What Is The Best Concrete Mix Ratio For Roof Slab, Beam & Column

In this article we know about best mix ratio for concreting work like roof slab, column and beam for any type of residential and commercial building. As we know concrete mix ratio is design according to load acting on the structure.

Concrete is one of the most important building material used in construction industries for building a homes, low rise building, high rise building, commercial building, office building, apartment, industrial building, bridge, Dams, Channel, retaining walls and reservoir. Without concrete we can’t imaging any type of construction structure.

Concrete is two types:-

1) Plain cement concrete which is also known as PCC made of mixture of cement, sand, aggregate and water in definite and required proportion with desirable strength,

2) Reinforced cement concrete which is also known as RCC, if plain cement concrete provided with steel reinforcement known as rainforest cement concrete.

Best mix ratio for concrete

It all depends on type of structure, whether it is plain cement concrete or reinforced cement concrete. Best mix ratio for concrete is 1: 2: 4 (Cement, Sand, aggregate), in which one part is cement, 2 part is fine aggregate or sand and 3 part is coarse sand or aggregate. This is the safest best mix ratio for concrete or PCC for any type of construction where steel is not provided.

If concrete is provided with steel bar or reinforced, the safest best mix ratio for RCC concrete is 1: 1.5: 3 (Cement, Sand, aggregate), in which one part is cement, 1.5 part is fine aggregate or sand and 3 part is coarse sand or aggregate. This is the safest best mix ratio for rcc concrete for house construction where steel is provided.

Best concrete mix ratio for roof slab

Roof slab is horizontal RCC structure used to cover top of house, made of concrete provided with steel reinforcement. Generally, concrete mix ratio 1: 2: 4, 1: 1.5: 3 or 1: 1: 2 (Cement, Sand and aggregate) used for roof slab construction, but safest best concrete mix ratio for roof slab used is 1: 1.5: 3 (Cement, Sand and aggregate), in which one part is cement, 1.5 part is sand and 3 part is aggregate.

Best concrete mix ratio for rcc beam

Beam is horizontal load bearing structural member of concrete fiber provided to resist the load coming from roof slab and transfer all coming load safely to column. Generally, concrete mix ratio 1: 1.5: 3 or 1: 1: 2 (Cement, Sand and aggregate) used for rcc beam construction, but, in house, typically, most common, safest best concrete mix ratio used for RCC beam is 1: 1.5: 3 (Cement, Sand and aggregate), in which one part is cement, 1.5 part is sand and 3 part is aggregate.

Best concrete mix ratio for rcc column

Column is vertical load bearing structure of concrete fiber provided with steel reinforcement to resist the load acting on it, it safely transfer all incoming load to bed of soil.

Generally, concrete mix ratio 1: 1.5: 3 or 1: 1: 2 (Cement, Sand and aggregate) used for rcc column construction, but, in house, typically, most common, safest best concrete mix ratio used for RCC column is 1: 1: 2 (Cement, Sand and aggregate), in which one part is cement, 1 part is sand and 2 part is aggregate.
