Lightweight concretes can either be lightweight aggregate concrete, foamed concrete or autoclaved aerated concrete (AAC). Lightweight aggregate concretes can be used for structural applications, with strengths equivalent to normal weight concrete.
Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight. The highly fluid nature of SCC makes it suitable for placing in difficult conditions and in sections with congested reinforcement. Use of SCC can also help minimize hearing-related damages on the worksite that are induced by vibration of concrete. Another advantage of SCC is that the time required to place large sections is considerably reduced.
Ultra high-strength concrete is defined as concrete with a compresive strength of more the 10, 000 psi.
Early high-strength concrete allows the early curing and hardening of concrete while maintaining the same high strength requirements.
Standard concrete used for roads, bridges and buildings (1500 PSI to 6000 PSI)
Concrete specifically engineered to be water tight commonly used for swimming pools, cistern tanks and roof deck slabs.
