Compare ! Quazite ® Precast Concrete Strength Compressive: 9000 to 11000 PSI Tensile: 600 to 700 PSI Flexural: 800 to 1700 PSI Compressive: 2000 to 4000 PSI Tensile: 200 to 400 PSI Flexural: 400 to 800 PSI Weight and Geometry Polymer material superior strength-to-weight ratio allows thinner walls and lower weight - 66% to 90% lower - requires no special lifting equipment; can be adjusted by hand. Porous material requires thick walls to protect rebar - higher weights require boom truck or crane to move and place - cannot be adjusted without auxiliary equipment. Water Absorption Exceptionally resistant to moisture absorption, less than 1% per ASTM D-570. Absorbs moisture . up to 9% per ASTM C-478. Chemical Resistance High resistance to most chemicals (tested to ASTM-D543). Will deteriorate from inorganic acids, strong alkalines and saltwater. Material and Product Performance Product performance depends on materials and design . QUAZITE® is 250% stronger in compression and much stronger in tension. The design is state-of-the-art; the performance is superior! Weaker material uses thicker walls and shortens lifespans. Spalling Closed cell structure and non-metallic surface reinforcement produce a material that is highly resistant to spalling. Porosity and ferrous reinforcement produce susceptibility to environmental, freeze and impact induced spalling. Skid Resistance Slip resistant profile is cast into the surface. Coefficient of friction over 0.6-ADA compliant for accessible routes. Variable broom surface profile which chips easier. Delivery Area Available through national stocking distributor network for continuity throughout your project. Limited delivery area - increased delivery cost. Cost Reduced installation and maintenance costs result in lower lifecycle costs. Lower unit cost - but higher installation costs due to personnel and equipment.
