How do you measure the average size of fine aggregate and coarse aggregate?
The average size of fine aggregate is typically measured using a sieve analysis, where the aggregate is passed through a series of sieves with different mesh sizes to determine the distribution of particle sizes. For coarse aggregate, a similar sieve analysis is conducted, but it often involves larger mesh sizes. The average size can be calculated by determining the weight of aggregate retained on each sieve and then using these weights to find a weighted average particle size. Additionally, tools like the geometric mean can also be employed for more precise measurements.
How coarse aggregate can be classified as per IS?
as we know we have sieve sizes. aggregates which got retained in 4.75 mm sieve size is known as coarse aggregates or we can say aggregates having size more than 4.75mm.
What is sieve size?
It refers to the go / no go boundry, a 5 mm sieve wont let anything larger than 5 mm through, but anything less will pass through.
What is blaine of cement?
ANSWER In simple terms, the "blaine" is a measure of the particle size or fineness of cement.
What is calculated load?
A calculated load in electrical terminology is the sum of all of the loads that are connected to a system. To size a service distribution for a home all of the connected loads have to be calculated in. Some loads can be derated as per the electrical code. When the total amperage is calculated from the sum of all of the loads, the wire size and distribution can be sized to handle the calculated load.
What is sieve analysis?
Sieve analysis is carried out to estimate particle size distribution in a given feed material. Sieve types normally designated by Tylor mesh series.
What are the key steps involved in conducting the three sieve test for particle size analysis?
The key steps in conducting the three sieve test for particle size analysis are: Selecting three sieves with different mesh sizes Weighing a sample of the material to be tested Passing the sample through the sieves and collecting the particles retained on each sieve Weighing the particles retained on each sieve Calculating the percentage of material retained on each sieve Plotting a particle size distribution curve based on the results
What do you mean by sieve no10?
"Sieve no.10" usually refers to a specific mesh size in a sieve analysis used to determine the particle size distribution of a sample. In this case, "no.10" typically corresponds to a sieve opening of 2.00 mm. The sieve analysis helps in characterizing the size of particles in a material sample.
What are the applications of sieve analysis?
A sieve analysis test is a procedure to separate fine material from course material by means of a series of woven or perforated surfaces. The proportion of different size particles are recorded. This record is the conclusion of the analysis. Art Gatenby agatenby@cscscientific.com
What range of particle size does the sieve analysis apply?
· The ranges of the sieve analysis applies between 75mm (3in.) and No.200 (75Mm) sieves.
What is the conclusion of sieve analysis?
The conclusion of a sieve analysis is to determine the particle size distribution of a sample. This is achieved by passing the sample through a series of sieves with decreasing mesh sizes to separate and weigh the particles in different size fractions. The data collected from this analysis can be used to determine the uniformity of the sample and its suitability for various engineering applications.
What is sieve shaker used for?
A sieve shaker is used to apply mechanical vibrations to a stack of sieves to help separate particles based on size. This process is commonly used in soil analysis, aggregate testing, and other particle size distribution studies in various industries like pharmaceuticals, food processing, and construction.

What is the significance of the z-average in particle size analysis?
The z-average in particle size analysis is significant because it provides a more accurate representation of the particle size distribution compared to other averages. It takes into account the intensity of scattered light from particles, giving a weighted average that is less influenced by larger particles. This helps in understanding the overall size distribution of particles in a sample.
How is a sieve used in earth science investigations?
In Earth science investigations, a sieve is used to separate soil or sediment samples by particle size. By passing the sample through different sized mesh screens, researchers can analyze the distribution of particles and classify the sample according to granular size fractions. This helps in studying soil composition, sediment transport, and understanding geological processes.
Fineness test for gypsum?
The traditional way of testing gypsum for fineness involves rubbing up with turpentine
What is the importance of sieve analysis?
The preparation or introduction of Sieve Analysis a sample of the aggregate must be obtained from the source. The aggregate, the total weight is required. it should be mixed thoroughly and then reduced to a suitable size for testing in order to prepare the sample.
