Sugarcane Baggage Ash Used As Locally Available Cementitious Material For Enhancing The Property Of PQC

Abstract

Pavement Quality Concrete (PQC) in rigid pavements is governed primarily by flexural performance and durability under chloride, sulfate, abrasion and fatigue actions. This paper evaluates sugarcane bagasse ash (SCBA)—a high-silica agro-industrial by-product—as a partial cement replacement for PQC in Indian conditions. After detailing PQC performance criteria from IRC standards, we synthesise recent evidence on SCBA processing (controlled burn + grinding), optimal dosage (typically 5–15% by mass of cement), and effects on fresh, mechanical and durability properties. We then propose a PQC-oriented experimental programme (flexural strength–driven mix design) including RCPT/sorptivity, sulfate resistance, and wheel-track abrasion, alongside microstructure tests (XRD/SEM). The expected outcome is that well-processed SCBA at modest dosages can meet or exceed IRC flexural targets while reducing permeability and life-cycle CO₂. Findings aim to inform state highway agencies on adopting locally available SCBA for PQC.
