Construction Calculator

A construction calculator is fundamental to correctly plan the building of any HOUSE DESIGN and its corresponding tasks.

You will find estimator tables with construction material calculator:

  • masonry walls,
  • slabs,
  • columns,
  • stairs volume calculator
  • foundations,
  • reinforcing steel rods,
  • roof
  • material weigh
  • preparation of concrete and mortar. 

Let’s see…

Materials Calculation for Solid Concrete Slab

Variants of material calculations. You will see HOW MUCH CONCRETE DO YOU NEED.

You can see more information, which includes details on .

Materials Calculation for Solid Concrete Slab

Table of Concrete Calculator for a Slab

A % of waste is included (cement: 5%, sand: 10%, gravel: 10%).

Concrete Calculator

How to calculate construction materials to build foundations and footings, slabs, columns, sidewalks, curbs and more.

In this section we can find a real CONCRETE CALCULATOR in different units of measurement.

 Concrete Calculator

Straight Stair with Concrete Volume Calculator

Concrete stairs calculators, with solid design, straight, 2 sections, with steps and central beam. An example is shown (solid straight staircase.)

In this section we can find the AMOUNT OF VOLUME AND CEMENT FOR STAIRS of different types and designs.

Straight Stair with Concrete Volume Calculator

Calculate How Much a Bag of Cement Yields

In this section you will learn HOW MANY BAGS OF CEMENT TO MAKE 1M3 OF CONCRETE. Concrete and mortar mix ratios are included.

You can also make your own calculations. For example, find out HOW MANY BAGS OF CEMENT PER SQM, is needed.

Rebar Weight Calculation

You will see how many rods a ton of steel brings, in a REBAR SIZE CHART WITH STEEL BAR WEIGHT calculator.

At the same time, you can calculate the weight of corrugated and smooth rods. Prices of reinforcing steel bars per linear meter and ton are included.

Rod Weight Calculation

Table to Calculate Cement, Sand, Gravel and Water Volume (per m³ of Concrete)

In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.

Cement Bag Calculator per m3 of Mortar

Calculation Table for Cement, Sand and Lime Hydrate (per m³ of Mortar)

A % of shrinkage is included (cement: 5%, sand: 10%, lime: 5%).

Block and Brick Material Wall Calculator

Calculating the amount of materials needed to build a wall is a fairly simple task.

Use the following WALL MATERIAL CALCULATOR PER SQM – SQ FT with formulas and free tables.


Quantity of Materials per m2 of Wall

Material Calculator for Flooring

It is important to know the calculation of materials to build a floor, depending on whether it is ceramic, granite, polished cement, bricks… You will need to know the total area to calculate and thickness.

Use the construction materials tables to calculate MATERIALS PER SQM OF FLOORING of different types.

Material Calculator for Flooring

Calculate Material for the Construction of a Bedroom

At the same time, you can calculate all the materials to build a room, according to its design, roof…

To know HOW MUCH MATERIAL YOU NEED TO BUILD A ROOM follow this link and see different alternatives. Here you can estimate 1 TON HOW MANY BAGS OF CEMENT ARE.

Specific Weight of Materials

Tables of specific weights of different materials are shown, organized by categories.

Click on the link for more information. You will find interesting calculators with all the WEIGHTS AND DENSITIES OF THE MATERIALS.

Mix Ratios

You must bear in mind that the same name or type of material may have slightly different characteristics and properties, depending on the quality of its production, the manufacturer, and the raw materials with which it is produced. This is more notable, in the preparation of mortars and concretes.

The earth’s crust is very rich in its physical-chemical composition. Each country or region owns soils with particular properties.

Therefore, the cements and aggregates used in the preparation of concrete vary in their properties and resistance. To this, we can add that there are different ways and “experiences” to manufacture materials and build houses.

All this means that there are as many dosages of mortar and concrete, as there are plants to produce their raw materials.
