Compression test on concreteCivil Engineering Portal

The concrete cube test result will be satisfactory but the concrete in the structure would have a much lower strength. 3.8.CONCRETE COMPACTION Concrete ingredients when mixed have considerable amount of entrapped air depending on the workability. High workable mixes have lesser entrapped air than low workable mixes.

Wet and dry cured compressive strength of concrete

 · However compressive strength of GGBFS is found to be satisfactory when compared to control NPC concrete for 80 replacement ratio. Table 4 also shows that for dry curing conditions compressive strength of GGBFS concrete is found to be equivalent to that of control NPC concrete for 20 and 40 replacement ratio at 28 days and three months.

Chapter 5Testing of Fresh and Hardened Concrete

 · It has been found that an adequate air-void system can be difficult to achieve in EOT concrete even when the air content of the fresh concrete was satisfactory. Thus if durability problems have been observed in EOT concrete repairs an agency should consider measur- ing the air-void system parameters of the concrete.

After the third tamping the excess concrete shall be struck off flush to the top of the cone. Lift the mould carefully upwards to minimise disturbance of the concrete inside.

Efflorescence on ConcreteCauses Prevention and Removal

In wet conditions such as rainy season the surplus water acts as a medium for the salts to transport to the surface of concrete and form crystalline white powder. Variability of concrete (compaction or curing) can result in localised problems where water can permeate more easily through the concrete.
