HySSIL, building better buildings for a sustainable world

General Specifications


The current cementitious HySSIL product range has the following key characteristics:

Suitable for both structural or non-structural applications;
Offers customers a precast panel which is approximately 40% to 50% lighter than a conventional concrete panel of similar strength;
Competitive cost, relative to conventional precast wall systems;
Exhibits exceptional thermal insulation offering reductions in whole-of-life building energy costs;
Reduced existing embodied energy, green house gas emissions and embodied water when compared to other residential walling systems;
Acoustic properties comparable to conventional concrete making HySSIL an ideal material for high density residential living;
A smooth robust surface finish;
Superior fire ratings compared to conventional concrete;
Dense external surface ensures long term durability and
Improved “pull-out” strength and lower concrete shrinkage compared to autoclaved, aerated concrete (AAC) products.

 

The general specifications of the cementitious HySSIL product are represented in Table 1:
