Self-Compacting Concrete is a highly fluid concrete that moves under its weight to spread into place. With no need for vibration or other types of finishing labour, this type of concrete easily pours past congested reinforcement and rebar as a result of super plasticizers, all the while still upholding standard durability requirements and strength characteristics as traditional concrete designs.
Lightweight Concrete is for specific applications. Regular performance based concrete conforms to the structural requirements for building foundations, floor slabs, beams and most building applications.
