A fun bit of Scuttlebutt regarding Boral. I work for a construction company, and we are building an office block for an existing client. The clients wanted to build the project "environmentally friendly". They proposed using Boral's "Envirocrete" environmentally friendly concrete product. After the first pour, we did our usual concrete testing and the desired (advertised) MPA strength wasn't achieved. Assured this was just a bad batch, the concrete was replaced and it failed again! Cost the client a fortune. Needless to say we arent using this product anymore.
