Water Supply QC – Aggregate Grading Test Report Excel
The Water Supply QC – Aggregate Grading Test Report Excel is a professionally structured quality control documentation tool developed specifically for aggregate grading verification in water supply and Water Treatment Plant (WTP) projects. This QC sheet supports accurate, standardized, and audit-ready recording of aggregate gradation results used in RCC, PCC, and masonry works for water-related infrastructure.
Aggregate grading plays a critical role in strength development, workability, impermeability, and durability of concrete used in water-retaining and water-conveying structures. Improper grading can lead to segregation, honeycombing, increased permeability, and reduced service life. This QC format ensures that all coarse and fine aggregates used in intake structures, jack wells, aeration tanks, clariflocculators, filter beds, clear water reservoirs, sumps, pump houses, and pipelines supports conform strictly to IS grading requirements.
The Excel sheet follows a clean, consultant-friendly, audit-ready layout, with predefined input fields, sieve-wise percentage passing tables, specification limits, and comparison columns. Auto-calculation and auto-remarks are available in the Standard and Premium versions, helping QA/QC teams reduce manual effort and eliminate documentation errors during inspections and audits.
