Calculate concrete volume for rectangular or circular columns from cross-section dimensions, height, and number of columns in your structural frame.

Estimate concrete volume for rectangular RC beams from span, width, depth, and number of beams in a floor, roof, or bridge deck system.

Calculate the concrete volume for circular slabs, round pads, sonotube footings, and cylindrical elements from diameter and depth dimensions.

Calculate the concrete volume for cast-in-place stairs and steps from tread depth, riser height, stair width, and total number of steps.

Calculate the concrete volume for curbs, kerbs, and gutter sections from length, curb height, gutter width, and cross-section profile dimensions.

Calculate water quantity needed for your mix based on your target W/C ratio, cement content, and total concrete volume for any grade and application.

Enter a custom cement:sand:aggregate ratio and concrete volume to calculate the exact material quantities needed for any site-mixed or nominal mix concrete batch.

Design a concrete mix from target strength, exposure class, aggregate type, and cement grade to generate full batch proportions for any project specification.

Calculate the number of bricks needed for any facing or structural brickwork wall, with support for standard brick sizes, bond patterns, mortar joint, and waste.

Find out exactly how many cement bags you need for any concrete mix volume and ratio. Supports 25 kg, 40 kg, and 50 kg bags to match your local supplier.

Calculate total weight and length of reinforcing steel bars for slabs, columns, beams, and walls from bar diameter, spacing, and element dimensions.

Estimate the volume and weight of sand needed for any project in m³, yd³, or tonnes based on area, depth, and material density for concrete or bedding use.

Estimate the volume and weight of coarse and fine aggregate needed for a concrete mix from total volume, mix ratio, aggregate density, and moisture content.

Estimate total concrete cost per m³ including material, delivery, pump hire, placement, finishing, and waste. Supports all major currencies.

Calculate total material cost from quantity and unit price with waste percentage, delivery, labor, and VAT/tax support for any construction material type.

Estimate the total labor cost for any concrete or construction task from number of workers, daily rate, working hours, and total days on site.

Build a full project cost estimate combining concrete material, blocks, rebar, labor, formwork, equipment hire, and contingency into one total budget figure.

Calculate the all-in total cost for your concrete project including materials, ready mix delivery, pump, labor, formwork, and tax in one comprehensive output.

Estimate 28-day compressive strength from mix proportions and W/C ratio with unit conversion between MPa, N/mm², PSI, and kN/m² for any cement type.

Estimate concrete strength gain over time using the maturity method based on cement type, ambient temperature, and curing method for formwork striking decisions.

Calculate the exact number of transit mixer truck loads needed for any concrete volume based on truck capacity (4–10 m³) with full and part load breakdown.

Calculate the weight of any concrete volume from density (specific gravity) and convert between kg, tonnes, lbs, and short tons for load planning and formwork design.

Use the 3-4-5 triangle method to check that your formwork or foundation layout is perfectly square. Calculate the diagonal measurement needed for any rectangle.

Convert between millimetres, centimetres, metres, inches, feet, and yards instantly. Essential for working with mixed imperial and metric project drawings.

Convert between square millimetres, square metres, square feet, square yards, acres, and hectares for site area calculations and material coverage estimates.

Convert between cubic metres, cubic feet, cubic yards, litres, US gallons, and imperial gallons for concrete volumes, water, and liquid admixture quantities.

Convert between kilograms, grams, metric tonnes, pounds, short tons, and long tons for cement, aggregate, rebar, and concrete weight calculations.

Convert concrete strength and pressure values between MPa, N/mm², PSI, kPa, kN/m², and bar. Essential for comparing international concrete grade specifications.
