Trial Mix for CLSM
Trial Mix for CLSM
(OP)
I'm looking for a trial mix design for CLSM; hand batched at a mine site.
Gradation of Fine Aggregate to ASTM C-33 (this can be supplied)
50 lbs Portland Cement
150 lbs Fly Ash
2700 lbs Fine Aggregate as above
290 lbs water
no WRDA, AEA, plasticisers.
Does anyone have a workable trial batch mix that can be compared to this?

Thats about 1.5% cement.
We just had, for an unsurfaced wearing course, a 19 mm minus mix - with 25% between 4.5 mm and 19 mm; 55% between #200 sieve and 4.5 mm and 20% fines (passing #200 sieve). Used 2% cement. Standard Proctor was 2.3g/cc at 8% optimum moisture content. Compressive strength was 6.2 MPa at 3 days.

If you have a copy, there's a table in ACI 229 that gives a variety of mix proportions. Let me know if you don't have it.
