If we go with a slab at-grade foundation on soils with high clay content, we’ll experience a lot of movement over the years. So, the soil will be contracted and when got dry it would move. Similarly, when it’s wet it will expand so it has a tendency to move this house around....
slab-at-grade is not always a feasible choice. Slab-on-grade not only sets the house rest very low to the ground but also make it susceptible to flooding. Pier foundation on the other hand brings in plethora of benefits.
Unlike slab or slab-at-grade foundations, it brings inherent benefits like protection from flooding. It offers flexibility during an earthquake or seismic activity. At the same time, you can face problems with a crawlspace. If you won’t control the moisture penetration, you can … Read more...
Uses:It is used as Reinforced cement concrete (RCC) in the concreting of structural members like column, slab andbeamthat are subjected to mild exposure. It is also used in construction of domestic floor and foundations, internal floor slabs, garages anddriveways. Standard Grade of Concrete: Con...
M-7.5 gradeconcretewill give a total characteristicstrengthof 7.5 MPa. Advantages of lean concrete Lean concrete creates a uniform foundation surface and protects it from direct contact with soil. We use the lean concrete mostly under the foundation to protect ourslab. The level surface also helps...
Rigid pavement doesn’t go like this. It only has one layer of concrete slab that sits atop of the subgrade. For slabs with reinforcement, you may have an additional layer of lean concrete to have a flat surface for rebar installation. ...
M25 refers to a concrete mix with a compressive strength of 25 MPa (megapascals) after 28 days. Here is the general mix design for M25 grade concrete: Cement: 300-325 kg/m^3 Fine aggregate (sand): 600-675 kg/m^3 Coarse aggregate: 975-1050 kg/m^3 ...

concrete you need for the job (you can use above calculator for this estimation). Afterwards, you can choose the size of the concrete bag and the calculator will tell you the number of bags you need and also how much area it will cover depending on the thickness of the slab you choose...
The slab can also have different shapes in plan but it entirely depends on your loading conditions, architectural preferences, and other various design inputs. Square Footing Square footing includes reinforcement in both direction to resist shear forces and bending moment. An effective depth value amo...
