Project at a Glance
Material Placed: 3 yards³ (2.3 m³)
Material Density: 118 PCF (1890 kg/m³)
Base Slurry Mix Design: 1:1 sand cement, .50 water/cement ratio
Richway created a set of floating stairs for our new building using 3 yards³ (2.3 m³) of 118 PCF (1890 kg/m³) material. Using material nearly 20% lighter meant reduced dead loads and easier handling, while achieving a 3200 psi (220.63 bar) 7-day compressive strength. Because of the small material quantity, the foam was batched into the truck, achieving the required density before pumping the material into the forms.
