WebNov 9, 2024 · 4.1 Pore Size Distribution. When metakaolin percentage was less than 20%, the porosity of the cement paste decreased [].More than 30%, an increase in porosity was notice which could be attributed to the ‘filler effect’ of fine metakaolin particles and also because of enhancing w/b ratios with increasing metakaolin content. WebApplication of Concrete Containing Metakaolin. Improving strength of lightweight concrete, decrease permeability, and releasing post tensioning earlier. Such advantages could be seen in Benicia Martinez Bridge …
