What are the different types of aggregates?
There are two different types of aggregates namely,Fine aggregates - size of the aggregate is less than 4.75 mmExample : SandCoarse aggregates - Size of the aggregate is more than 4.75 mmExample : Gravel
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 factors affect the workability of a concrete mix?
1),water content 2),mix praportions 3),size of aggregates 4),shape of aggregate 5),surface texture 6),grading of aggregates 7),use of admixture
What is poor graded aggregates?
Poor graded aggregates refer to a mix of aggregate particles that lacks a well-defined distribution of sizes, resulting in an uneven particle size distribution. This can lead to a higher percentage of voids, reduced density, and increased water demand in concrete or asphalt mixes. Poorly graded aggregates may negatively impact the strength and durability of the final product, making them less desirable for construction applications. Effective grading is essential for optimizing the performance of concrete and ensuring longevity.
What is the maximum size of aggregate allowed in concrete to be tested for air content by pressure method?
The maximum size of aggregate allowed in concrete for testing air content by the pressure method is typically 1 inch (25 mm). This limit ensures that the test accurately measures the air content without interference from larger aggregate particles. For aggregates larger than this size, alternative testing methods may be required.

What is mean by good grading?
The word "grading" refers to the diversity in size of the aggregates. Aggregates that have "good grading" or are "well graded" have the same % of each size stone. The goal is to get the maximum aggregate packing density within a mix that still allows the cement to bond to the aggregates and cure properly, since its the aggregates that give concrete its high compressive strength.
What are clumps of small particles?
Clumps of small particles are referred to as aggregates, which are collections of individual particles that have come together due to various forces such as gravity, electrostatic attraction, or molecular adhesion. These aggregates can vary in size and shape depending on the properties of the particles and the forces involved in their formation.
What is fine aggregate?
Fine aggregates are the aggregates whose size is less than 4.75 mm.Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar.
What is maximum and minimum size of aggregates used in rhe rapid chloride permeability test?
The maximum size of aggregates typically used in the rapid chloride permeability test is 19 mm (3/4 inch), while the minimum size is 9.5 mm (3/8 inch). These sizes are recommended to ensure proper testing conditions and accuracy of results.

What are the medium sized lumps of a substance called?
The medium-sized lumps of a substance are called granules. Granules are intermediate in size between powder and larger aggregates or chunks.
What is AASHTO Method T27?
AASHTO Method T27, also known as "Standard Method of Test for Sieve Analysis of Fine and Coarse Aggregates," is a standard test method used for determining the particle size distribution of aggregates. This method involves sieving the sample through a series of sieves and calculating the percentage of material retained on each sieve to classify the aggregate. It is widely used in the construction industry to ensure the quality and gradation of aggregates for use in concrete and asphalt mixtures.
