2. Solve 5.9 (metric units only)
3. Solve 5.13
4. Solve 5.21 (report MAS and NMAS according to PCC and AC design requirements. Assume
NMAS criteria to 90% passing for PCC.)
5. 5.26 (please change the value 8 to 18 in Table P5.26, Aggregate C, in some older book prints)
6. Solve 5.33
7. Define two concrete mixture performance problems caused by aggregate properties.
8. The following CA stockpiles are provided to use in an AC mixture design. The stockpiles have
different specific gravities. A blend of CA and FA is prepared with each one of these stockpiles.
Calculate void space in between CA and report mass % of blend. You can assume total volume
as 1 m3.
