WebJan 1, 2024 · Compression strength testing was carried out on produced geopolymer concrete specimens to determine their potential capacity. The force is delivered at a 90-degree angle to either side of 150 mm × 150 mm × 150 mm specimens. The results of the compressive test on samples of different ratios of GGBS and fly ash are shown in Fig. 2. WebThe final setting time of the geopolymers increased with the increase in Si/Al ratio and the decrease in Na/Al ratio, while the proportion of geopolymer gels and macro-mechanical strength of geopolymers increased with the increase in both Si/Al and Na/Al molar ratios, within the range of 1.2~1.7 and 0.6~1.0, respectively.

WebDifferent properties of geopolymer paste [13,14], mortar [14], and concrete [15] were experimentally investigated. If the density of concrete is considered, there are two types of geopolymer concrete, normal weight and lightweight, and the latter may be foamed con-crete [16], or others based on lightweight aggregate [17,18].

WebThe density ranges from 2.026 to 2.207 g/cm3. The water absorption was the lowest of 11.7% at 20% iron sludge. While the compressive strength of the geopolymer is as high as 80 MPa at 20% of the iron sludge.
