Properties of self compacting concrete at different curing condition and their comparison with properties of normal concrete

الملخص EN

The experimental investigation carried out is to study the effect of curing methods on the compressive, splitting, and flexural strengths (modulus of rupture) of self compacting concrete in comparison to those of normal concrete.

T h e self compacting concrete consisted of Portland cement (P.C) limestone powder (L.S) (L.S 8 % / 92 % P.C), sand, gravel and super-plasticizer.

The specimens were cured in the air and water, for the period of 7, 14, and 28 days.

Three specimens were tested for each point of each property.

The results showed that the water cured specimens gave highest compressive strength, splitting tensile strength and flexural strength than specimens cured by air about 11 %, 10 % and 11 % for self compacting concrete at 28 days respectively.

The results also show that self compacting concrete gave high early strength i.e.

strength before 28-days.

T he failed specimens indicated that there was no segregation and a good bond between aggregate and matrix.
