Trial mixes — IS 10262:2019 Cl 5.8

Cast Trial 1; adjust water/admixture for workability to form Trial 2; then Trials 3 and 4 at w/c varied by about plus/minus 10% with Trial 2's water content. Record slump, density, air content and 7/28-day strength for every trial.

Indicative tool — not a substitute for engineering judgement. Constants from IS 10262:2019 (Tables 1-5) and IS 456:2000 (Table 5, Cl 8.2.4.2) verified against controlled copies; verify the current edition in the BIS catalogue before contractual use. Final proportions require the Cl 5.8 trial series and project-specific materials.
