PRODUCT INFORMATION MASONRY BRICK & BLOCK
WHY SPECIFY LITEC®:
• Lightweight - up to 30% lighter than traditional concrete masonry & up to 20% lighter than masonry
• Utilising scoria aggregates
• Offers superior acoustic & fire performance - numerous acoustic tests have been undertaken by the
• CSIRO on both plasterboard & render systems
• Provides increased productivity on site
• Maximisation of floor space - lightweight product means reduced loading on slabs, which translates into
• a more economical slab design
• Cost effective construction - less construction time = improved efficiences.
WHY SPECIFY DENSE WEIGHT:
• Higher compressive strengths suitable for load bearing applications.
FEATURES & BENEFITS:
• Ideal key for plaster, cement & acrylic render coating
• Ideal for bagging & painting
• Solid concrete is a proven insulator
• Impressive fire & acoustic resistance.
TECHNICAL INFORMATION
LITEC®
Litec® is up to 30% lighter than conventional dense weight masonry & up to 20% lighter than masonry
utilising scoria aggregates.
STANDARDS
All C&M concrete blockwork is manufactured to AS/NZS4455 - Masonry Units & Segmental Pavers are tested
to AS/NZS4456 - Masonry Units & Segmental Pavers/: Methods of Test.
FIRE RESISTANCE
AS3700 - Masonry Structures sets out the method for determining fire resistance of walls based on test data.
It is recommended that designers calculate or check the structural adequacy, integrity & insulation for each
wall configuration to ensure conformance to the Building Code of Australia (BCA). C&M have an extensive
range of bricks & blocks meeting the requirements of the BCA. Refer to the C&M Fire & Sound brochure for
more information.
ACOUSTICS
The statutory requirements for sound attenuation are set out in Section F5 of the BCA. The new BCA
deemed-to-satisfy provisions increase the levels of airborne sound insulation & apply to wall/floor systems
tested in the laboratory. These figures are Rw + Ctr not less than 50. C&M have a number of high performance
wall systems which have been developed to accommodate the new stringent requirements imposed by the BCA,
to satisfy all acoustic needs. Refer to the C&M Fire & Sound brochure for more information.
CONTROL JOINTS
Control Joints must be incorporated in masonry as necessary to control & limit the movements referred to in
AS3700 clause 2.5.2.2. Control joints should extend the full height of the wall & be spaced 8m centre for
concrete units & at 6m centre for light weight units where walls are not interrupted by full height doorways or
window openings.
GENERAL GUIDELINES
All concrete blockwork should be laid dry, so covering on site is recommended. Whenever work is stopped, the
top of walls should be covered to prevent moisture entering the cores of the blocks and/or cavity. All mortar joints
should be allowed to set to "thumb print" hardness before tooling. Brush away excess mortar with a semi stiff
brush at the end of each days work.
CLEANING
Care should be taken to keep bricks & blocks as clean as possible during laying. There are various methods of
general cleaning from dry brushing, water washing as well as using chemicals. For a complete listing refer to the
CMAA Code MA42. When using a weak acid mixture it is recommended for cleaning down at no stronger than
1 part acid to 20 parts water. Walls should be wet thoroughly before application & washed thoroughly with water
after application. High water pressure is not recommended. Note: Always trial solution in a small area which is not
highly visible.
STRENGTH
For load bearing projects bricks are manufactured to be greater than 15MPa. Higher strength grades are available
to order.
NOTE
In Victoria, 80% of bricks have a frog & 20% are solid. Frogs should be laid upwards.
CLAIMS
All products must be inspected prior to installation to ensure satisfaction of colour & texture. No claims will be
accepted once product has been installed.
