In compare to Portland cement, geopolymer have much lower CO2 emissions, which led to growing interest in their use as an environmentally sustainable binder. The investigation of the strength in compression and durability characteristics of geopolymer composite produced at various calcined clay and ground granulated blast furnace slag (GGBS) proportions (up to 50:50) with 12M of sodium hydroxide and ratio of sodium silicate to sodium hydroxide as 2. The strength of the produced composites was evaluated after 7, 28, 56 and 90 days of ambient air curing. The durability characteristics were evaluated using Rapid Chloride Permeability Test (RCPT), acid and sulfate attack using 5% MgSO4 and 5% H2SO4 solutions respectively and for the integrity using ultrasonic pulse velocity (UPV) test. Test results showed that the developed GPC (Geopolymer composite) has several advantages over standard concrete. The strength in compression (MPa) of the SC100 (standard concrete) as compared to Geopolymer Concrete in Compressive strength was increased by replacing GGBS with calcined clay up to 10%. At 56 and 90 days, the compressive strength of 10% calcined clay samples were improved by 20.15% and 21.60% respectively as compared to the SC100. Correlations showed that strength is having a strong relationship with the chloride ion permeability and the pulse velocities.

Abstract


In compare to Portland cement, geopolymer have much lower CO2 emissions, which led to growing interest in their use as an environmentally sustainable binder. The investigation of the strength in compression and durability characteristics of geopolymer composite produced at various calcined clay and ground granulated blast furnace slag (GGBS) proportions (up to 50:50) with 12M of sodium hydroxide and ratio of sodium silicate to sodium hydroxide as 2. The strength of the produced composites was evaluated after 7, 28, 56 and 90 days of ambient air curing. The durability characteristics were evaluated using Rapid Chloride Permeability Test (RCPT), acid and sulfate attack using 5% MgSO4 and 5% H2SO4 solutions respectively and for the integrity using ultrasonic pulse velocity (UPV) test. Test results showed that the developed GPC (Geopolymer composite) has several advantages over standard concrete. The strength in compression (MPa) of the SC100 (standard concrete) as compared to Geopolymer Concrete in Compressive strength was increased by replacing GGBS with calcined clay up to 10%. At 56 and 90 days, the compressive strength of 10% calcined clay samples were improved by 20.15% and 21.60% respectively as compared to the SC100. Correlations showed that strength is having a strong relationship with the chloride ion permeability and the pulse velocities.
