not geting mim 7 days strength that is 67 percent for M-35
and my mix design is perfect there is no doughty,and my
results are near to 7days percentage but not 67 percent.
Answer Posted / v.purushotham
The fallowing check points to be done:
 In between interval you should check the mix ratio
i.e. volume/ weight of material,
 Check cement ratio,
 Check slump while pouring the concrete,
 Check the proper mixing of concrete,
 Check the procedure of filling and compacting of
cube mould,
 Check the bulkage of sand,
 Check the gradation of material every 15/ 30 days
interval and compare the designed materials properties,
 Last but not least check the proper curing of
concrete cubes.

Design a cantilever type retaining wall to retain sand for 4m above the ground. The sand fall slopes at the rate of 1 vertical to 2 horizontal. The weight of sand is 18000 N/m3, the angle of repose being 30. The safe bearing capacity of the soil is 200 kn/m2 at 1/25m below the ground level. Use m 15 concrete mix.

5. Two long boundary walls run parallel to each other at a center to center distance of 1 meter apart. The width and height of the first wall are 0.30 m and 2.5m respectively. While those of the second are respectively 0.18m and 3.5m. Plot the distribution of vertical stress intensity due to walls on a horizontal plane, 1m below ground level. The walls have negligible depth of foundation and are made of brick masonry (y = 19.2 kN/m cu)
