bricks, fly ash, granite waste powder and lime was used as raw material, Fly ash bricks were manually casted, air dried 7, 14, 21 days compressive strength and percentage of water absorption was determined. Even the study involves the computation of embodied energy for the clay and fly ash bricks. Key words: Compressive Strength, Water Absorption, Embodied Energy I. INTRODUCTION
The embodied energy is the energy requirement to construct and maintain the premises, for example, with a brick wall, the energy required to make the bricks, transport them to site, lay them, plaster them and (if necessary) paint and replaster
Green Patio Options: Brick, Stone, Gravel, Concrete and Recycled Materials. These materials' high embodied energy and the environmentally destructive production practices used to create them are cause for concern. Hard, nonporous cement and asphalt offer undeniable durability, but they also hinder stormwaterrunoff absorption and add toxins to your environment during installation.
energy used in material production: steel, cement, paper, plastics and aluminium. We then estimate the possibility of reducing absolute material production energy by half, while doubling production from the present to 2050. The goal therefore is a 75 per cent reduction in energy intensity. Four technology
Tumbling is a process of smoothing and polishing a hard substance like stone. For tumbling of stones a rubber barrel is loaded with consignment of rocks, abrasive grit and a lubricant. The barrel is then placed on slowly rotating rails and the stones are gradually smoothed and polished.

The term 'embodied carbon' refers to the lifecycle greenhouse gas emissions (expressed as carbon dioxide equivalents – CO. 2. e1) that occur during the manufacture and transport of construction materials and components, as well as the construction process itself .
Different theories of embodied energy locate the system boundary differently, resulting in a different methodology. Specification of the system boundary is an important part in identifying the root definition influencing one's choice of embodied energy methodology.
Gross Energy Requirement (GER) is a measure of the true embodied energy of a material. In practice this is usually impractical to measure. Process Energy Requirement (PER) is a measure of the energy directly related to the manufacture of the material. This is simpler to quantify.
The third sheet is the individual material embodied energy values with a long list of the websites where these numbers were harvested. The embodied energy of a "raw" material like stone or sand is very location dependent as it is minimally processed, so the shipping costs predominate. Highly processed
embodied energy, about 19,900 Btu per ton for sand and gravel, and about 30,500 Btu per ton for crushed stone. Thus, the embodied energy depends largely upon the proportion of cement to aggregate in a given concrete mix. The embodied energy of concrete brick is MBtu per cubic yard. The typical embodied
Key points. The usual range employed is between and in diameter. Fine aggregates are usually sand or crushed stone that are less than in diameter. • Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete.
The sum of all energy embedded in products and processes used in constructing a building is known as embodied energy. According to the literature, the current state of embodied energy research suffers from three major issues. First, there is little agreement on the definition of embodied energy. Second, the
In calculation, the embodied energy of fly ash is less as compare with cement. But if we compare embodied energy of crushed glass with sand, there is a huge difference. So when we use crushed glass in formation of concrete, the embodied energy of that concrete get increased and the testing results of use of crushed glass are not so good.
LP Embodied energy can be split into: (1) energy consumed Steel in the production of basic building materials, (2) energy Aluminium Glass needed for transportation of the building materials, and (3) Venkatarama Reddy, Jagadish / Energy and Buildings 35 (2003) 129–137 131 LP cements can provide very effective alternative to for the comparison and computation of energy .
density, hardness, porosity, and aesthetics. Users should verify that the granite they plan to use is applicable to the demands of the project and has a successful history in such installations. ASTM test data is the most common data available to compare the properties of any stone, including granite.
