What Does C20/25 Concrete Mean?
They are C20 and C25 respectively. To understand what C20/25 concrete is, we just need to understand what the "C" & the following numbers mean. Essentially, "C" stands for Concrete. In this case, the 20 stands for a measurement (Newtons) that this concrete can withstand after 28 days. So C20 concrete refers to concrete that can ...
