Influence of different compacting methods on concrete compressive strength

ABSTRACT Adequate compacting is an important stage contributing for the durability and final quality of concrete structures. The two main ways of compacting concrete are: manual and mechanical (immersion vibrator). This paper has the goal of verifying the influence of those two compacting methods on the compressive strength of concrete from long term data. In order to do that, cylindrical test specimens of a same concrete were molded with different compacting methods and the compressive strength was investigated at 1, 3 , 7, 14, 21, 28, 63, 91, 180, 365 and 730 days. Concrete used was casted i...
