Alternative Fuel Use in Cement Manufacturing
Alternative Fuel Use in Cement Manufacturing iii thermal energy requirements and chemical process required to produce clinker, the active component in cement. The difference between cement and concrete Although the terms cement and concrete are often used interchangeably, cement is actually an ingredient of concrete. Concrete is a mixture
Technologies that Reduce Water use in Cement and Concrete
Water consumption during Portland cementbased concrete curing. Concrete is the second most consumed substance in the world, as mentioned above. Portlandcementbased concrete is made by mixing aggregates (both coarse and fine), ordinary Portland cement (OPC), admixtures (mineral or chemical), and water.
Manufacturing Energy Consumption Survey (MECS)
Energy use in the steel industry has been declining. A ten year historical trend (19912002) of the steel industry indies that there has been a 38 percent decline in the total energy consumption used in the industry ().The largest portion, 34 percent of the decline in the total energy consumption occurred between 1998 and 2006.
Top 16 Mistakes People Make When Installing Concrete
Everything from the mix design, quantity of concrete to purchase, site preparation, tools, weather forecast, placement process, form removal and curing process need to be Continue reading "Top 16 Mistakes People Make When Installing Concrete"
Energy Consumption in Production of Concrete
Aug 28, 2017 · The production of 1 m³ of concrete requires 2,775 MJ of energy. This energy comes mostly from oil burning, which generates CO2. 2.775 MJ of energy is produced by 0.37 barrels of oil. Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption, but also pollutant emissions.
Energy Cost
Construction materials such as concrete, brick and woods require relatively little energy to produce them and are thus cheap Metals are usually extracted from their oxide this takes up a lot of energy, for example, one twentieth of the total energy consumption in the United States is used to produce aluminium. Example Uses
Concrete and Embodied Energy Can using concrete be
Concrete is the most widely used building material in the world. There is now approximately 2 tonnes of concrete for each person on the planet earth. The small amount of embodied energy (carbon) in one tonne of concrete, when multiplied by the huge amount of concrete used, results in concrete
Production of Precast Concrete Sustainable Precast
A large number of castings in forms is typical in the production of precast concrete elements in plants with savings of raw materials. Plywood form use is limited to about 20 to 50 castings depending upon the complexity, maintenance and shape of the form. Standardized elements cast in steel forms are one step towards sustainable production.
The Environmental Impacts of Concrete
• Of the total CO 2 output, 30% derives from the use of energy and 70% results from decarbonation • Important to realise is that although 5% of the worldwide generation of CO 2 is due to cement production, that level of output also reflects the unique and universal importance of concrete throughout the construction industry.
Energy consumption reduction in concrete mixing process by
Mixing process plays a very important role in the concrete microstructure which defines the quality of the final product. The improvement of energy efficiency during this process can help to reduce energy consumption and production costs, without affecting product quality.

Precast Concrete Floor, Wall and Frame Construction Process
Primary elements of precast concrete construction consists of frame, walls and floors. Precast concrete provides time and cost benefit to the project and better quality control than onsite concrete construction. Precast concrete construction has many advantages over castinsitu concrete structures
Energy and Cost Analysis of Cement Production Using the
The study evaluates the energy consumption of both wet and dry processes cement manufacturing plant in Nigeria. En ergy consumption data collected for the period 2003 to 2011 were used to estimate the energy consumption of the crushing, milling, agitation, burning, grinding and bagging operations. The total energy evaluation was based on the

FACT SHEET Energy use in the steel industry
Steel use is projected to increase steadily in the coming years to meet the needs of our growing population. Energy use in steelmaking Steel production is energy intensive. However, sophistied energy management systems ensure efficient use and recovery of energy throughout the steelmaking process for use within the steelworks
Energy consumption and energy efficiency
In return for energy tax relief, German industry has – in place of the previous climate protection agreement – committed to introducing certified energy management systems and a collective annual reduction in specific energy consumption of 1.3 per cent
Energy Efficiency and Saving in the Cement Industry
The main potential in reducing energy consumption and CO 2 emissions from cement/concrete production is in improvement of cement pyroprocessing. Pyroprocessing transforms the raw mix into clinkers. At present, about 78% of Europe's cement production is from dry process kilns, a further 16% of production is accounted for by semidry and semiwet process kilns, with the remainder of European
Concrete for energy efficient buildings
It is crucial to reduce energy consumption in buildings because of the significant role this can play in combating unsustainable levels of energy use. European figures show that the energy used for the heating, lighting and cooling of buildings accounts for over 40% of the primary energy consumed.
Energy Usage and Greenhouse Gas Emissions of Pavement
Tables 2 and 3 are summaries of total energy use and GHG emissions for raw materials, manufacture, transport, and placement of various construction products (Chappat and Bilal, 2003). The data shows that Portland cement concrete pavements use the highest energy consumption at
Energy Use by Buildings and the Built Environment
Those energy uses really fall into the area of building energy consumption (as opposed to the process of making steel or glass, for example). There is also a portion of industrial energy consumption that has to do with construction materials—the energy it takes to make the stuff we use in buildings houses and commercial buildings.
Evaluation of energy consumption during production and
Oct 15, 2016 · Energy consumption during production and construction (PAC) of buildings' frames is evaluated. • Production of materials/components consumed 90% of energy during PAC of buildings' frames. • Energy consumption during PAC of concrete

Energy Efficiency Improvement and Cost Saving
The production of cement is an energyintensive process. Typically, energy consumption accounts for 2040% of production costs. In 2008, the U.S. cement industry spent about $1.7 billion to purchase energy around $0.75 billion of this was for electricity and $0.9 billion for fuels.
Concrete Wikipedia
The overall embodied energy of concrete at roughly 1 to 1.5 megajoules per kilogram is therefore lower than for most structural and construction materials. Once in place, concrete offers great energy efficiency over the lifetime of a building. Concrete walls leak air far less than those made of wood frames.
