Abstract

Structures that complied with code requirements still fail due to excessive cracking. Shrinkage is primarily responsible for such failures. Concrete shrinkage is of increasing concern when focusing on maintaining durable structures. Shrinkage in concrete can be broadly classified into two different stages, namely early age and later age. At early ages, the concrete is still moist and there are difficulties in measuring the fluid material. These difficulties have hindered comprehensive physical testing of shrinkage in plastic concrete. This project aims in evaluating the plastic shrinkage of different concrete mixes. Over time, the shrinkage induces cracking which can severely decrease concrete life expectancy. Such cracks can be mitigated by inclusion of materials such as synthetic fibers, shrinkage reducing admixtures, expansive agents and superabsorbent polymers. And the corresponding variation of compressive strength of these mixes is also studied.
