Civil Engineering Reinforced cement concrete
Cement is a fine powder that, when combined with water, undergoes a chemical process called hydration, leading to the formation of a robust and enduring material known as concrete. Cement has been utilized for centuries, and its significance in contemporary infrastructure development cannot be emphasized enough. History of Cement:
Grade of Concrete and it's Modular Ratio Civil Engineering Grade of concrete, Civil
concrete, in construction, structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel), that is bonded together by cement and water. Among the ancient Assyrians and Babylonians, the bonding substance most often used was clay.

1. Concrete Dams The characteristics of concrete such as high strength and unit weight make it a more suitable material for the construction of dams. Dams are used to store water and produce electricity. The loads imposed on the dam due to water pressure are very intense which makes concrete as a suitable material for dam construction.

Concrete Definition: Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate ( sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.

Cement is a fine-grained construction material composed of limestone, clay, shale, and other materials. Cement is not often used on its own but instead acts as a binder that secures other materials together. Builders use cement because of its ability to harden and support heavy structures and withstand harsh weather conditions.
10 Types of Cement โ Civil Engineering Profile
1. High alumina cement is obtained by fusing or sintering a mixture in suitable proportion of alumina and calcareous material and grinding the resultant product to a fine powder. 2. Raw materials are limestone and bauxite. 3. About 20% of strength is achieved in one day.

Cement is a construction material which is used as a binder. It binds other construction material aggregate and sand together. Cement exhibits different properties if we change the chemical composition. Earlier the different types of cement was found by only varying the relative proportion of the oxide composition.As time advances, new materials like additives to.
