Precast concrete has a lot of advantages like constant production throughout the year, but it's carbon footprint is enormous. This is because of a high cement content and highly reactive cements in the concrete. Unfortunately it is not simple to change to less reactive recipes. So, what makes it so hard for precast manufacturers to reduce the cement clinker?
Short answer: Producing concrete is a highly complex process. You might be thinking: “But it’s just mixing sand, cement and water, what’s so complex about that?” Well, it’s not quiet that easy….
When using Sonocrete, the concrete hardens faster. This means faster stripping or a reduction in cement – our desired effects. But these effects have a flip side: The workability of the concrete. Faster hardening concrete could be hard before it reaches the moulds.
