INVESTIGATION OF COMPRESSIVE STRENGTH OF
2020-6-1 Concrete mixes were evaluated for compressive strength of concrete at the age of 7days and 28days.The result showed a increase in compressive strength of concrete when silica fume is 10% and when M-Sand percentage is 25%. It also shows that further addition of M-Sand resulted in decrease in compressive strength of concrete.

EFFECT OF REBAR ON COMPRESSIVE STRENGTH OF
2009-11-11 The best and most accurate method to determine compressive strength of existing concrete is coring. Rebars always make difficulty in coring of reinforced concrete structures. Sometimes it is not possible to core from plain concrete areas. There are serious considerations for effects of rebar on compressive strength of concrete cores in some countries.
