Mix represents concrete with designated proportions of cement sand and aggregate And the number following M represents compressive strength of that concrete mix in Nmm 2 after 28 days For example for M20 grade of concrete mix its compressive strength after 28 days should be 20 Nmm 2
Jun 24 2019018332Plain concrete It is the simplest kind of concrete that does not require any reinforcement The most commonly used mix is cement aggregates and water in the proportion 124 The density of this concrete is between 2200 and 2500 kgcubic metre whereas its compressive strength is in the range of 200 to 500 kgsquare centimetres
Making concrete it is important to use the correct concrete mixing ratios to produce a tough long life durable concrete mix To make concrete four basic materials you need Cement sand aggregate water and addmixture This concrete mix ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture
Mar 31 2020018332More water cement or sand can be added if the mixture is too wet or dry Below is an example of a sand to cement mix ratio recommendation from a cement manufacturer Concrete 1 part cement 2 parts concreting sand and 3 parts 20 millimeter aggregate Mortar 1 part cement 4 to 5 parts building sand
Manufactured Sand as an Alternative to use with Natural Sand in Concrete Mix Tej Prakash Kumawat 1 O P Reddy 2 1 MTech Scholar Department of Civil Engineering Suresh Gyan Vihar University Jaipur INDIA 2 Department of Civil Engineering Suresh Gyan Vihar University Jaipur INDIA ABSTRACT Scarcity of good quality Natural River sand
Concrete Mix Ratio by Volume Concrete mix ratios are prescribed ratio of cement sand and aggregate to get the desired strength in concrete The volumetric mix ratio of M20 concrete is 1153 hence 1 part of cement 15 part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete
Nov 21 2017018332River sand offers numerous applications including the mixing of plaster because particles are rounder than artificial sand and create a much smoother finish Weeks Sand amp Concrete has provided Cameron NC and the surrounding areas with topquality washed sand readymix concrete topsoil and gravel since 1984
manufactured sand when compared to reference mix ie 0 replacement reveal higher compressive strengths 2 In 50 replacement with admixture the compressive strength increases by 57 3 In 100 replacement of natural sand by crushed sand the compressive strength increases by 703 which is maximum 4 Concrete mix becomes harsh with

The proportions of cement sand coarse aggregate and water plays an important role in determining the fresh and hardended properties of concrete So care should be taken while calculating the amount of Cement Sand and Aggregate required for 1 Cubic meter of Concrete Method1 DLBD method to determine material requirement for 1 Cum concrete The DLBD Dry Loose
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 15 3 Total Part of the Concrete 1153 55 Parts Therefore Cement Quantity Cement Part Concrete Parts Concrete Volume
Bulking of Sand If the moisture is present in the sand then it makes the sand look bulkier which could result in inadequate sand proportion in the concrete ratio If we need to add 1m 3 sand in the concrete mix ratio we take 13 m 3 30 more The reason for that is the moisture content present in the sand makes it a little bulkier
In the present study we have selected M30 Grade of concrete mix To find out the effect of fineness modulus FM of sand on concrete sand of different FM from 20 to 30 is chosen Two sizes of coarse aggregate particles ie 20 amp 10 mm which are generally used in standard concrete mix were chosen for the investigations Concrete Mix Selected
