A single aggregate mix design was developed based on a slag/Portland binder blend and crusher sand. The primary design criterion, after performance, was the fluidity of the shotcrete and ... The design of a single aggregate concrete on Cullinan Diamond Mine T r a n s a c t i o n P a p e r

Maximum size of coarse aggregate: Maximum size of aggregate affects the workability and strength of concrete. It also influences the water demand for getting a certain workability and fine aggregate content required for achieving a cohesive mix. For a given weight, higher the maximum size of ...

Concrete mix design is the method of correct proportioning of ingredients of concrete, in order to optimize the above properties of concrete as per site requirements. The site engineer should give following information while giving material for mix design to the mix design laboratory: –
