Sustainable Blocks - Alphalite QLD

ENVIRONMENTAL RESPONSIBILITY

Materials

As well as being kinder to blocklayers, the new lighter Alphalite blocks are also kinder to the planet and incorporate 40 recycled material in their manufacture.

Alphalite blocks will not suffer from efflorescence and are available in exposure grade making them durable for coastal and post industrialsites.

Emissions

Alphalite is kiln cured, but unlike clay masonry units, the heat is low and largely exothermic,with some steam added for even curing. Alphalite masonry units are 30% lighter than standard concrete masonry. This reduces emissions due to transport.

Durability

The masonry structures code: AS3700:2001, Section 5, defines what areas require higher durability and prescribes AS/NZS4456.10 as the method of test.
When tested to AS/NZS4456.10, Alphalite masonry units achieved the "Exposure Grade" rating which AS3700 requires for masonry in "severe marine environments" (areas within 1km of a surf coast or within 100m of tidal waters).

Summary

The Alphalite mix was designed with the intention of using as much by-product material as possible.
Alphalite is a low pressure cured with minimal steam required. This low embodied energy combines with higher durability to make a favourable life-cycle analysis; at the close of which, Alphalite masonry can be crushed and reused.
