·Cement is a fine grey although it may be off white or white powder made of a mixture of calcined limestone and clay used with water and sand to make mortar or with water sand and aggregate to make concrete When hardened it is concrete that is the resulting stone like mass It is important to understand the difference between cement and concrete

·Cement quality is typically assessed by its compressive strength development in mortar and concrete The basis for this property is a well burned clinker with consistent chemical composition and
The results showed that compared with the sample prepared with dense aggregates the sample prepared with hollow spheres had a % higher cold compressive strength % higher modulus of
·Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products The lumps or nodules of clinker are usually of diameter 3 25 mm and dark grey in color It is produced by heating limestone and clay to the point of liquefaction at about 1400°C 1500°C in the rotary kiln
Sampling is frequently used because gathering data on every member of a target population or every product produced by a company is often impossible impractical or too costly to collect Sampling lets you draw conclusions or make inferences about the population or product lot from which the sample is drawn Figure 1 Figure 1 Sampling Example
A complete bond exists between the steel and the concrete; that is the strain in the steel is the same as in the adjacent concrete Tension stress in the concrete is negligible that is all tension is resisted by steel The ultimate strain in concrete is In a properly designed beam the tension steel yields; thus T = Asfy

·1 Introduction Nowadays cement manufacturing is an energy intensive industry The energy costs of cement industry are about 40% of the product cost that indicates that this sector is one of the biggest CO 2 emitter The global anthropogenic CO 2 emission of cement industry is approximately 5% [] The International Energy Agency reported in 2011 that
An operations audit should be carried out whenever important changes of a general nature are considered Some important changes may include a plant wide cost reduction effort the installation of a productivity program thermal energy efficiency program electrical energy efficiency program chemistry and operations strategy the introduction of new products
