Admixture Dosage ??

Admixture Dosage ??

Hi there,

We have a different mixes with cement varying from 400 to 480 Kgs/ cum. The W/C is kept constant = 0.35 for all the mixes. The mixes are like this

Cement W/C     %Dosage

400    0.35     0.5%
420    0.35     ??
440    0.35     ??
460    0.35     ??
480    0.35     ??

Now, the first mix was trial batched and slump was found acceptable @ 60 mins with a dosage of 0.5% of admixture by v/w of cement.

Can you please let us know for the remaining trials for a given slump wheather the dosage of admixture will increase, decrease or remain the same???

With Regards,
