EK400
For heavily-loaded columns or those carrying large moments resulting in high compressive forces the bedding should be fine concrete using a maximum aggregate of 10 mm size and a water-cement […]
EK320
Concrete compressive strength increases with a higher cement content and a lower water-cement ratio.
EK259
Creep increases with an increase in the water-cement ratio.
EK235
A water-cement ratio of 0,5-0,7 may produce a concrete strength of about 35 MPa and 20 MPa respectively.
EK234
A water-cement ratio of 0,25-0,35 may produce a concrete strength of about 40 MPa.
EK233
A water-cement ratio of about 0,35 or higher is needed for the concrete to be reasonably workable without additives.
EK232
For complete hydration of a given amount of cement, a water-cement ratio (by weight) equal to 0,25 is needed.
