Sep 03, 2019· The reason you can't find aprescribed mix ratioforC40is it doesn't exist. BS5328 only goes up to 25N and anything above 20N can't bemixedwith all in ballast. That's not to say you couldn't end up with amixhigher than 25N - just that it's not predictable based on themix ratio. The only way to guarantee 40N is readymix.

Mar 19, 2019· Workability: Theconcrete mixworkability is the property that determines themixcapacity to be placed and consolidate properly, allowing to finish a product without segregation. Consistency: This property determines the mobility and slump of theconcrete mix. This characteristic is measured in terms of slump, the higher slump values, the more manageable, and greater mobility will be obtained.

By Adam D. Neuwald. Two of the most commonly specified requirements forconcreteused in the manufacturedconcreteproducts industry are thedesigncompressive strength (f’ c) and the maximum water-to-cementratio (w/c).These two values are inversely related, which means that as the water-to-cementratio increases, the compressive strength decreases.
