Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to longduration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft).
Dredged soil is solid waste generated from the dredging of a river. It exhibits low bearing capacity and high compressibility and poses severe health and environmental problems. D

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soilcement, and in new concrete.
ASTM''s cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

The materials that were used for the study were Portland cement, ground waste clay brick (GWCB), sand, water and a chemical admixture. The Portland cement was a type I/II cement that conformed to the ASTM C150 obtained from Ashgrove, Chanaute, United States. The GWCB was obtained from the brick factory of CSIRBRRI in Ghana.
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and nonspecialty was developed from other types of hydraulic lime in England in the mid 19th century, and usually originates from is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the ...
In Europe the use of cement and concrete (a mixture of cement, aggregates, sand and water) in large civic works can be traced back to antiquity. In 2008 there were 268 installations producing cement clinker and finished cement in the European Union with a total of 377 kilns [4].
