Concrete and Embodied Energy - Can using concrete be ...

ABSTRACT: Data on the dynamic fracture energy of concrete are scarce and also not consistent due to dif-ferent test methods, data analyses and definitions. This paper intends to facilitate the discussion on dynamic fracture energy and start the standardization process for dynamic tensile testing. The response and failure mechanisms in statics and dynamics are addressed. Definitions of the ...

Energy Efficiency and Saving in the Cement Industry ...

In the cement/concrete industry improvement of energy efficiency and reduction of CO 2 emissions could be mainly achieved through two procedures: (i) by changes in the manufacturing and production processes, and (ii) by adjusting the chemical composition of cement. Manufacturing and production processes can be improved by changing energy management and by investing in new equipment …

Energy Consumption Benchmark Guide: Cement Clinker Production

steadily away from less energy-efficient wet process kilns toward the more fuel-efficient dry process kilns. The number of wet process kilns in production declined by more than 50 percent between 1990 and 1998. As of May 1999, only two wet kilns were still operating in Canada. The industry has achieved additional energy efficiency gains by using preheaters and precalciners. These technologies ...

Energy consumption reduction in concrete mixing …

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.

Today in Energy - Energy Information Administration

Energy-intensive manufacturing accounted for a little more than half of total industrial energy use. Although the cement industry used only one-quarter of one percent of total U.S. energy, it is the most energy-intensive of all manufacturing industries, with a share of national energy use roughly 10 times its share of the nation's gross output of goods and services .

Concrete - Wikipedia

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

How Cement Is Made

Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden.
