Assessment of aggregate mixture reactivity in concrete at 60°C

Data set presented in publication 'Assessment of aggregate mixture reactivity in concrete at 60°C' Structure and Environment 2024, vol. 16, (3), pp. 153-157'Data_set_expansion': Length changes measurements (expansion) of concrete beams in Miniature Concrete Prism Test (AASHTO T 380). Tests were performed on 6 aggregate mixtures (SB, SW, ST, AB, AX, AW) stored in molar sodium hydroxide solution at 60°C for 84 days. Measurements were performed on dilatometer design in IPPT PAN (patent WUP 08/2022). Measurements were made on 3 samples, the length change was calculated in acc. to AASHTO T 380. The expansion results (mean value of the length change) are presented in Fig. 1 in the above publication.‘Data_set_compressive_strength': Compressive strength measurements on 50 mm cubic samples cut from the concrete beams. The samples stored in 1 molar sodium hydroxide solution (1 M NaOH) at 60°C and water at 20°C for 84 days. Compressive strength was performed on at least 3 samples (with load rate 2400 N/s) using concrete compression machine Controls AUTOMAX MULTITEST.‘Data_set_modulus’: The resonant modulus of elasticity of the concrete was measured with the impulse excitation technique using a GrindoSonic MK5 device with a piezoelectric detector on the concrete beams stored in 1 molar sodium hydroxide solution (1 M NaOH) at 60°C and water at 20°C for 84 days. Presented data contains mean values for a concrete beam calculated in software WINEMOD - Version 2.05.
