M 20 is used for RCC ( Reinforced Cement Concrete ) work such as Slab, Beams, Columns, footing etc (for mild exposure). Reinforced concrete tends to have a long service life with relatively low maintenance, and in turn, low maintenance cost. It should contain high compressive strength. The Full form of RCC is Reinforced Cement Concrete. It is measured by carrying out sieve analysis. gravel or crushed stone) with or without various admixtures, reinforcement, fibres, or pigments. Plain or Ordinary Concrete This is another concrete that uses the common mix design of 1:2:4 with its components of cement, sand and aggregates. The Advantages & Disadvantages of Reinforced Concrete The one big difference in its composition is the addition of steel rebar. However, it has other uses: As concrete on the bed flooring, under the column footings and on the walls below the beam. While M20 grade concrete is used for RCC works (for mild exposure) such as the construction of slabs, beams, columns, footings, etc. The fineness modulus (FM) of sand should remain 1.2 to 1.5. (ii) Laying of base concrete: What is the use of plain concrete? Set the concrete softly from one side. Plain Cement Concrete (PCC) has this weak characteristics in the presence of tension. Plums beyond 160 mm and any reasonable size may be utilised in PCC work up to the maximum limit of 20% by concrete volume when specially allowed by the engineer-in-charge. Used as Reinforced Cement Concrete (RCC). ? Estimating Types | Estimating Info | Estimating Process | BIM Estimating | HVAC | Architectural | News. A workable concrete should not demonstrate any segregation or bleeding. It is formed by mixing the basic components like cement, fine aggregate (generally sand) and coarse aggregate (generally stone pieces) in desired ratios. The use of short, discontinuous fibres to strengthen and toughen such materials, which are much weaker in tension than in compression, goes back to ancient times. But, if it is applied in the car parking area, the ratio will be changed to 1:2:4. What Are The Importance Of Setting Time Of Cement?
