A typical quarry dust could be designated 0/4 G A 85 G TC 20.

However for mass concrete aggregate sizes upto 150 mm can be used. However the decision would also be influenced by the cost and availability of different sizes of fractions.

How to Calculate Quantities of Cement, Sand and Aggregate In the step 3 of "How To Calculate Quantities Of Cement, Sand And Aggregate For Nominal Concrete Mix (1:2:4)" you have calculated that: 01 cum of concrete will require Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags Sand required = 115/0.167 = 688 Kgs or 14.98 cft Aggregate required = 209/0.167 = 1251 kgs or 29.96 cftWhat is Grading of Aggregates and Grading Limits?Grading of aggregates are determination of particle size distribution of aggregates. Grading of aggregates is an important factor for concrete mix design. These affect the concrete strength as well as durability. Proper grading is important for concrete construction. Following tables provides
What should be the ratio of 20mm to 10mm size aggregates It could be seen that nominal mixes cannot have a fix conventional proportions such as 1:2:4 or 1:1.5:3, but may vary according to maximum size of coarse aggregate and grading of fine aggregate. Hence nominal mixes are also needed to be designed according to the sizes of aggregates available at site.WHAT IS THE GRADING LIMITS FOR COARSE AGGREGATES The grading of coarse aggregate may be varied through wider limits than that of fine aggregates, since it does not affect the workability, uniformity and finishing qualities of concrete mix. As per IS383 the grading limit of coarse aggregate, both for single size as well as
Aggregates in Concrete University of WashingtonAggregate Characteristics Affecting Concrete Behavior Concrete Technology 22 B. Aggregate Grading(Cont'd) The fineness modulus can be considered as a weighted average size of a sieve on which the material is retained, keeping in mind that the sieves are counted from the finest. For instance, a fineness modulus of 4.00 can beIS 383 (1970): Specifiion for Coarse and Fine IS 383 (1970): Specifiion for Coarse and Fine Aggregates From Natural Sources For Concrete [CED 2: Cement and Concrete] Indian Standard SPECIFICATION FOR aggregate grading may, in some circumstances, depend on the grading and 2.1 Fine Aggregatc Aggregate most of which passes 4.75mm IS Sieve
A Detailed Guide on Grading of Aggregates. civilseek.comGrading of Aggregates. Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates.The aggregate sample is sieved through a set of sieves and weights retainedOn Aggregate Grading National Ready Mixed Concrete On Aggregate Grading (2.36 mm) sieve divided by the total aggregate weight, expressed as a percent.

Effect of coarse aggregate grading on the ASR expansion Effect of coarse aggregate grading on the ASR expansion and damage of concrete. and recrystallized sandstone was most damaging in the size range of 10–20 mm. These studies indie that the size of the coarse aggregate can influence the ASR expansion and damage of concrete. , the concrete prism test (CPT), prescribes a size range of 4Effect of aggregate grading on pervious concrete propertiesEffect of aggregate grading on pervious concrete properties Fresh and hardened pervious concrete properties are experimentally determined in the paper.

The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:Y. in.), and
4 20 mm aggregate grading,CHAPTER 4 AGGREGATES Civil Engineering Department4.5.10 Grading Requirements • The purpose of sieve analysis is to determine whether or not a particular grading is suitable. The related problem of grading is the combining of fine and coarse aggregates so as to produce desired grading (See Table 4.5, 4.6).
