Investigations Impact of Super Fly Ash Plus onConcrete Mechanical Behavior

Pozzolanic materials refer to silica and alumina substances that form strong andpermanent compounds with adhesive properties when mixed with water and lime. Asignificant advantage of using pozzolanic materials is their ability to reduce pollutantsduring cement production while also preventing surface cracking and enhancing resistanceagainst chemical attacks and sulfates. Fly ash (FA), a common byproduct of coalcombustion is a green environmentally-friendly material and pozzolanic additive that cansubstitute a portion of cement and help reduce pollution associated with cement production.In this paper, we present the findings of an experimental study that utilized a pozzolanicadditive called Super Fly Ash Plus (SFAP) as a partial substitute for cement. To achievethis, in conjunction with identification through X-ray fluorescence (XRF) analysis, theeffects of SFAP contents of ۰, ۵, and ۱۰% were individually assessed on the compressivestrength, and modulus of elasticity measurements for a curing age of ۲۸ days. The findingsindicate that when the Water/Cement (W/C) and aggregate grading remain constant,increasing the SFAP content enhances the effectiveness of the concrete. Furthermore,SFAP potentiated an increase in the compressive strength, elasticity modulus, and longtermdurability of concrete. The most significant improvements were observed at a ۱۰%content.
