and my mix design is perfect there is no doughty,and my
results are near to 7days percentage but not 67 percent.

Answer / sjtbehera
what you sure about your mixing. you check slump test, you
check bulkage of sand, you check waste of cement while
mixing, you check compaction factor, if this is right then
result is not obtained please contact Indian standard Buero.

Answer / bhauso mane
there are many reasons of concrete failure result as bellow
1)water to cement ratio - increasing water cement ratio
decreases the strength of concrete.
2)quality of cement- firstely check the quality of cement .
3)raw material properties like silt in sand,flaky,
elogation,& hardness of aggregate.
4)mixing & sampling of concrete.
5)compaction & curing of cubes.
6)test machine accuracy.

Answer / 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.
