Transcribed Image Text: A trial mix is required for a concrete slab being constructed that is exposed to freezing and thawing as well as deicing agents. The trial mix design strength is 32 MPa (including
overdesign) with a 75 mm slump. For the sand; FM = 2.60 and its absorption is 1.6%. The coarse aggregate has a nominal size of 25 mm with an absorption of 2.1% and a dry rodded
density of 1560 kg/m³. Determine the mix design amounts for the concrete if the coarse aggregate contains 4% water. (keep all calculations and answers to one decimal place except
where indicated. That is, round to one decimal place)
Design Water =
kg/m3
Water to Cement (W/CM) ratio =
(two decimal places)
Cement Content =
