And a material becomes useless when any void present in the material.If the cement covered by extreme moisture content due to bad weather conditions, then the specific gravity of cement may go up to 3.If the specific gravity value reaches 3.19, then the pores in cement are filled with the moisture.
The Acoustic Emission (AE) technique is currently used during experimental tests to investigate on the damage evolution in ductile or brittle materials before the final failure , .The spatio-temporal evolution of ultrasonic AE signals, also known as “crackling noise” when they occur in the audible field, is a direct result of cracking bonds during the fracture of materials.

Cement is the basic ingredient of construction and the most widely used construction material.It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
Cement paste (cement mixed with water) sets and hardens by hydration, both in air and under water.The main base materials for Portland cement, are limestone, marl and clay, which are mixed in defined proportions.This raw mix is burned at about 1450 C to form clinker which is later ground to the well-known fineness of cement.

Civil Concrete Technology Lectures Notes Concrete Definition In its simplest form, concrete is a mixture of paste and aggregates (rocks).The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates.Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known .
Clinkerisation is the heart of cement manufacturing process, where the raw material is fed to pre-heater at controlled rate through electronic weigh feeder.The feed enters the kiln through cyclones and fuel is fired at the kiln outlet end.
Concrete is a common material used in a wide range of construction projects.It is used in setting fence posts, pouring driveways and even laying the foundation for a home.

Step 1 – Quarrying Limestone and a 'cement rock' such as clay or shale are quarried and brought to the cement works.These rocks contain lime (CaCO3), silica (SiO2), alumina (Al2O3) and ferrous oxide (Fe2O3) - the raw materials of cement manufacture.
The dry material undergoes a series of chemical reactions in the hottest part of the kiln and some 20 to 30 percent of the material becomes liquid, and lime, silica and alumina recombine.The fused mass turns fuses into balls of diameter 3 to 25 mm known as clinker.The clinker drops into coolers where it is cooled under control condition.
