Understanding the Long-Term Development of Portland Pozzolan Cement Concrete Post 28 Days
This study examines the age-dependent development of compressive strength in Portland pozzolan cement (PPC) concrete under both curing and non-curing conditions. Four beam specimens, each measuring 500 mm × 200 mm × 350 mm, were prepared with varying compressive strengths. Testing was conducted at 2...

| Summary: | This study examines the age-dependent development of compressive strength in Portland pozzolan cement (PPC) concrete under both curing and non-curing conditions. Four beam specimens, each measuring 500 mm × 200 mm × 350 mm, were prepared with varying compressive strengths. Testing was conducted at 28, 60, 90, and 180 days using the rebound hammer test and Windsor Pin Test. The results indicate the tool’s reliability in predicting gradual increases in strength over time. However, this correlation suggests that the factors influencing compressive strength, such as moisture, concrete age, surface smoothness, and environmental exposure, play crucial roles in affecting rebound readings and surface hardness. |
