| Summary, etc. |
In the concrete industry, external curing with the addition of lime is the most<br/>common method to develop concrete properties and prevent calcium carbonate from<br/>leaching out of the concrete. However, external water could not penetrate through the<br/>hardened concrete, leading to premature hydration which is essential to the strength<br/>development of concrete. To maintain satisfactory temperature and moisture condition,<br/>internal curing is an advanced method to provide internal water reservoirs in a concrete<br/>mixture that prolongs cement hydration. The researchers aim to investigate the effects on<br/>the physical and mechanical properties of concrete using lime water-saturated pumice for<br/>internal curing. This study aims to determine the implications of using different<br/>concentrations of lime water for internal curing on the properties of concrete and to<br/>compare it to the conventional method of internal curing using clean water. This study<br/>adapted the ACI 211.1-91 (Standard Practice for Selecting Proportions for Normal,<br/>Heavyweight, and Mass Concrete) to generate three different concrete mix designs and<br/>then manipulated using the Bentz and Snyder Equation to calculate the amount of water<br/>and fine pumice aggregate for internal curing to create five mix designs with varying lime<br/>water concentrations (0%, 20%, 40%, 50%, and 60%). The parameters studied in this<br/>experiment are compressive strength with 162 cylindrical samples (100mm dia. by<br/>200mm) based on ASTM C39-M, split-tensile strength with 162 cylindrical samples<br/>(100mm dia. by 200mm) based on ASTM C496, and flexural strength with 162 prismatic<br/>samples (150mm by 150mm by 500mm) based on ASTM C293 for the mechanical<br/>properties of concrete. In addition, concrete density and workability of the concrete were<br/>also analyzed using the ASTM C138 and ASTM C143, respectively. Concrete samples<br/><br/>vi<br/><br/>were tested on the 7th, 14th, and 28th day using the Universal Testing Machine. The results<br/>showed slight improvement in the unit weight and workability of concrete. However, there<br/>is a significant difference in the mechanical properties of concrete wherein compressive,<br/>split-tensile, and flexural strength of internally cured concrete is higher compared to the<br/>control sample as the age of concrete progresses. The concrete in terms of its compressive<br/>and split tensile strength has similar behavior where strength increases as lime water is<br/>introduced using internal curing reaching its peak strength at 50% limewater concentration<br/>but slightly decreases as it approaches 60% lime water concentration. While the flexural<br/>strength of concrete with lime water internal curing is lower than the normal concrete due<br/>to the addition of fine pumice. However, the compressive strength increases as the<br/>limewater concentration also increases. |
