Settlement
is the change in elevation of the surface of the ground caused by deflection of the soil below the slab under load.

Shear Stress
It is very important to know the magnitude of the shear stresses that a concrete slab is subject to, as failure due to shear is often very sudden and catastrophic.
Read MoreShear Stud
A shear stud is typically a small element welded to a steel construction component designed to resist shear loadings between the concrete and steel interfaces.
Read MoreShore Hardness Scale
The Shore Hardness Scale represents the amount of pressure an object or material can endure and the hardness can be defined as the materials resistance to permanent indentation.
Read MoreShot Blasting
can be used to strip, clean and mechanically prepare a concrete surface ready to receive a new covering or to retexture a concrete surface to improve skid resistance.
Read MoreShrinkage
When concrete dries it shrinks due to the reaction of the cement and water forming a product which is of a smaller volume than its component parts.
Read MoreSilica Fume (SF)
can be added to a cement mixture to create very high strength concretes.
Read MoreSlab
A concrete slab is a structural feature, usually of constant thickness.
Read MoreSlip Membrane
To reduce friction below the slab from the sub base it is typical to construct industrial floor slabs upon a layer of 300 micron plastic membrane.
Read MoreSlip Resistance
The ability of a floor surface to resist pedestrian slippage.
