Hi
Just had some ready mix concrete put in place.
The job ticket listed the following info :
3.25 cubic metres of foundation concrete ( Grade ST2 S3 ).
926 kgs of cement
3033 kgs of sand
3723 kgs of stone
337 kgs of water
Can anyone tell me how to determine what ratio this is ?
I have read that ST2 is C20N which is 4:2:1 ?
What does the S3 part mean - is this the slump by any chance ?
Cheers.
