Tolerances for Concrete Surfaces

Posted on 1/07/2018
Tolerances can be defined as the allowable variations from the specified values or performance levels. Setting tolerances also demonstrate that some degree of variation is inherent in all building work.


Delamination of Concrete Industrial Floors

This Data Sheet provides guidance on the planning, design, construction, maintenance and specification aspects that need to be considered to ensure a successful concrete paving project.


Hot Weather Concreting

Posted on 1/10/2017
Most of the problems associated with placing concrete in hot weather conditions relate to the increased rate of cement hydration at higher temperatures and the increased rate of evaporation of moisture from the fresh concrete.


Ordering Premixed Concrete

Posted on 1/09/2017
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.


Specifying Concrete

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


Durable Masonry Specification Checklist

Posted on 1/04/2015
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.


The supply of Moist Roadbase Materials

Posted on 1/04/2015
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.


Removal of Mortar

Posted on 1/04/2015
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.


Plastic Settlement Cracking

Posted on 1/04/2015
Plastic settlement cracks are so-called because they form while the concrete is still plastic, ie has not set.


Render for Small Projects

Posted on 1/04/2015
This data sheet provides guidance on rendering for small projects


Working Safely With Dry Concrete Materials

Posted on 20/11/2014
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.


No-fines Concrete

Posted on 1/01/2014
No-fines concrete is a concrete containing little or no fine aggregate. The coarse aggregate should preferably be a single-size material (nominal maximum sizes 10mm and 20mm being the most common).


Thermal Benefits of Solid Construction

Posted on 1/11/2012
Thermal mass is why buildings having solid construction typically feel cooler during the summer and warmer during the winter.


Mortar Mixes for Masonry

Posted on 1/10/2012
This datasheet sets out how to choose the appropriate 'salt-attack resistance' grade of masonry unit and mortar type for a project.



Posted on 1/01/2012
This data sheet sets out information on the selection of render types, construction procedures and surface finishes using renders.


Mixing Mortar For Masonry

Posted on 1/01/2012
This data sheet provides advice on mixing mortar for masonry projects. For guidance on choosing the appropriate 'salt-attack resistance' grade of masonry unit and mortar type for a project see Concrete Data 'Mortar Mixes for Masonry'.


Specifying Low Drying Shrinkage ≠ Crack Control

Posted on 1/01/2012
Drying shrinkage has been ineffectively used by some design engineers as a means of controlling cracking in slab construction.



Posted on 1/01/2012
Honeycombing refers to voids in concrete caused by the mortar not filling the spaces between the coarse aggregate particles.


Energy Efficiency in Building Regulations and the Use of Concrete in Housing

Posted on 1/06/2011
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.


The Specification of Burnished Concrete Finish

Posted on 1/08/2010
This data sheet provides a description of the process and suggested specification clauses for burnished concrete surfaces, primarily for flatwork applications.


The Specification of Honed or Polished Concrete Finishes

Posted on 1/08/2010
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.


Sealers for Concrete Flatwork

Posted on 1/04/2010
The main function of a sealer is to prevent staining of the surface and to facilitate its cleaning.


Sound Insulation Properties of Concrete Walls and Floors

Posted on 1/03/2009
The sound insulation performance of a wall or floor is a measure of its ability to reduce the amount of sound that is transmitted from one side to the other.


Stabilised and Modified Roadbase Materials

Posted on 1/10/2008
Roadbases consist of granular materials which when correctly placed and compacted form a stiff pavement layer used in road construction.
