“…Furthermore, a specific test was carried out to determine the initial description of the core temperature of the concrete and the mix design in this study for the casting of the 5 per cent based on previous experimental [15] and 15 per cent variation of fly ash preplaced method as comparison specimens, then cylinder conventional method with a mixed design based on SNI 03 2834 2000 [16] as conventional concrete. The cylinder size for the three test objects is 150 x 300 mm, with temperature monitoring starting from the completion of casting with technical checks for the first 24 hours every 2 hours.…”

Fly ash is known as a waste from burning coal which has answered the issue of global warming to be an alternative constituent material for concrete. Casting on mass concrete has a major problem like the thermal cracking caused by the hydration process in the cement chemical component. The prevention solution is using fly ash for a mixed design. Moreover, the casting method using the preplacedd aggregate method could be able to control the heat of hydration which lowers the temperature of the concrete by minimalizing the friction between the coarse aggregate particles during the mixing operation. This study aims to analyze the behaviour of surface and core temperatures in mass concrete using the preplacedd aggregate concrete method and substituting part of the cement with fly ash. The result from the study showed that the temperature behaviour of preplacedd aggregate concrete for mass concrete decreased and slowed the temperature rise if compared to the conventional methods. Moreover, the partial substitution of class C fly ash in the concrete mixture leads to reduce the temperature of the mass concrete.

“…The scienti c literature in the eld of concrete mechanics and technology indicates numerous publications on triaxial compression testing of concrete and the analysis of TSC properties. A critical factor affecting the nal properties of TSC is the selection of grout proportion [51]. With an increase in the water/binder (W/B) ratio and the sand/binder (S/B) ratio in the grout, there is a decrease in compressive strength, tensile strength, and modulus of elasticity of TSC.…”

This study conducts a comprehensive comparative analysis of the triaxial compressive strength and associated mechanical properties between Two-Stage Concrete (TSC) and Conventional Concrete (CC). Through rigorous using triaxial test methodologies, our research quantitatively delineates TSC's mechanical superiority, promoting its broader application in diverse construction settings. Key findings reveal that TSC, particularly types with finer aggregates, demonstrates superior shear strength, achieving up to 52.4 MPa under dry conditions compared to CC's 48.38 MPa. Furthermore, TSC exhibits remarkable stress tolerance, withstanding up to 82.04 MPa, significantly outperforming CC, which manages only 69.61 MPa under similar conditions. TSC also maintains higher modulus of elasticity and internal friction angles, indicating better deformation behavior and shear resistance. Additionally, TSC shows greater resilience to moisture, suggesting its potential for use in variable moisture environments. These properties highlight TSC’s robustness for high-load applications and its suitability for infrastructure prone to environmental fluctuations. By aligning with existing literature on the benefits of finer aggregate sizes in enhancing concrete's mechanical resistance, this research underscores the strategic advantage of integrating TSC in modern construction practices, emphasizing its enhanced strength, durability, and environmental adaptability.
