Properties of Fresh Concrete When concrete is its plastic state it is known as fresh concrete. Fresh concrete can be easily moulded to a durable structural member. Following are the properties of fresh concrete. Workability Segregation Bleeding Plastic shrinkage Setting Temperature Water Cement Ratio Workability The term workability indicates the ease or difficulty with which …
What is Concrete? Concrete is the mixture of cement, sand, aggregates and water. Cement concrete is the major building material in the construction industry. It can be easily moulded into durable structural members. In concrete sand is used as fine aggregates, gravels and crushed stones are used as coarse aggregates. The cement acts as a binding …

What is Water Cement Ratio? The ratio of the amount of water to the amount of cement by weight is termed the water-cement ratio. The strength and quality of concrete depend on this ratio. The quantity of water is usually expressed in litre per bag of cement. if water required for one bag of cement is …

What Is Workability of Concrete? The term workability indicates the ease or difficulty with which the concrete is handled, transported and placed. The amount of water present in concrete should be in the proper ratio. Generally, a higher water-cement ratio is required for good workability. In the actual function of water is to lubricate the concrete. …
What is the Compressive Strength of Concrete? Compressive strength of cement concrete is the strength of concrete against crushing due to direct compressive load. It is considered to be the most important property of concrete and is often taken as the index of the overall quality of the concrete. Factors Affecting Compressive Strength of Concrete …

Concrete Cement concrete may be defined as building material obtained by mixing cement, sand, aggregates and water in suitable proportion and then curing this plastic mixture to a hard mass. It can be easily moulded to durable structure members. The volume of aggregates in concrete varies from 60 to 78%. What is Grade of Concrete? …

What is Admixtures? Admixtures are material used in concrete to modify its properties. Admixtures are materials other than cement, aggregate, and water that are added to concrete either before or during its mixing to alter its properties such as workability, curing temperature range, set time or colour. Some admixtures have been in use for a …
