Effect of curing techniques on compressive strength of concrete

This paper presented the findings of an experimental investigation into how common Portland cement concrete develops its compressive strength in a simple setting, such as Lahore, Pakistan. Ten concrete cube specimens of mix 1:1.5:3 was prepared with water-cement ratio of 0.5 for each of the four curing techniques (air curing, water-submerged curing, polythene curing, curing by boiling) until testing ages of 3, 7, 14, 21 and 28 days when their compressive strengths were determined. The findings demonstrated that concrete specimens produced using the water-submergence technique of curing had the maximum 28-day compressive strength of 41.42MPa. The findings indicate avoiding boiling as a curing process and restricting the use of other curing techniques to a 28-day timeframe. It was determined that there is a positive link between concrete specimen curing, curing duration, and compressive strength. This study also offers details on the significance of curing and numerous different methods for carrying out the procedure on the spot.
