Concrete that very likely would pass inspection

Jun 20, 2014That would mean all-in ballast would be acceptable for C20 or C25 cement. It seems. Your main issue is control over the critical things. It is easy to get the cement to all-in ballast ratio correct (1:6 for C20, 1:4.5 for C25). It is less easy (I presume) to get the cement to water ratio correct. The concrete though should be a dry mix. Get price
