2015113American Concrete Institute Method of Mix Design ACI211.1 This method of proportioning was first published in 1944 by ACI committee 613. In 1954 the method was revised to include among other modifications the use of entrained air. In 1970 the method of mix design became the responsibility of ACI committee 211.

Concrete Mix Design or Mix Design of Concrete is a procedure of determining the relative quantities and proportions of different ingredients of the concrete i.e. Cement Water Fine Aggregate Coarse Aggregate with the object of producing homogeneous fully compactable concrete having required Strength and Properties with economy.
CONCRETE MIX DESIGN 161 The Relative Proportion Are Worked Out A trial proportion is taken and combined gradation is worked out for e.g. 35 fine aggregate 20 10mm down aggregate 45 20mm down aggregate. 161. CONCRETE MIX DESIGN 162 Combined gradation is plotted and pushed towards Ideal curve by increasing or decreasing the sand content
2020210ACI Mix Design 7. Estimation of coarse aggregate content The percent of coarse aggregate to concrete for a given maximum sie and fineness modulus is given by Table 4. The value from the table multiplied by the dryrodded unit weight the ovendry OD weight of coarse aggregate required per cubic foot of concrete.

For e.g. a concrete mix of proportions 124 means that cement fine and coarse aggregate are in the ratio 124 or the mix contains one part of cement two parts of fine aggregate and four parts of coarse aggregate. The proportions are

2017115Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement sand and coarse aggregates. For e.g. a concrete mix of proportions 124 means that cement fine and coarse aggregate are in the ratio 124 or the mix contains one part of cement two parts of fine aggregate and four parts of coarse aggregate.
2 The maximum sie of aggregate is also another important factor. Due to the internal bleeding of water in concrete the bonding can be poor for largesied aggregate. 20 mm downgraded aggregate can be used for making concrete of strength of 6000 psi or higher. However it can be reduced to 12 mm if the strength requirement is 10000 psi or more.

Concrete is a commonly used construction material which is the mixture of cement sand aggregate and admixtures blended with water. Concrete gets hardened with time and gains the strength and for the best results in a construction of your dream home mixing of concrete is said to be the most important process.

DIFFERENCE BETWEEN NOMINAL MIX CONCRETE AND DESIGN MIX CONCRETE. Design Mix Concrete is prepared by using step by step procedure given in IS102622009 codebook with reference to IS4562012 codebook. Cement sand and aggregate are calculated in terms of weightkg and their quantities are adjusted to suit different environmental conditions and for different construction needs.
Recycled concrete is created by breaking removing and crushing existing concrete to a preferred sie. It is commonly used as a base layer for other construction materials. Recycled concrete can be used as aggregate in new concrete particularly the coarse portion.
Can adopt this value while doing the concrete mix design those who are working other than highway project. But as per MORTH Table 1700.5 required target mean compressive strength 25 11 36.00 Nmm where 11 is the current margin. Adopt this value those who are working in highway project.

201418The effects of aggregate type sie and content on the behavior of normal and highstrength concrete and the relationships between compressive strength flexural strength and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed limestone aggregate sies of 12 mm h in. or 19 mm Y. in. and

2019521Normally fine aggregate sie ranges from 150 microns 106 m to 475 mm and the coarse aggregate ranges from sie fractions above 475 mm and the nominal maximum sies of the coarse aggregate are 10 mm 20 mm and 40 mm. Similar to most of the other concrete mix design procedures the facility is also available throughout the procedure
