INTERNAL CURING EFFECT ON PROPERTIES OF SELF-

internal curing on the mechanical properties of self-compacting concrete, shrinkage strain, permeability and corrosion of rebar has been evaluated. According to the obtained results, the internal curing of self-compacting concrete containing lightweight aggregates reduced or even eliminated the shrinkage strain.

2015-8-30  In this study, we used internal curing to improve various properties of concrete containing RCA. Recycled fine aggregates with saturation degrees of 0%, 50% and 100% were studied to investigate the effect of saturation on the concrete’s compressive and split tensile strength and on its freeze–thaw cycle resistance and shrinkage. 2.

[PDF] Properties of Self-Curing Concrete Containing Palm ...

Nowadays, concrete is widely used in construction due to its good compressive strength. A good concrete can be produced under a proper curing process. Desired concrete strength will only be achieved when it is cured properly. This study highlights the effect of Palm Oil Clinker (POC) and sawdust as internal reservoirs inside concrete for internal curing process of cement.

2000-5-1  Results show that mechanical properties of concrete containing limestone blended cement are less affected by the cessation of moist curing at early ages. This is attributed to the hydration acceleration owing to limestone presence and the increase of fineness in the clinker fraction of the blended cement.
