Abstract

Concrete is used in the building sector for its outstanding resilience and long life. Concrete is made by combining ingredients like cement, water, fine and coarse aggregate and other elements to meet the unique needs of each project. Certain additives are included in the work to improve performance. It must be having an adequate moisture and curing for not less than 28 days so as optimum hydration can take place resulting in stronger structures. If the curing is not properly done, then the concrete can losses most of its strength and service life as well. Others such as Self-curing concrete which contains Super Absorbent Polymer (SAP) or Polyethylene Glycol (PEG) are used when human errors occur or the site becomes inaccessible for normal curing purposes. This research investigates these additions at varying compositions between 0.1% - 0.4% (by weight of cement) for SAP and 0.5% -2% (by weight of cement) for chemical admixtures in M25 mix design. During this investigation, the strengths of various mix proportions were compared to those of typical concrete mix designs.
