Porosity is the formation of bubbles in the weld.
Concrete is usually alkaline and porous. Thus it may be attacked by acids - even mild ones such as milk!The porosity means that materials such as motor oil will be absorbed.Sealing the surface with an impermeable coating will help in avoiding these problems. This approach will work even better if the concrete surface has been made more dense and smooth by surface working before it has set.
There is no way to calculate cost for a square foot of concrete (?" w x ?" l). In order to calculate cost you need to first calculate volume which requires a third dimension of height (?" w x ?" l x ?" h). Concrete is usually sold by the cubic yard (36" wide x 36" long x 36" high). Another factor in calculating price of concrete is distance to delivery location.
Considering the different applications and methods of concrete construction, you really can't calculate it that way.

The electrical resistivity of concrete is a measure of its ability to resist the flow of electrical current. It is influenced by factors such as the composition, moisture content, and curing conditions of the concrete. Higher resistivity values generally indicate better quality concrete with lower porosity.
big particles=low porosity small particles=high porosity
length*breadth*depth of the structure=...........m3 of concrete is needed. .
To calculate the amount of concrete needed for a project, you need to determine the volume of the area to be filled with concrete. This can be done by multiplying the length, width, and height of the area. Once you have the volume, you can then calculate the amount of concrete needed by dividing the volume by the coverage area of one cubic yard of concrete. This will give you the total number of cubic yards of concrete needed for the project.
Silpozz reduces concrete porosity, minimizing shrinkage and the risk of cracking, and ensuring structural integrity over time.
The designers calculate the potential effects of cracking on the concrete columns.
To test a soil's porosity, you can conduct a simple experiment by measuring the volume of water that a known mass of dry soil can absorb. Calculate the porosity by dividing the volume of water absorbed by the total volume of the soil sample, then multiply by 100 to get a percentage. Additionally, you can use a soil moisture meter to directly measure the porosity of the soil by inserting the probe into the soil and recording the moisture content.

The Porosity test is typically carried out on a sample of material to determine the amount of open space within its structure. This test is commonly performed during the quality control process of manufacturing products like ceramics, concrete, or metals to ensure uniformity and desired properties.
