Experimental investigation on fresh and hardened geopolymer concrete by considering various mix design parameters
Fly ash and ground granulated blast furnace slag (GGBS) were mixed with each other at different percentages and various solution-to-binder ratios were used to form the geopolymer concrete (GPC). Sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) make up the alkaline solution, which is used to activate aluminosilicates. NaOH of 8M and 10M concentration was used for experimental work. Different solution-to-binder ratios from 0.4 to 0.45 were studied in this research work. Na2SiO3/NaOH ratio is considered lower for experimental work to achieve economical concrete without compromising mechanical properties. Ambient curing and temperature-maintained curing were used in this research work for curing of GPC specimens. The slump cone test and compressive strength test were carried out on the GPC to analyse the results of workability and strength by varying the mix design parameters of GPC. Experimental results show that changes in solution-to-binder ratio, concentration of NaOH, type of curing, proportion of raw material, and properties of raw materials also affect the fresh and hardened properties of GPC.
期刊介绍：
The Asian Journal of Civil Engineering (Building and Housing) welcomes articles and research contributions on topics such as:- Structural analysis and design - Earthquake and structural engineering - New building materials and concrete technology - Sustainable building and energy conservation - Housing and planning - Construction management - Optimal design of structuresPlease note that the journal will not accept papers in the area of hydraulic or geotechnical engineering, traffic/transportation or road making engineering, and on materials relevant to non-structural buildings, e.g. materials for road making and asphalt. Although the journal will publish authoritative papers on theoretical and experimental research works and advanced applications, it may also feature, when appropriate: a) tutorial survey type papers reviewing some fields of civil engineering; b) short communications and research notes; c) book reviews and conference announcements.
