This datasheet provides guidance on the
preparation of specifications for the supply of premixed concrete.

With the many different designers’ specifications
and suppliers’ proprietary products, it is important
that customers are very specific as to their
requirements when ordering concrete.

Plastic settlement cracks are so-called because
they form while the concrete is still plastic, ie has not set.

This datasheet sets out procedures for removing
mortar smears, splatters or stains from surfaces
such as clay masonry, concrete masonry, concrete,
timber, plasterboard, aluminium and powdercoated
finishes.

This datasheet sets out items in the plans and
specification that the builder should review prior to
ordering materials and commencing construction
of any masonry.

Roadbases are quarry materials which are used in
the construction of road pavements. They are made
up of a combination of coarse and fine crushed
materials which, when placed and compacted at the
correct moisture, form a rigid layer.

Concrete is one of the most widely used
construction materials. Anyone who uses concrete or is responsible for managing or supervising its use should be aware that it may be a hazard.

Thermal mass is why buildings
having solid construction typically
feel cooler during the summer and
warmer during the winter.

This datasheet sets out how to choose the
appropriate 'salt-attack resistance' grade of
masonry unit and mortar type for a project.
|
Jan 1, 2012 –
This data sheet sets out information on the
selection of render types, construction procedures and surface finishes using renders.
|

Honeycombing refers to voids in concrete caused by the mortar not filling the spaces between the coarse aggregate particles.
|

The surface area of cement is a measure of cement fineness. In Australia, the surface
area of cement is determined in accordance with AS 2350.8 Fineness Index by Air
Permeability Method, known as Blaine test.

Drying shrinkage has been ineffectively used by some
design engineers as a means of controlling cracking in
slab construction.

Since the early 1980s there has been steady
progress towards increasing the energy efficiency
of building envelopes, with a view to reducing the
consumption of operational heating and cooling
energy, and reducing greenhouse gas emissions.

This datasheet provides suggested clauses
for inclusion in specifications for honed concrete
surfaces. They are written with flatwork in mind,
although other concrete surfaces can be honed.
|
Aug 1, 2010 –
This data sheet provides a description of the
process and suggested specification clauses for
burnished concrete surfaces, primarily for flatwork
applications.

Roadbases consist of granular materials which
when correctly placed and compacted form a stiff
pavement layer used in road construction.
