26 Different Types of Concrete; [Its Classification, Uses

The ratio of essential constituents may be varied within wide limits. A very commonly used mix design, commonly known as Nominal Mix Design, is 1:2:4. Plain concrete is mostly used in the construction of pavements and in buildings, where very high tensile strength is not required. It is also used in the construction of Dams.

Concrete Mix Design - Design Mix Concrete & Nominal Mix

Mix design can be divided into following two categories. 1. Design mix concrete and 2. Nominal mix concrete. 1. Design Mix Concrete: When the proportions of concrete ingredients are decided by adopting certain established relationships ( based on assumptions from a lot of experiments) to produce the concrete it is known as design mix concrete.

types of concrete mix ratio design and their strengths

1) Nominal concrete mix ratio: In past years the specification for concrete was prescribed by the proportions of cement course. These mixes of fixed aggregate cement ratio ensure to have enough strength to use.But today nominal mixes offer the simplest way with the margin of strength and variability of different mixed ingredients for nominal concrete.

What is cement, sand, aggregate ratios in concrete mixing – we

2018-09-12 · The concrete shall be in grades designated Group Grade designation Characteristics compressive strength of 150 mm cube at 28 days, N/mm2. Ordinary Concrete---M10 M15 M20 Standard Concrete---M25 M30 M35 M40 M45 M50 M55 High Strength Concrete---M60 M65 M70 M75 M80 High performance concrete---M 90, M95 M100, M105, M110, M115, M120.


The nominal mix proportions varies based on the zones of sand and size of the course aggregates, so its batter to get with the design mix, But the mix design of concrete cannot be used for any reason on the work for grades of M-20 or lower than the M-20.

How to Calculate Quantities of Cement, Sand and Aggregate for

How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix (1:2:4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability.

What is Nominal Mix and Design Mix

But, usually they are selected on the volume basis and multiplied with 1.55 constant (in Nominal Mix Concrete Calculation) to obtain the bulk volume of the material. Design Mix Concrete: The concrete mix created under quality control on the basis of the strength, durability and workability is known as the design mix.

Different types of Concrete Mix Ratio

The “M” denotes mix. For example if the concrete mix is of M20 Grade then the compressive strength will be 20 MPa. Different types of Concrete Mix Ratio. Nominal Concrete Mix Ratios ...

Concrete Grades And Mix Ratio

Fundamental types of the concrete mix range from nominal mix, standard mix and design mix. There are different types of grades for concrete mixes like M5, M7.5, M10, M15, M20, M25, M30, M35, M40, M45, M50, M55, M60 as per IS 456-2000.

Understanding Nominal and Design Mixes

Design mix concrete is preferred to nominal mix. If design mix concrete cannot be used for any reason on the work for grades of M-20 or lower, nominal mixes may be used with the permission of engineer-in-charge, which however is likely to involve a higher cement content. Accordingly all concrete of above M-20 Grade for RCC work must be of ...
