Flowing Concrete

Grange Supa Flow 10
Multi purpose flowing 10mm mix ideal for flowing foundations and locations and higher specification where access is difficult

Grange Supa Flow 20
Multi purpose flowing 10mm mix ideal for flowing foundations and locations and higher specification where access is difficult

Grange Supa Flow SCC
Fully self compacting version of the Supaflow 10, achieves compaction into every part of the mould or formwork simply by means of its own weight without any segregation of the coarse aggregate

Grange Cemfloor SCC
Fully self compacting version of the Supaflow 10, achieves compaction into every part of the mould or formwork simply by means of its own weight without any segregation of the coarse aggregate. This form of SCC has a higher tensile strength enabling its use in re-inforced foundations without the need for steel re-inforcement

Screeds

Grange Cemfloor
Cement based screed supplied in liquid form via truck mixer, commonly used as a solution in underfloor heating applications, set levels and pour into place with minimal working required, very low shrinkage, walk on it the next day, Cemfloor Screeds can be trafficked earlier and used in environments where water is present

Fibre Concrete

Various types of fibre may be added to the concrete to improve its properties. The main fibres used are steel, polypropylene and macro synthetic

Steel fibre concrete is used extensively for industrial ground-supported floors. The fibres provide some degree of control over the formation of early thermal and shrinkage cracks. They give the hardened concrete some post-cracking residual strength.

Various types of short polypropylene fibre may be added to concrete. The fibres are used to reduce the risk of crack formation in young concrete (plastic cracking). They do not significantly affect the properties of the hardened concrete and can be used to provide freeze thaw and impact resistance

Larger diameter synthetic fibres known as macro synthetic fibres can give similar post-cracking strength to steel fibres. They are used in similar applications, particularly when there are concerns about durability.

A recent innovation has been the use of steel or macro synthetic fibres to replace the nominal reinforcement in composite slabs on metal decking (Structural elements/Suspended floors/Steel concrete composite suspended floors).

Grange has extensive experience of the use of all fibre types in concrete, if you have any queries on the use of fibres please feel free to ask us and we will be able to help.
