The “M” refers to Mix and Number after M (M10, M20) Indicates the compressive strength of concrete after 28 days of curing and testing.. M indicates the proportion of materials like Cement: Sand: Aggregate (1:2:4) or Cement: Fine Aggregate: Coarse Aggregate.. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28
Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further
The pile cap is a mat-like structure which is made of cement, sand and small aggregates.; This mixture is placed in the required place, and it is supported by the framework to resist the whole structure from sagging and crack, this entire process is termed as shuttering and reinforcing.; In a pile, cap reinforcements are placed in the longitudinal section of the pile cap, and it creates a
Fineness modulus of coarse aggregate varies from 5.5 to 8.0. And for all in aggregates or combined aggregates fineness modulus varies from 3.5 to 6.5. Range of fineness modulus for aggregate of different maximum sized aggregates is given below
Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume
Aggregates Are Mainly Classified into Two Categories: Fine aggregate; Coarse aggregate; The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm, and the coarse aggregate is a gravel that has been crushed, washed and sieved so that the particles vary from 5 to 50 mm in size.The fine and coarse aggregate is delivered separately
Sep 19, 2019 As everyone knows cement, sand, and aggregates are the main components of concrete. Out of all three, aggregate works as a structural filler in the concrete mix. But its role is far more important and essential than that inferred in a simple statement. Coarse aggregate occupies 70% to 80% of the volume of concrete
Coarse aggregates. Take 1kg of the coarse aggregate test sample. Arrange the IS sieve in descending 25mm,20mm 12.5mm, 10mm, 4.75mm. Now fill the sample to the highest sieve and sieve well for up to 10 minutes. After completion of sieving, then weigh the aggregates retained in each sieve & note it down. Lab Report
Portland cement is the basic and most essential ingredient of concrete. Concrete is made when Portland cement creates a paste with water that binds with sand and rock to harden.Cement is a material like the glue that can bind together all other building materials and get hardened too. The cement is available in different like, 53 grades, 43-grade cement, OPC (ordinary Portland

In the field of construction, the term “Aggregates” simply represent materials like sand, crushed stones, broken bricks, gravel, chips, etc. which are used in the manufacture of traditional cement concrete, asphalt concrete, or various other composite building materials. Technically they are also called construction aggregates
