This paper presents the results of Young’s modulus and Poisson’s ratio tests conducted on samples made of low-calcium fly ash-based geopolymer concrete samples and on samples with a 10% addition of Portland cement, cured at ambient conditions. Furthermore, the measurement system, as well as sampling and sample preparation methodology, are discussed. Strain was tested concurrently using resistive strain gauges and extensometer on cylinder-shaped samples with a diameter of 150 mm and height of 300 mm.

W artykule przedstawiono wyniki badań modułu Younga oraz współczynnika Poissona przeprowadzonych na próbkach wykonanych z betonu geopolimerowego na bazie popiołu lotnego niskowapiennego oraz próbkach z 10% dodatkiem cementu portlandzkiego dojrzewających w warunkach laboratoryjnych. Ponadto przedstawiono układ pomiarowy oraz metodologię wykonywania i badania próbek. Odkształcenia badano równocześnie przy użyciu tensometrów rezystancyjnych oraz ekstensometrów na próbkach walcowych o średnicy 150 mm i wysokości 300 mm.
