Everything about the concrete itself. Design the mix to the code and exposure, grade and blend the aggregates, predict strength gain and maturity, model the temperature of a mass pour and its crack risk, work out shrinkage and creep, formwork pressure and plastic-shrinkage risk on a hot day, estimate service life against carbonation and chlorides, check strength results for compliance, and price the mix with its embodied CO₂ — with an A3 drawing set, Excel and report.
Scope & limitations
For preliminary design and education. Mix proportions are starting points that must be confirmed by trial batches with the actual materials; thermal, shrinkage and durability models are simplified, and the project specification governs.
What the concrete technology studio does
Mix design by the ACI 211.1 absolute-volume method (or the UK DoE approach): target mean strength from the code's margin, water–cement ratio from strength and exposure, water from slump and aggregate size, air, coarse aggregate from the fineness modulus, then the batch weights corrected for aggregate moisture, with supplementary materials and admixtures.
Aggregate grading against the standard envelopes with a blend optimiser for two to three aggregates, and exposure classes with the code's limits on water–cement ratio, strength, cement content and cover.
Strength gain with time and temperature (ACI 209 and EN 1992 curves, Nurse–Saul and Arrhenius maturity) and a one-dimensional heat-of-hydration model of a mass pour: core and surface temperatures, peak, differential and crack risk against the usual limits, with insulation and placing temperature to play with.
Shrinkage and creep to AS 3600, EN 1992-1-1, ACI 209 and AASHTO, formwork pressure (CIRIA R108 / AS 3610 and ACI 347), evaporation from the surface for hot or windy pours, carbonation and chloride ingress for service life, and strength compliance with a control chart.
Outputs: an A3 drawing set, an Excel workbook with live mix-design, maturity, shrinkage and formwork formulas, cost and embodied CO₂ per cubic metre, and a JSON model.
