A possible step toward creating sustainable concrete is using fly ash as a cement substitute material. The study work discussed in this paper aims to generate helpful information about the strength and durability of concrete containing a significant amount of fly ash. Laboratory tests were done on high-volume fly ash concrete (HVFAC) to examine its compressive strength, flexural strength, water absorption, abrasion resistance, impact resistance, and acid resistance. A total of six different concrete mixes were created by replacing varying percentages of cement with fly ash, ranging from 0 to 70% by mass. The laboratory tests revealed that increasing the percentage of fly ash in concrete by more than 30% reduces the compressive and flexural strengths. The addition of a significant amount of fly ash to concrete (between 40 and 70%) led to a decrease in its abrasion resistance and impact resistance, as well as an increase in its water absorption and an improvement in its resistance to acid. The outcome of this study extends the general concept of HVFAC and its applications to a wider range of construction projects. |
