Effects of Portland cement addition on Young’s modulus of geopolymer concrete cured at ambient conditions
Journal Title: Bulletin of the Military University of Technology - Year 2018, Vol 67, Issue 4
Abstract
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. Keywords: engineering, construction materials, geopolymer concrete, Young’s modulus, Poisson’s ratio, alkali-activated concrete<br/><br/>
