Effect of Cured Time on Creep of Lightweight Aggregate Concrete

Abstract

Creep and shrinkage are such properties that will occur in concrete when they are under load and exposed to surrounding. Since this property will cause deformation which may decrease the design strength of the concrete, it is necessary to do have more knowledge on this phenomenon. So, we will study the effect of creep on 7 and 14 days of cured time of specimens which sealed or unsealed will be considered, respectively. The specimens have shown how the concrete strains when they are under sustained load with time. Besides, the sealed specimens have shown how the basic creep is different from the total creep of concrete. Further, the specimens of loading at different ages have shown how the age at application of load influences creep. The result of the experiment has shown the relationship of strain under sustained load and time. Moreover, it is shown that creep is mainly related to the strength developed in the concrete.
