Strength of Binary and Ternary Blended Cement Pastes Containing Palm Oil Fuel Ash and Metakaolin Exposed To Sodium Sulphate
The compressive strength of binary (BBCP) and ternary blended cement pastes (TBCP) containing Palm Oil Fuel Ash (POFA) and Metakaolin (MK) exposed to 3 % sodium sulphate solution has been studied. The ordinary Portland cement (OPC) was partially replaced with POFA and MK on mass-for-mass basis....

| Summary: | The compressive strength of binary (BBCP) and ternary
blended cement pastes (TBCP) containing Palm Oil Fuel Ash (POFA) and
Metakaolin (MK) exposed to 3 % sodium sulphate solution has been
studied. The ordinary Portland cement (OPC) was partially replaced with
POFA and MK on mass-for-mass basis. All specimens were first cured for
28 days in normal water and subsequently subjected to full immersion in
sodium sulphate solution for 150 days for the compressive strength
evaluation. The results show that partial replacement of cement with POFA
and MK improved the durability of the cement pastes by reducing the
damage caused by sulphate attack. |
