Assessing the impact of petroleum sludge ash on the compressive strength of fly ash-palm oil clinker geopolymer mortar

Oil industries are one of the most critical industries with substantial production and closely related to the public interest. Two major oil industries, namely petroleum and palm oil, represent primary sources of consumer groups in Malaysia. However, these sectors inevitably generate waste and re...
