Store description excerpt
slump.IO is a fast, accurate concrete mix design calculator for civil and structural engineers, students, and site teams. Enter your requirements and get a complete, standards-based mix design in seconds — then export a professional PDF report. DESIGN TO YOUR STANDARD - ACI 211.1 (absolute-volume method) - IS 10262:2019 - BS 8500 / DoE — the DoE / BRE (BR 331) proportioning method - Custom mode — build a mix from your own binder, w/c ratio, and aggregate fractions EMBODIED CARBON See the CO₂ footprint of every mix, broken down by cement, SCMs, aggregates, water, and admixtures, using region-specific emission factors. Compare mixes and understand the impact of supplementary cementitious materials at a glance. PREDICTED STRENGTH (CUSTOM MODE) An on-device machine-learning model, trained on open and publicly available concrete datasets, estimates 28-day compressive strength from your mix — with honest confidence bounds. Mixes outside the model's trained range are flagged rather than given a false-confident number. BUILT FOR REAL WORK - Supplementary cementitious materials (fly ash, GGBS, silica fume) with k-value handling - Moisture and absorption corrections, batch quantities for any volume - Professional PDF reports you can share or archive - Works fully offline — nothing leaves your device - Complete data-source and citation transparency in Settings IMPORTANT slump.IO is an independent app and is not affiliated with or endorsed by ACI, BIS, BSI, BRE, or any standards body. All outputs are indicative aids for preliminary design, estimation, and education only. Every mix must be independently reviewed by a qualified engineer and validated through trial mixes before any field, structural, or commercial use.
