Strong, durable and allpurpose.The grey masonry block range has been designed as all-purpose units to meet all your masonry site requirements. These masonry units are not only lightweight and load-bearing, but also achieve high fire and sound ratings.

Grey block 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.

The Benefits–When considering building products to use on your project its important to understand all the pro’s and con’s before. You know you’re making the right choice when you consider the host of benefits they offer.

More affordableFor a premium product, our coloured concrete masonry range offers an affordable option.

Extensive colour rangeConcrete masonry products are available in a vast range of colour and finish combinations.

Low maintenenceMinimal maintenance, maximum impact. You’re guaranteed a long-lasting, tough, and easy to care for solution.

All-weather resistantHeavy storms. Blistering heat. Sub-zero frosts. While they are not waterproof, our products are designed to hold up to virtually anything our weather systems are capable of throwing at it.

Fire-resistantAll of our products are non-combustible and highly fire resistant – making them ideal for bushfire prone areas.

Termite resistantWith no organic wood materials present in our concrete formulations, our masonry range is naturally termite resistant.

Grout for Core FillingThe correct grout specification (mix design) is critical to achieving the structural design of a reinforced wall. The grout used to fill the cores of blockwork walls should be specified as follow:

• Grout to comply wit AS3700 Clause 10.7 Part 11.7.• Characteristic Compressive Strength minimum 20MPa.• Where grout is to provide protection to reinforcement,

cement content shall be not less than 300kg/m³.• Round aggregate (if any) not more than 10mm.• Clean sand (1.2m³)• A pouring consistency which ensures that the cores

are completely filled and the reinforcement completely surrounded without segregation of the constituents.

Control JointsControl Joints are provided in masonry walls in order to prevent cracks appearing. These cracks can be caused by various movements such as:

• Shrinkage of concrete masonry units (or expansion of clay masonry units).

• Temperature movements.• Differential settlement of footings (Figure 17).- Hogging support: top tension cracking and diagonal cracking is likely to occur.

- Sagging or dishing support: friction at the base may stop the tension cracking, diagonal cracking still likely to occur.

In unreinforced 90 mm and 110 mm thick walls (including veneer and cavity construction) control joints should be spaced at all points of weakness, and not more than 6 m apart.

In unreinforced walls of 140 mm and 190 mm thickness the inclusion of horizontal bond beams is recommended. In this case the spacing of control joints may be increased up to a maximum of 8 m. The more vertical cores that are filled with grout and reinforcement the greater will be the control of cracking.

Material Quantities for 1m of Mortar• For every 800 full height blocks (390 long x

190 high) or 64m² of wall, approximately 1m³ of mortar mix is required, allowing for wastage.

• There are 12.5 full blocks per square metre of wall surface area.

Mortex Preblended Mortar1 x 20kg bag will cover 10-12 x 100 and 200 Series Full Height Blocks.

Unreinforced Masonry Construction

Control joints should be built into unreinforced concrete masonry at all joints of potential cracking and at the locations shown on the drawings, but in no case greater than 6-m spacing in articulated residential construction and 8-m spacing in other construction.

Reinforced Masonry Construction

Control joints should be built into reinforced concrete masonry at all points of potential cracking and at the locations shown on the drawings. In reinforced masonry walls over 3 m high, the spacing of control joints should not exceed 16 m. In reinforced masonry walls 3 m or less in height, and incorporating a reinforced bond beam at the top, the control joints may be deleted.

Efflorescence is the formation of salt deposits, usually white, on or near the surface of concrete causing a change in appearance. Apart from the discolouration, efflorescence is generally harmless.

Austral Masonry recommends the use of sealers and AUS-LOC mortar additive to help combat efflorescence.

Sealers are applied to the blocks after installation and help to prevent migration of salts in the concrete mixture from migrating to the surface of the blocks face. Please contact your local Austral Masonry representative for recommended sealers.

AUS-LOC mortar additive is recommended as a water repellent admixture for cement/sand mortar designed specifically for laying water repellent concrete blocks made with the addition of Tech-Dry Block Emulsion.

It may also be used as a water resistant admixture for other cement/sand mixtures such as cement/sand renders or concrete masonry.

Please note The supply of raw materials can vary over time and as a consequence colour and finish variation can occur between product types and production batches. To see indicative samples before placing an order please contact your local Austral Masonry office.

Some of the important features of AUS-LOC include:

• Non-toxic water-based formulation.• Improves workability of cement/sand mortars.• Increased adhesion of cement/sand mortar.• Reduces water penetration, efflorescence

and water-borne staining.• Does not significantly change vapour

permeability of cement/sand mortars.• Easy to use and cost effective.

Mortex Preblended Mortar–Mortex is a factory manufactured, quality assured premixed M4 rated mortar solution. Its consistency can save labour time, increase efficiency, remove the need for on site blending, and it is compliant with AS3700:2018. Mortex takes the guess work out of mortar blending and reduces the potential for under strength, non compliant mortar use.

This can ultimately reduce potential liabilities, saving money and time on rectifications. With the adoption of ISO9001:2008 principles, the mortar constituents are accurately measured and blended in a controlled environment to ensure consistent, homogeneous mortar is produced on-site.

ColoursWhite mortar is currently the most popular colour. This is made by mixing light coloured cement and white sand and results in a traditional brick and mortar look. Mortar can be coloured by adding powdered or liquid pigments to the mortar as it is being mixed by the blocklayer. It can also be tinted to match the brick colour, giving a very even wall colour.

Please confirm with your blocklayer what their mortar colouring offering is before making your final decision.
