CONCRETE QUANTITY — 85 SHAPES Columns, footings, beams, slabs, staircases, walls, roads, culverts, gutters, tubes, curbstones, plinth, excavation and blocks. Every result is broken down into cement bags, sand, coarse aggregate, admixture and water, in m³, ft³ or brass. Each shape draws a schematic that highlights the dimension you are typing.

TYPE IN ANY UNIT Every field opens a construction keypad with ft, in, yd, m, cm and mm, so "7 ft 8 in" goes in exactly as you would say it. No measurement mode to switch.

MIX DESIGN FOR 6 REGIONS India IS 456 / IS 10262 · USA ACI 318 / ACI 211.1 · Canada CSA A23.1 · Europe EN 206 / Eurocode 2 · Gulf BS 8500 · Australia AS 1379 / AS 3600. Pick your region once, add custom mixes, and every calculator reads the same mix library.

CONCRETE TESTING — 37 TESTS WITH REPORTS Cement, fresh concrete, hardened concrete, aggregates, water and admixtures: slump, cube strength, rebound hammer, UPV, sieve analysis, setting time, chloride content and more. Export signed PDF or Excel reports with your company details and file them against a project.

COST ESTIMATOR AND BOQ Set material prices, get an automatic cost breakdown, apply a wastage allowance (2–5%) across every result, and build Bills of Quantities on your own letterhead. Calculators add straight into a project BOQ, and the structural calculators export a PDF with drawing and quantities.
