More DetailsThere are different concrete grades for example C15, C20, C25. The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C15 means that the concrete will have a compresion resistance (withstanding a compression) of 15 N/mm2 per square millimetre in 28 days.
More DetailsA C25 mix has a low to medium cement content inclusion, meaning that the strength of the mix is in the middle class of the design concrete products that we offer. This would be used when strength is not the main factor of your concrete application.
