Just Foamed Concrete

2019-5-21 · Initial tests indicate that foamed concrete with a casting density of 1 500 kg/m3 can be less permeable than normal 25 MPa concrete, and accelerated corrosion tests indicate that foamed concrete can be just as durable than normal concrete. These tests still need to be correlated with full scale, long term durability tests.

Foam Concrete For Voidfill & Stabilisation

The fluid nature of Porofoam allows the concrete to free flow into even the smallest of spaces making it highly suitable for voidfill applications. Porofoam can be pumped by either a conventional concrete pump or rotor stator pump. The material typically remains fluid for 2/3 hours after mixing with the foam (dependent upon ambient conditions).
