Concrete Mix Pro

ConcreteMix Pro is a professional concrete mix design application for civil and structural engineers, QA/QC personnel, site supervisors, and RMC plant operators. It performs complete mix design calculations per IS 10262:2019 (India), ACI 211.1-91 (US / International), and BS EN 206:2013 + BS 8500-2 (UK / Europe) — with full calculation transparency, so you can verify every step against the standard before use on site. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ MIX DESIGN ENGINES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • IS 10262:2019 — Indian Standard. Uses IS 456 exposure classes and IS 383 aggregate zones. • ACI 211.1-91 — American Concrete Institute. Uses ACI 318 exposure groups (F, S, W, C). • BS EN 206:2013 — European Standard. Uses X-class exposure system (XC, XS, XD, XF, XA), supports exposure combinations, k-value concept for SCMs, and BS 8500-2 designated concretes. Every calculation produces a step-by-step trace: the formula, the substituted values, the result, and the exact standard citation. Nothing is hidden. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Full 4-step mix design wizard: Project → Material → Workability → Review • Real-time input validation against the selected standard • Structured failure diagnostics — when a design fails, the app tells you exactly which limit was breached and what to change • Batch weights in SSD and field-adjusted states (accounts for aggregate moisture) • Per 50 kg bag weights for site batching • Professional 6-page A4 PDF report per mix design ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TRIAL BATCH TRACKING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Log trial batches against each mix design • Cube or cylinder specimens — the app applies the correct acceptance rules • 3-specimen sets at 7, 14, and 28 days with automatic averaging • Outlier detection per IS 456:2000 Clause 15.4 • PASS / FAIL acceptance evaluation • Corrective advice for under-strength trials • Optimisation suggestions for over-strength trials ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PROJECTS & REPORTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Group mix designs under projects • Export a full project PDF that aggregates every mix and every trial in one document • All generated PDFs are saved to Documents/ConcreteMixPro/Reports/ and shareable via any app on your device • Add your company name, address, contact, and designer name — they appear as branded headers on every report ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ COST ESTIMATION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Edit material rates in your local currency (60+ currencies supported) • Get per-m³ and per-bag cost breakdowns • See the percentage each material contributes to total cost ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ADDITIONAL TOOLS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Cross-Standard Comparison — run the same inputs through IS, ACI, and BS EN side-by-side, including a "cheapest mix" and "lowest cement" recommendation • Unit Converter — 9 categories including concrete-specific units (cement bags, bulk sand, bulk aggregate) • Standards Reference — IS, ACI, ASTM, and BS EN tables with cross-standard mappings • Full offline help and field-by-field guidance for every dropdown ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Structural engineers • Concrete technologists • QA/QC engineers • Site supervisors • RMC plant operators • Civil engineering students ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ All mix design calculations are transparent — every step shows its formula, substitution, result, and standard citation, so you can verify the output yourself before relying on it on site. This app is a professional tool. Mix designs must always be verified by trial batches on site before use in structural concrete. Some features are available in the free version with limits, and unlimited access is available via a one-time in-app purchase.
