The concrete ratio for plinth beam, Concrete is one of the most important building materials used in the construction industries for homes construction, low-rise, high-rise, commercial, office, apartment, or industrial buildings, bridges, dams, canals, retaining walls, and reservoirs. Without concrete, we cannot depict any structural structure types.
Calculation of the quantities of cement mortar in brick, conch, or plaster buildings:
To calculate the cement mortar, suppose we use one cubic meter of cement mortar, so the calculation procedures and steps are as follows:
Calculation of the quantities of cement and sand required in cement mortar – plaster/clam materials
1- Calculating the dry volume of materials required for a cement mortar of 1 cubic meter.
Looking at the voids in the sand, we assume that the material is a mixture of 60% voids. To obtain one cubic meter of wet cement mortar, you need 1.6 cubic meters of dry materials.
2- Calculating the volume of materials used in the cement mortar process is based on their proportions in the mixture. Suppose the ratio of cement to sand in the mortar is 1: x, where x is the required proportion of sand.
The concrete ratio for plinth beam and Concrete Grade Types, In this article, we know different types of concrete grades and their uses, such as the proportion of concrete mixing for column slab, roof, beam, foundation, and floor. Concrete mixing ratios are m5, m7.5, m10, m15, m20, and m25.
Everyone knows that to make concrete or even girder, you should mix a mixture of cement, sand, and aggregate in fixed proportions. Concrete has many uses in civil engineering works of tall and low-rise buildings, bridges, dams, bridges, retaining walls, and various types of piles.
Engineers use PCC (Plain Cement Concrete) on roads and house floors and use PCC as RCC to form roof slabs, foundation, base, beam, and column.
PCC Ratio for Base: – The concrete mix ratio generally used as PCC for the base is 1:3:6 (M10).
Types of concrete ratio for plinth beam properties according to their mixture
1) Nominal Mix Concrete
2) Concrete mix design
1) Nominal Mix Concrete:- A simple type of concrete mix people use in homes and forming of low-rise buildings, and engineers use fixed ratio M5, M10, m15, M20, and M25 in domestic purposes for various types of residential houses and bass formation for the foundation. Proportion in this grade of concrete has a fixed ratio of sandy cement and aggregate.
That is why engineers call it the nominal concrete mixture as the mixing ratio in M20 grade of concrete is 1: 1.5 : 3, where 1 part cement is 1.5 parts sand and three parts aggregate.
2) Mixed Concrete Design: – It is a standard type of concrete mix where expert engineers determine the mixing ratio of cement sand and aggregates according to the concrete and the strength requirements of concrete for tall buildings over forming bridge embankments for piles.
The engineer calculates and decides to calculate the mixing ratio mainly according to the strength requirements of the construction of civil works. So higher grade of m25, like M30, m35, m40, and m50, does not have a fixed mixing ratio of concrete which is why engineers call it design mix concrete.
