There are many types of concrete including foam concrete.
Regular concrete is the lay term for concrete that is produced by following the mixing instructions that are commonly published on packets of cement, typically using sand or other common material as the aggregate, and often mixed in improvised containers. High-strength concrete has a compressive strength greater than 40 MPa (5800 psi). Stamped concrete is an architectural concrete that has a superior surface finish. High-performance concrete (HPC) is a relatively new term for concrete that conforms to a set of standards above those of the most common applications, but not limited to strength. Ultra-high-performance concrete is a new type of concrete that is being developed by agencies concerned with infrastructure protection. Micro-reinforced ultra-high-performance concrete is the next generation of UHPC. During the 1980s, Okamura and his Ph.D. student Kazamasa Ozawa at the University of Tokyo developed self-compacting concrete (SCC) which was cohesive, but flowable and took the shape of the formwork without use of any mechanical compaction. Vacuum concrete, made by using steam to produce a vacuum inside a concrete mixing truck to release air bubbles inside the concrete, is being researched. Shotcrete (also known by the trade name Gunite) uses compressed air to shoot concrete onto (or into) a frame or structure. In limecrete, lime concrete or roman concrete the cement is replaced by lime. Pervious concrete, used in permeable paving, contains a network of holes or voids, to allow air or water to move through the concrete Aerated concrete produced by the addition of an air-entraining agent to the concrete (or a lightweight aggregate such as expanded clay aggregate or cork granules and vermiculite) is sometimes called cellular concrete, lightweight aerated concrete, variable density concrete, Foam Concrete and lightweight or ultra-lightweight concrete, not to be confused with aerated autoclaved concrete, which is manufactured off-site using an entirely different method. Cork cement composites have several advantages over standard concrete, such as lower thermal conductivities, lower densities and good energy absorption characteristics. Roller-compacted concrete, sometimes called rollcrete, is a low-cement-content stiff concrete placed using techniques borrowed from earthmoving and paving work.
