The uses of special types of concretes are as follows.
i) Vacuum concrete: It is the concrete in which entrained air and excess water form concrete mix is taken out from vacuum pump, called vacuum concrete.
Use: i. Industrial floor sheds. ii. Hydro power plants iii. Bridges, ports and harbours iv. Cooling towers
ii) Fiber reinforced concrete: The concrete made up of using one or more type of fibers in the concrete mix, is known as fiber reinforced concrete.
Use: i.Construction of air field, road pavements, industrial floorings, bridge decks, etc. ii.Useful in canal lining, refractory lining. iii.Useful in fabrication of precast products like pipes, boats, beams, staircase steps, wall panels etc. iv.Applicable in construction of explosive resistive structures.
iii) High performance concrete: The high performance concrete is a concrete in which certain characteristics are developed for a particular application and environment, so that it will give excellent performance in the structure to be built, is called as High performance concrete.
Use: i. Construction of special structures like atomic power stations, satellite launching station, heavy duty runway, etc. ii. Mass concrete structures like dams, long span bridges, etc.
iv) Self-compacting concrete: It is the concrete which settle down under its own weight so that it does not require any type of external vibration for its compaction.
Use: i. Thin walled structures like pardi, retaining wall etc. ii. Highly reinforced sections i.e. large bridge and machine foundations iii. Pumped concrete for floors and slabs. iv. Pre-stressed concrete
