Effective Span
Effective Span - The effective span is used to calculate the flexural resistance of an element.
Read MoreEffective Depth (d)
Effective Depth (d) - The effective depth (d) of a reinforced concrete floor slab is the distance from the compression face to the centre of the tensile steel when an element is subjected to a bending moment.
Read MoreEarly Thermal Contraction
Early Thermal Contraction - If the rate of heat generated by cement hydration reduces, there will be net cooling and the concrete will contract.
Read MoreDynamic Load
Dynamic Load - A dynamic load is caused by any load which can vary location and or magnitude over time.
Read MoreDusting
Dusting - is the formation of powder on the upper surface of a concrete floor due to the disintegration of the top layer of material.
Read MoreDrying Shrinkage
Drying Shrinkage - All concrete shrinks as the water in the concrete evaporates to the atmosphere.
Read MoreDry Shake Toppings
Dry Shake Toppings - A dry shake topping is a thin cementitious layer which can be added to the top of a slab following the initial laying of the concrete.
Read MoreDrop Testing
Drop Testing - aka BRE Sceeed Testing - Measures the soundness of a screed floor to help determine whether certain factors make a screed unsatisfactory.
Read MoreDrive-in Racking
Drive-in Racking - There is no division by aisles and therefore high storage density is achieved. Cantilever brackets attached to the racking frames support the pallets. This type of racking can be up to about 12m high.
