Concrete Calculator A1 PRO

About Concrete Calculator A1 PRO

Concrete volume, material quantities, mix design and costs in one app, built for civil engineers, contractors and site teams. 85 concrete shapes, six regional design codes, and every result broken down into cement bags, sand, coarse aggregate, admixture and water.

Type dimensions in whatever unit you are working in. Every field opens the app's own construction keypad with ft, in, yd, m, cm and mm on it, so "7 ft 8 in" goes in exactly as you would say it — no measurement mode to choose first. Results appear as you fill the form and switch between m³, ft³ and brass.

CONCRETE QUANTITY — 85 SHAPES • Columns — square, rectangular, round, hexagonal, octagonal, L-shape, T-shape and more • Footings — box, trapezoidal, stepped, combined, isolated, raft • Beams — simple, slope, stepped, continuous • Slabs — simple, slope, waffle, ribbed • Staircases — straight, dog-legged, L-shaped, U-shaped, spiral • Walls — retaining, compound, parapet and more • Roads, culverts, gutters, tubes, curbstones and plinth • Excavation volume and concrete blocks Every shape draws a schematic that highlights the exact dimension you are typing, so you always know which side you are on.

MIX DESIGN FOR 6 REGIONS • India — IS 456:2000 / IS 10262:2019 • USA — ACI 318 / ACI 211.1 / ASTM C39 • Canada — CSA A23.1 / A23.2 / A23.3 • Europe — EN 206 / Eurocode 2 • Gulf — BS 8500 plus municipality specs • Australia — AS 1379 / AS 3600 Choose your region once at setup and the right grades are ready. Add your own custom mixes and filter by grade.

CONCRETE TESTING — 29 TESTS WITH REPORTS • Cement — field test, fineness, consistency, setting time, soundness, compressive strength, chemical composition, heat of hydration • Fresh concrete — slump cone, slump flow, air content, compaction factor, V-funnel, L-box, J-ring, vee-bee, kelly ball and more • Hardened concrete — compressive, split tension, flexural, rebound hammer, ultrasonic pulse velocity • Aggregates — sieve analysis, water absorption, abrasion, impact and crushing value Export any test as a signed PDF or Excel report carrying your company details, and keep every filled report on file.

STRUCTURAL LOAD CALCULATOR 15 load cases across slabs, beams, walls and columns — dead load, live load, wind pressure, earthquake and snow.

COST ESTIMATOR AND BOQ • Set prices for cement, sand, aggregate, admixture and water • Automatic cost breakdown after every calculation • Build, manage and export Bills of Quantities on your own letterhead

CURING AND STATUS TRACKING • Track curing from day 0 to day 28 with a strength chart (MPa/PSI) to IS 456 and ACI 318 • Watering reminders and formwork removal warnings • Save multiple projects

SITE TOOLS Digital ruler, spirit level, compass, and Draw Volume for laying out an area and reading quantities straight off it.

ALSO INCLUDED • Unit converter — area, volume, length, weight and density • Formwork calculator • Custom calculators — build your own formulas • Scientific calculator with a paper tape • Study library — mix design, cement, aggregates, admixtures, checklists, work procedures, terminology and templates • Quizzes and a Question of the Day • Favourites, saved calculations and instant sharing • Six colour themes including a true dark mode • Works completely offline — no internet required

BUILT FOR PROFESSIONALS Civil engineers, site supervisors, project managers, building contractors, estimation engineers, quantity surveyors and architecture students — and homeowners planning a pour.
