Traço Certo: Calculadora Obra

Traço Certo is the construction calculator for those working on the construction site. It calculates the concrete and mortar mix and shows how much cement, sand, stone, lime, and water you will need. It uses construction terminology, has large buttons, and requires few taps to get the result.

CONCRETE AND MORTAR CALCULATOR
• Concrete (15, 20 and 25 MPa) for slabs, beams, columns, footings and floors
• Plastering
• Rendering
• Block and brick laying
• Floor leveling (subfloor)

WHAT IT SHOWS
• Concrete mix per bag of cement and per batch (400 L mixer)
• How many batches you will make and how much will be in the last batch
• Quantity of material for the entire job: cement in bags, sand and gravel in m³, water in liters
• Measurements in 18 L cans, with half a can written out in full
• Water to add, already discounting the moisture from the sand
• Quantity of blocks and bricks with breakage, during laying
• Optional cost: you enter the prices and see the total and the cost per m² or m³

DON'T KNOW THE VOLUME?

Enter the dimensions of the element (slab, beam, column, footing, pile, wall, floor) and the app calculates.

SHARE
Send the completed mix design via WhatsApp to the bricklayer or print a summary on an A4 sheet.

WORKS WITHOUT INTERNET
Once opened, it works offline, good for construction sites with weak signal.

NO REGISTRATION AND NO ADS
It doesn't ask for login, doesn't collect data, and has no advertising. What you type stays only on the device and disappears when you close it.

WHERE DO THE NUMBERS COME FROM? Mix designs and consumption figures are based on SINAPI compositions and usual ABNT standards. The results are reference estimates for small construction projects: they do not replace structural design, technical supervision, or laboratory dosage.

For bricklayers, foremen, engineers, engineering students, and anyone building or renovating their own home.
