Are you looking for 1:4:8 concrete calculator or lean concrete calculator? If yes, you’ve just arrived at the right place:

This M7.5 concrete Calculator is used to implement a form with three input fields (for length, width, and height). The form allows the user to enter values for the length, width, and height of a concrete element that has a mix design properties of 1:4:8. The input fields are implemented as range sliders. As the user adjusts the sliders, the corresponding values are displayed below the sliders in real time.

When you’ll change the values, the values that they have entered are used to perform a calculation for 1:2:4 or 25 MPa concrete mix and display the result. The code also includes some styling information for the form elements, as well as a tool tip that is displayed when the user hovers over the label for the height input field.

Note: it’s a dynamic form that means it will calculate the results in realtime as you enter values.

Height of concrete element (m):
Length of Concrete element (m)
Width of concrete element (m)

What is M7.5 Mpa Concrete or 1:4:8 concrete?

“7.5 MPa concrete” is a type of concrete with a compressive strength of 7.5 megapascals (MPa). The compressive strength of concrete is a measure of its resistance to crushing under a compressive load. It is expressed in megapascals (MPa), which is a unit of pressure. The higher the compressive strength of the concrete, the more resistant it is to crushing.

The “1:4:8” ratio refers to the proportions of cement, sand, and coarse aggregate used in the concrete mix. The numbers represent the parts of each material by volume. For example, in a 1:4:8 mix, there would be 1 part cement, 4 parts sand, and 8 parts coarse aggregate by volume. The proportions of these materials are typically expressed in terms of the volume of the dry materials, before water is added to the mix to initiate the chemical reaction that causes the concrete to harden.

How to calculate quantity for 1:4:8 concrete mix?

Here is a table that shows the calculations for estimating the amounts of cement, sand, and aggregate needed to produce 30 cubic meters (m3) of 1:4:8 concrete:

Material	Volume (m3)
Cement	1/13 x 30 m3
Sand	4/13 x 30 m3
Aggregate	8/13 x 30 m3

To calculate the volumes of the individual materials, you would divide the total volume of concrete required by the sum of the ratios of the materials in the mix. In this case, the sum of the ratios is 1 + 4 + 8 = 13.

Therefore, to calculate the volume of cement required, you would divide the total volume of concrete by 13 and then multiply the result by 1, which is the ratio of cement in the mix.

To calculate the volume of sand required, you would divide the total volume of concrete by 13 and then multiply the result by 4, which is the ratio of sand in the mix.

To calculate the volume of aggregate required, you would divide the total volume of concrete by 13 and then multiply the result by 8, which is the ratio of aggregate in the mix.
