Assessment of the Durability of Concrete Obtained from Laboratory Mix Designs Under Different Environmental Conditions

Description
This paper analyzes five concrete mix designs casted into the laboratory, specifically named as R-12, R-12.1, R-13, R-14, and R-15, with the aim of evaluating their durability under different conditions with different types of admixtures including crystalline admixture. The tests were carried out in several phases: initially, strength of concrete was studied (compression and tension), dry mass of the cracked and uncracked specimens was measured after the similar ages, their weekly water absorption was studied, while this has been done for cracked and uncracked specimens for each concrete mix design. Concrete mass after pre-cracking was measured and the resulting cracks were analyzed through the microscopical evaluation. In the next phase, the samples were immersed into the seawater to compare the progression of the cracks or healing with those soaked in tap water. After drying process, some samples were subjected to 5-bar pressure for 72 hours to assess the water penetration under pressure. Finally, a carbonation analysis of the cubes after breaking was performed. This study aims to provide a detailed assessment of the durability and healing capacity of concrete under various loading, environmental conditions, comparing the measurement results through graphs and statistical analyses.
