What is sieve analysis of fine aggregate?

The whole procedure of sieve analysis is to determine the particle size distribution of the fine aggregates and determine whether it is suitable to use in concrete mixing.

What is sieve analysis of fine and coarse aggregates?

The sieve analysis determines the gradation (the distribution of aggregate particles, by size, within a given sample) in order to determine compliance with design, production control requirements, and verification specifications.

Is code for sieve analysis for fine aggregate?

to IS : 460-1962 Specification for Test Sieves ( Revised) shall be used. 2.2. 2 Balance – The balance or scale shall be such that it is readable and accurate to 0.1 percent of the weight of the test sample.

Is sieve for fine aggregate?

The sieves normally used are the standard 8 inch (200 mm) sieves. With Fine Aggregate the coarse sieve or the 3/8” (9.5 mm) sieve at the top; each sieve below is finer; and the finest sieve, a No. 200 (75 µm) is at the bottom. A pan is placed below to retain any fine material that may pass this sieve.

What are the types of fine aggregate?

Types of Fine Aggregate

• Coral Sand.
• Glass Sand.
• Immature Sand.
• Gypsum Sand.
• Ooid Sand.
• Silica Sand.
• Pit Sand.
• River Sand.

What is the advantage of sieve analysis for fine aggregates?

Some advantages of the sieve analysis include easy handling, low investment cost, accurate results in a reasonably short period of time and the possibility of separating the particle size fractions. Figure 1. A commercial sieve shaker with a stack of various sieve sizes.

What are fine aggregates?

Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼” or smaller. Frequently referred to as washed concrete sand or manufactured sand, C33 refers to the grading or size of the material.

How do you classify aggregates?

Aggregates are classified according to shape into the following types

• Rounded aggregates.
• Irregular or partly rounded aggregates.
• Angular aggregates.
• Flaky aggregates.
• Elongated aggregates.
• Flaky and elongated aggregates.

How many zones are in fine aggregate?

1 : M sand There are four grading zones for fine aggregates such as grading zone I, II, III, and IV. It is recommended that fine aggregate conforming to Grading Zone IV should not be used in reinforced concrete unless tests have been made to ascertain the suitability of proposed mix proportions.

What is the size of fine aggregate?

4.75mm
The size of fine aggregates is defined as 4.75mm or smaller. That is, aggregates which can be passed through a number 4 sieve, with a mesh size of 4.75mm. Fine aggregates include things such as sand, silt and clay.

How is sieve analysis of fine aggregates performed?

Sieve analysis of fine aggregates is one of the most important tests performed on-site. Aggregates are inert materials that are mixed with binding materials such as cement or lime for the manufacturing of mortar or concrete. It is also used as fillers in mortar and concrete.

What is the purpose of a Sieve test?

Used in conjunction with other tests, the sieve analysis is a very good quality control and quality acceptance tool. Objective To determine the particle size distribution of the coarse and fine aggregates.

How to measure the accuracy of a sieve?

Apparatus  A set of IS Sieves  Balance or scale with an accuracy to measure 0.1 percent of the weight of the test sample.  Mechanical sieve shaker (Optional) Materials  Coarse aggregate  Fine aggregate Procedure 3. 3 1. The test sample is dried to a constant weight at a temperature of (110 ± 5°C) and weighed.

How to determine particle size of fine aggregate?
