RISPore Structure Changes of Blended Cement Pastes Containing Fly Ash, Rice Husk Ash, and Palm Oil Fuel Ash Caused by Carbonation
Publisher: American Society of Civil Engineers
Abstract: In this paper, the effects of carbonation on pore structure of blended pozzolan cement pastes were investigated. Ordinary Portland cement (OPC) was partially replaced with ground palm oil fuel ash (POA), ground rice husk ...
Strength and Carbonation Model of Rice Husk Ash Cement Mortar with Different Fineness
Publisher: American Society of Civil Engineers
Abstract: This paper presents a study of the strength and carbonation resistance of mortar made with portland rice husk ash cement by some accelerated short-term techniques in 5% carbon dioxide. Three finenesses of rice husk ashes, ...
Use of Palm Oil Fuel Ash to Improve Chloride and Corrosion Resistance of High-Strength and High-Workability Concrete
Publisher: American Society of Civil Engineers
Abstract: This paper presents the use of palm oil fuel ash as a pozzolanic material in producing high-strength and high-workability concrete. Portland cement Type I (CT) was partially replaced with ground palm oil fuel ash (PA). PA ...
High-Calcium Bottom Ash Geopolymer: Sorptivity, Pore Size, and Resistance to Sodium Sulfate Attack
Publisher: American Society of Civil Engineers
Abstract: The resistance to sulfate attack, compressive strength, sorptivity, and pore size of high-calcium bottom ash geopolymer mortars were studied. Ground lignite bottom ashes (BAs) with median particle sizes of 16, 25, and 32 μm ...
