Bioactivity enhancement of calcined kaolin geopolymer with CaCl2 treatment [PDF]
This paper reports that surface treatment with CaCl2 enhances the bioactivity of a calcined kaolin geopolymer. Calcined kaolin, NaOH solution, sodium silicate solution, and heat curing were used to form geopolymer pastes.

Over the past decades, studies have demonstrated the effectiveness of polyethylene (PE) and PE terephthalate (PET) as an alternative to aggregates in enhancing concrete performance. This research aims to predict the compressive strength (CS) of PE and PET‐incorporated concrete by evaluating the influence of key factors, including cement content, PET ...
