**PCC ratio for flooring footing Foundation & basement**, hi guys in this article we know about PCC concrete mix ratio for flooring, footing, Foundation & basement.

**PCC is plain cement concrete** made of mixture of cement sand and aggregate with water in a required proportion. First take required amount of cement, fine aggregate and coarse aggregate and mix properly with water.

**PCC used for** making pathway, pavement, concrete Road, it is also used for flooring, footing, foundation and basement construction, it is covering bed of concrete of any surface area.

**PCC ratio:-** PCC ratio used in construction are 1:5:10 (M5), 1:4:8 (M7.5), 1:3:6 (M10), 1:2:4 (M15), 1:1.5:3 (M20) & 1:1:2 (M25).

**PCC ratio 1:5:10 (M5):-** M stand for mix and numerical figure 5 is standard for characteristics of compressive strength that is 5N/mm2 in curing time of 28 days after casting, pcc ratio for M5 is 1:5:10, in which one part cement mix with 5 part sand and 10 part aggregate with water.

**Uses of M5 concrete grade**:- M5 is very lean mix concrete and can be used in any nonstructural work because it has less compressive strength, but it is banned today due to shrinkage issue. But it is usually used for trench fills and some strip Foundation footing, also in Pole footing to farm fences, for inferior work where strength is not important, concreting is done just for the sake of laying concrete mainly below ground level only to provide a level surface we can use concrete of grade M5.

**PCC ratio 1:4:8 (M7.5):**– M stand for mix and numerical figure 7.5 is standard for characteristics of compressive strength that is 7.5N/mm2 in curing time of 28 days after casting, pcc ratio for M7.5 is 1:4:8, in which one part cement mix with 4 part sand and 8 part aggregate with water.

**Uses of M7.5 concrete**:- M7.5 concrete as PCC can be used in learn concrete bases/mud and for ordinary masonry wall foundation.

**PCC ratio 1:3:6 (M10):-** M stand for mix and numerical figure 10 is stand for characteristics of compressive strength that is 10N/mm2 in curing time of 28 days after casting, pcc ratio for M10 is 1:3:6, in which one part cement mix with 3 part sand and 4 part aggregate with water.

**Uses of M10 concrete:-**M10 concrete as pcc can be used for patio slab, pathway and nonstructural work.

**PCC ratio 1:2:4 (M15):**– M stand for mix and numerical figure 15 is stand for characteristics of compressive strength that is 15N/mm2 in curing time of 28 days after casting, pcc ratio for M15 is 1:2:4, in which one part cement mix with 2 part sand and 4 part aggregate with water.

**Uses of M15 concrete:-** M15 concrete as pcc can be used for making permanent kerbs & floor blinding.

**PCC ratio 1:1.5:3 (M20):-** M stand for mix and numerical figure 20 is stand for characteristics of compressive strength that is 20N/mm2 in curing time of 28 days after casting, pcc ratio for M20 is 1:1.5:3, in which one part cement mix with 1.5 part sand and 3 part aggregate with water.

**Uses of M20 concrete**:- M20 concrete as PCC used for domestic floor, Foundation (where the weight of a structure will be lighter), workshop bases, garage, driveways & internal floor slab.

**PCC ratio 1:1:2 (M25):**– M stand for mix and numerical figure 25 is stand for characteristics of compressive strength that is 25N/mm2 in curing time of 28 days after casting, pcc ratio for M25 is 1:1:2, in which one part cement mix with 1 part sand and 2 part aggregate with water.

**Uses of M25 concrete:-** m25 concrete as PCC used for flooring, footing, Foundation basement, garage, weather resistant structure, heavy traffic pathway and Road.

**Flooring** is the general term used for a permanent covering of a floor, or for the work of installing such a floor covering. Floor covering is a term to generally describe any finish material applied over a floor structure to provide a walking surface.

**PCC ratio for flooring:-** PCC ratio for flooring are 1:3:6 (M10), 1:2:4 (M15), 1:1.5:3 (M20) & 1:1:2 (M25) used in construction. pcc ratio 1:3:6 (M10) & 1:2:4 (M15) are used for general flooring of surface like patio slabs, pathways, pavement kerbs & floor blinding and pcc ratio 1:1.5:3 (M20) & 1:1:2 (M25) are used for a strong flooring of surface like domestic floors, workshop base, garage, driveway, floor for heavy traffic road and pathway, weather resistant flooring structure and internal floor slabs.

Minimum grade of concrete used for flooring is M10 and maximum grade of concrete used for flooring is M30.

**Footing** are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench. The purpose of footings is to support the foundation and prevent settling. A footing is placed below the frost line and then the walls are added on top.

**PCC ratio for footing:-** PCC ratio for footing are 1:3:6 (M10), 1:2:4 (M15), 1:1.5:3 (M20) & 1:1:2 (M25) used in construction. PCC ratio 1:3:6 (M10) and 1:2:4 (M15) used for general footing (where the weight of structure will be lighter) and pcc ratio 1:1.5:3 (M20) & 1:1:2 (M25) are used for strong footing ( where the weight of structure will be heavier).

Minimum grade of concrete used for footing is M10 and maximum grade of concrete used for footing is M25.

In engineering, a **foundation** is the element of a structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (Geotechnical engineering) in the design of foundation elements of structures.

**PCC ratio for foundation:**– PCC ratio for foundation are 1:3:6 (M10), 1:2:4 (M15), 1:1.5:3 (M20) & 1:1:2 (M25) used in construction. PCC ratio 1:3:6 (M10) and 1:2:4 (M15) used for general foundation (where the weight of structure will be lighter) and pcc ratio 1:1.5:3 (M20) & 1:1:2 (M25) are used for strong foundation ( where the weight of structure will be heavier).

**PCC ratio for basement**:- basement is weather Shield moisture resistant structure, so higher grade of concrete can be used for construction of basement floor as PCC, PCC ratio for basement are 1:1.5:3 (M20) & 1:1:2 (M25) can be used in construction.
