Free fall in concrete refers to the process of pouring concrete without any external force to assist in its placement.

• Free fall is a method of placing concrete where it is allowed to fall from the mixer truck or pump without any external force.

• This method is used for small jobs or in areas where access is limited.

• It can result in segregation and air pockets in the concrete if not properly managed.

• Free fall height should be limited to 1.5 meters to prevent segregation.

• Vibrator...read more

Embedded length is the length of a reinforcing bar that is embedded in concrete.

• It is the length of a reinforcing bar that is embedded in concrete

• It is used to provide anchorage to the reinforcement in the concrete

• The length is determined by the diameter of the bar and the strength of the concrete

• It is important to ensure that the embedded length is sufficient to prevent failure of the structure

Grade of concrete refers to the strength of the concrete mix.

• Grade of concrete is denoted by the ratio of cement, sand, and aggregate used in the mix.

• The strength of concrete increases with the increase in the grade of concrete.

• For example, M20 grade of concrete means the mix contains 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• Higher grade of concrete is used for structures that require higher strength, such as bridges and high-rise buildings.
