Why should aggregates be well graded?
Aggregates must be well graded in order not to have a gap that may cause a weak point and that is necessary for : 1-Asphalt mixes 2-concrete mixes 3-Road material.
How to top up damage floor screed?
Damage floor screeding can be topped up by applying a well blended mixture of Cement with graded aggregates and water to the floor base.
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.
Why fineness modulus of coarse aggregates is more than that of fine aggregates?
how does the fineness modulus of aggregate affect the strength of concrete
Why should aggregates be well graded?

Do Well graded aggregate allow concrete to use more or less water?
well-graded aggregates need less water.
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.
How to top up damage floor screed?
Damage floor screeding can be topped up by applying a well blended mixture of Cement with graded aggregates and water to the floor base.
How does the deleterious material affect the properties of aggregates?
Deleterious material in aggregates can weaken the overall strength of the material, reduce durability, and increase the potential for deterioration due to chemical reactions or expansion. It can lead to poor bond between aggregates and the binder, causing issues such as cracking and reduced load-bearing capacity in concrete or asphalt mixes.

How are us coins graded?
US coins are usually graded on the Sheldon scale. The Sheldon scale grades coins from 1-70. A coin graded 1 is very, very, poor and is basically only identifyable by the size of the coin. A coin graded 70 is perfect with no defects at all. Most coins grade somewhere in between the two extremes.
What ASTM coves the sampling of aggregates?
ASTM D75 is the ASTM that covers the sampling of aggregates.
What is coarse aggregates?
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.
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.
