction of Camp;D recycled
One of the main alternatives to which recycling is compared is the disposal of the recyclable waste in landfills. Since no sorting or processing is required beyond transporting the waste to the landfill, it appears at first glance that landfill disposal is cheaper: it requires less money for human labor and less energy for work done by machines.
2008/11/1A concrete mixture made of 20% waste plastic has the lowest flexural strength at 28 days curing age, viz. 30.5% below the value of the reference concrete mixture. The dry density values of waste plastic concrete mixtures at each curing age tend to decrease below values for the reference concrete mixture, but they remain averaged to that of the reference concrete mixtures.
this waste is use of the material in Concrete-A widely used material. In this paper an attempt is made to study the various properties of rubber. An attempt to design concrete of 25Mpa using artificial sand, Shredded rubber and crumb rubber as a source of
Concrete strength Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed.
essential to develop profitable building materials from hypo sludge. The cement has been replaced by waste paper sludge accordingly in the range of 0% (without Hypo sludge), 7.5%, 10%, 15% by weight. Concrete mixtures were produced
Types of Waste In order to help reduce waste in the U.S. health care system, we first must understand the sources of the problem. While many studies have examined different types of waste, there has been, to date, no comprehensive conceptual framework to
