Durability properties of inorganic polymer concrete using fly ash and slag

Concrete mix designs used a total binder content of 430 kg/m3 with a nominal consistence of 180 mm. Fresh concrete assessment included slump and rheology testing. Hardened performance of concrete was assessed at 28 days by measuring density, compressive strength, elastic modulus and drying shrinkage. Durability properties were assessed at 28 and 90 days and included effective porosity, oxygen permeability and chloride resistance.
