Q 1 - Following are the approximate quantities required for 1 m3 of concrete. Check the volumes and adjust, if required, to produce 1 m3.
Cement 330 kg
Water 195 kg
Fine aggregate 730 kgRD 2.68
Coarse Aggregate1250 kgRD 2.64
Air 3.5 %
Q 2 – A concrete plant uses the following quantities of materials per cubic metre of concrete,
Cement 310 kg
Water 180 kg
Fine aggregate 750 kg
Coarse Aggregate1080 kg
The concrete is mixed in batches of 3.5 m3. Find the mass of each material required per batch if the fine aggregate contains 4.0 % excess water.
What will the W / C ratio be ?
