Geopolymer Mortar Workability Tests with Two Alkaline Activator Solutions

A. M. Oliveira evaluated the influence of alkaline activator solution viscosity on geopolymer mortar workability. Eight mortars were made using commercial metakaolin, sand, and two types of activator solution. Workability was assessed using flow-table and squeeze-flow tests based on Brazilian standards NBR 13276 (2016) and NBR 15839 (2010).

Use Cases

• Modeling mortar workability based on activator solution viscosity mentioned in the description
• Comparing flow-table and squeeze-flow test results for geopolymer mortars
• Optimizing geopolymer mix designs for specific workability requirements

Strengths

• Workability was evaluated using two standardized test methods: flow-table (NBR 13276) and squeeze-flow (NBR 15839).
• The study tested eight distinct mortar formulations using commercial metakaolin and two types of alkaline activator solution.
