Concrete

Strong composite building material made from the combination of aggregate and cement binder.

This page lists aggregate suppliers and concrete block manufacturers for use in a wide range of building projects.

Concrete is a durable and long-lasting material, regularly reinforced with steel bars or ‘rebars’. Prestressed concrete is reinforced with prestressing tendons of tensioned steel rod or cable to increase its tensile strength. Precast concrete, e.g. concrete blocks and masonry units are moulded and cured offsite, then transported to the project.

Concrete admixtures and additives help overcome common pitfalls in the material. Chemical cement admixtures improve water resistance, appearance, or durability. Concrete accelerators or retarders speed up or slow hardening, whilst concrete plasticisers improve workability. Mineral admixtures such as fly ash, lime or silica fume may also improve quality. Recycled materials used in aggregate help improve the green credentials of the material.

Suppliers and manufacturers of cement, cement admixtures, concrete blocks and aggregate can all be found here.
