Testing & Inspection
Testing tells you what the concrete actually became — not what the mix design promised. This guide walks the inspection toolkit: when a rebound hammer is a screening tool and never a strength verdict, what UPV velocity grading really means (IS 516 Part 5/Sec 1:2018), how cores are taken and judged against IS 456 Cl 17.4, and how chloride and carbonation profiles are built and read.
Every method answer names the governing standard and the free calculator that turns its numbers into decisions.
