Mostly concrete structures are failed due to poor workmanship which is a very tricky factor to control. Structures build with concrete has a life both from serviceability point of view and from structural point of view and this life depends solely on the quality of the material while placing.The quality of concrete is tested by … Read more
Abrasion is known as process of scraping or wearing something away, technically speaking; abrasion in geology is the mechanical scraping of a rock surface by friction between rocks and moving particles during their transport by wind, waves, gravity, running water or erosion. The intensity of this erosion effect depends on the hardness, concentration, velocity and … Read more
Sand replacement test method is used to determine the field density or in-place density of earth embankments, road fills, sub-grade, sub-base or any of compacted material. This method serves as base upon which one can accept the density of a compacted material to a specified magnitude or to a percentage of maximum unit dry density … Read more
To study about materials is very essential for civil engineers. Civil Engineers deal with variety of materials like concrete, cement, aggregates, soil, bricks and various others that are used to construct or to support some structural load. The ultimate destination of load for any structure is soil. Soil absorbs as well as dissipates the load … Read more
@import url(http://fonts.googleapis.com/css?family=Oswald:700); The limit of water absorption by coarse aggregates is determined so as to calculate the appropriate amount of water to be added to the concrete mix, thus modifying the water cement ratio. A bone dry aggregate would necessitate, while for wet aggregate water contents should be reduced. \”Determine the water absorption by coarse … Read more
