Raw materials that are a component in concrete, aggregates are inert granular materials such as sand, gravel or crushed stone. Coarse aggregates are particles greater than 4.75mm, but they generally range between 9.5mm to 37.5mm in diameter. Primary coarse aggregates come from the land or water. Secondary aggregates are the by-products of extractive operations. The third source coarse aggregates come from is recycled aggregate, which is sand, and recycled concrete aggregate.

what would be the effect upon the unit weight of the fine and coarse aggregates be combined
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 the diameter of coarse aggregates that used to strip foundation?
20mm
Which materials are considered inactive ingredients in concrete?

What is composition of plain cement concrete?
Plain cement concrete is primarily composed of three key materials: cement, aggregates, and water. The cement acts as a binding agent, while aggregates, which include fine aggregates (like sand) and coarse aggregates (like gravel or crushed stone), provide bulk and strength. The water facilitates the chemical reaction that allows the cement to harden and bind the aggregates together. Typically, the mix ratio can vary, but a common formulation is 1 part cement, 2 parts sand, and 4 parts coarse aggregates by volume.
What is the cement content for M7.5 grade concrete?
For M7.5 concrete, the common mix ratio is 1:4:8. This means:1 part cement 4 parts fine aggregates (sand)8 parts coarse aggregates. These ratio is by volume.
Why suitable coarse and fine aggregate used in the concrete ingredient?
aggregates are used to concrete for following purposes: 1.if totally binding materials like cement is used in concrete, the cost of concrete will be high which is uneconomical. 2.to prevent high shrinkage of concrete mix fine aggregates are used. 3.to increase the volume of concrete mix aggregates are used.
How coarse aggregate shape affect workability?
Aggregates with angular particles are more difficulties to compact than one with rounded particles and therefor,requires more water in the mix to act as alubricant.this additional water, on evaporation ,tends to leave void spaces in the hardened concrete made with rounded aggregates particles which requires less water for compaction.the nature of the particles of an aggregates will also affect workability.(
Why it is not suitable for all concrete mixture when the amount of fine aggregate and coarse aggregate is fixed in sieve test?
Why it is not suitable for all concrete mixture when the amount of fine aggregate and coarse aggregate is fixed?
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.
