Influence of Plain and Fibrous Concrete Composite on Creep Development: A Review

Abstract

Largely, structures are subjected to static dead loads in building and civil engineering construction. The exposure of concrete structure to sustained load leads to a progressive decrease in its structural strength with time, which may perhaps result to creep deformation. Despite the vast usage of concrete, there still exists a gap in the understanding of the mechanism of creep deformation in cementitious composites due to its complex nature compared to ferrous and synthetic rope materials. This inadequate understanding is more evident in composite materials such as fibrous concrete (FC), especially the bio fibrous concrete. However, it is difficult to determine the quantitative nature of the positive contribution of fibre inclusion in concrete to creep behaviour. The outcome of the review done in this paper submit that the majority of study done and available in literature are on steel fibre, and there is no consensus on volume of fibre content put forward as the optimum. The study assessed the influence of plain and fibrous concrete composite on creep development. This was done through examining available literature recounting the previous and current development of creep deformation and situating it in the context of plain and fibrous concrete in order to be able to bring to the fore appropriate issues on recent advancement in compressive, tensile and flexural creep of concrete. It was discovered that though creep has been an age long phenomenon in concrete technology. The extent of the understanding of creep of FC by concrete scientist and researchers was limited resulting in the lacuna of available literature of creep of FC experienced now. It becomes imperative for all concrete scientist and researchers to give greater attention to understanding the influence of fibre on creep of concrete so that the mechanism of creep deformation in cementitious composites could be well understood.
