What does 20mm down aggregate mean Quora

A2A 20mm down aggregate/ coarse aggregate means most of the particle will pass through 20mm sieve and the particles of smaller size will retain in 4.75mm sieve. The stone dust particle less than 150 micron are generally not recommended since it

What is Grading of Aggregates and Grading Limits

Join now 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 details for grading limits of aggregates.

What Is Grading Of Aggregates And Its Limits Civil Planets

Based on the aggregate gradation, we can choose the right aggregates for construction. For example, 40mm aggregates are used in PCC and 20mm aggregates are RCC. The smaller size of aggregates gives a larger surface area which provides good bonding to

Sieve Analysis of Coarse Aggregate Gradation of Aggregate YouTube

Sieve Analysis of Coarse Aggregate 20mm as per IS 2386 part 1 Size of sieves to be used: For fine aggregate 4.75mm, 2.36mm, 1.18mm, 600 microns, 300 micr

Table 4 from Effect of Gradation of Coarse Aggregate on Strength Properties of Geo Concrete Semantic Scholar

Table 4: Split tensile strength of C.C and GPC of coarsely graded coarse aggregate 20mm down quotEffect of Gradation of Coarse Aggregate on Strength Properties of Geo Concretequot


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 graded should be as per the table given below.

Gradation of Coarse Aggregate by Sieve Analysis Civil Engineering Portal Biggest Civil Engineering Information Sharing Website

Aggregate gradation is defined as the particle size distribution of both the stone and sand present in the concrete matrix. This property of aggregate has been heavily undergoing research for over a century but the effects of which on concrete properties is still somehow misunderstood.

How To Do Sieve Analysis Of Aggregate

The most important test is the sieve analysis of aggregate, whether it is 20mm, 10mm, 5mm and 1mm sizes. The crucial thing is I have to do it every delivery of aggregate and as per the frequency of sieve analysis, which is written in this article frequency of tests.
