300mm Series Alphalite Series Plain Grey Blocks by Austral Masonry

Lighter and Easier to Install

Alphalite blocks are lighter than conventional grey blocks which makes them easier to work with on site and install.

Many aggregates used in the Alphalite mix are by-product materials which means they require less quarrying of natural sands or stones.

Low Embodied Energy

Alphalite is kiln-cured, but unlike clay units, the heat is low for concrete masonry, with some steam added for even curing. Because Alphalite masonry units are considerably lighter than standard concrete masonry this reduces emissions associated with product transport.


Many masonry buildings have passed their 100 year anniversaries.
Structures that last longest, require less maintenance, and can be adapted forreuse having a lesser impact on the environment.

Better Product Lifecycle

Alphalite is low-pressure cured with minimal steam required.
This low embodied energy combines with higher durability to make
a favourable lifecycle analysis; at the close of which,
Alphalite masonry can be crushed and re-used.

Have you seen the 150 Series Plain Grey Blocks Available 



The Alphalite mix was designed with the intention of using as
much by-product material as possible. No beaches or river beds are disturbed and cement usage is minimised.

Austral Masonry manufactures a range of masonry bricks and blocks complying with the requirements of the Australian Standard
AS/NZS4455.1:2008 tested under AS4456:2013.

The Alphalite range has been designed as all-purpose units
to meet all your masonry site requirements. These masonry units are not only lightweight and loadbearing but also achieve high fire rating and sound
as well as having many other attributes.

Alphalite gives you:

  • Fire rated and sound rated masonry 
  • High slenderness ratio
  • Structural lightweight masonry (15MPa) 
  • Ease of rendering 
  • Easier to cut than standard blocks

Alphalite units are designed to be painted or rendered as there can be significant colour variation from batch to batch. For face block applications Austral Masonry recommends the GB Masonry Collection of colour masonry products. 

Features and Benefits 

Due to their mass, concrete masonry blocks out noise better than traditional building materials. resulting in a quieter home environment.
When you build with concrete masonry products you are building with a material that requires minimal maintenance and upkeep so you have more time for the important things in life.
Concrete masonry products are high thermal mass products which slow the transfer of temperature fluctuations from the outside into internal living areas. This reduces the need for use of artim’al heating and cooling devices and thereby reduces associated energy costs.
Concrete masonry products are available in a range of over 78 colour and finish combinations. This offers you a wide range of products to choose from to suit the style of your home
Concrete masonry products are made from non combustible materials so they are fire resistant and therefore ideal for bushfire prone areas.
Masonry product production has minimal impact on the environment because they do not deplete precious natural and limited resources like many other materials. Concrete masonry products are cured in temperature controlled kilns with comparatively little energy used compared to kiln fired products.
Due to their mass, concrete masonry products slow the transfer of external temperature fluctuations into internal living areas there by reducing the need for artificial heating and cooling devices.
Exterior Walls that will hold up to heavy storms, U.V. degradation, blistering heat, and sub-zero temperatures.
Because masonry products are made from concrete they are strong and durable which means that they can endure significant impact from external forces with minimal if any impact
When comparing other products on the market concrete masonry is an affordable option. This is especially true when considering the complete building system as concrete masonry can reduce or negate the need for accessory products such as sarking and insulation.
Masonry walls won’t be degraded by termites as there’s no wood for the termites to eat.
Concrete masonry products are much faster to build with than some commonly used walling materials and have the added benefit of being both structural and aesthetic.
