| Summary: | Utilising industrial waste materials containing pozolanic compounds has been widely investigated for cement
replacement. Fly ash and microslica are materials having significant pozolanic compounds and can be used to
create ternary cementitious system. Slump of fresh concrete, porosity and compressive strength of hardened
concrete are study parameters which are used to investigate concrete characteristic which use ternary cementitious system. Three types of concrete mixtures, i.e. concrete mixture using original portland cement (OPC) as normal concrete, OPC-fly ash-microslica without superplasticiser, and OPC-fly ash-microslica with additional superplasticiser have been investigated to understand its concrete characteristics. Fresh concrete using fly ash and microslilica is proven to have higher slump and lower porosity than normal concrete. Compressive strength of concrete using fly ash and microsilica were higher than normal concrete. Utilising fly ash and microsilica as ternary cementitious system was found to have beneficial effect on fresh concrete, compressive strength and porosity of hardened concrete. |
