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 much sand and aggregate required 1 cubic meter of plain concrete cement?
For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm
IS codes for fine aggregate coarse aggregate cement?
fine aggregate zone classification codes
What is particle size distribution in sieve analysis?
Distribution of soil particles for identifying the type of soils ie., wherther it is well graded or uniform graded or poorly graded soil.And also fine sand, medium sand coarse sand or fine gravel, medium gravel, coarse gravel etc.
How to improve the workability of concrete?
To improve the workability of concrete, issue to be concerned of as below: - increase water/cement ratio - increase size of aggregate - use well-rounded and smooth aggregate instead of irregular shape - increase the mixing time - increase the mixing temperature - use non-porous and saturated aggregate - with addition of air-entraining mixtures
Does sizes of aggregates affect the compressive strength of concrete?
Larger the size of aggregate will decrease strength of the concrete because surface area of this aggregate is low.Lesser the size of the aggregate will lead to increase the strength of the concrete.Well graded aggregate have all size of particles hence particle interferance is neglected,thus strength of concrete is more.
What mean by nominal size of aggregate?
Nominal size is the size of the largest aggregate in a grading.
Do Well graded aggregate allow concrete to use more or less water?
well-graded aggregates need less water.
How much does a cubic yard of graded aggregate base weigh?
2.2 Tons
What is aggregate size?

What size is coarse aggregate?
20 mm thick coarse aggregate use in slab cast
Are graded deposits sorted deposits?
Graded deposits have been sorted by size, usually by deposition from moving water.
What is the meaning of agrego?
agregar v. add; aggregate; incorporate; tack on
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 the different types of aggregates?

Why should the cement aggregate be well graded?
A variation in aggregate side (well graded) allows the concrete to be more dense, which means less voids, which allows for stronger concrete. Think of it this way. If you had a two rooms, and you filled one with just basketballs and the other with beach balls, then basket balls, then baseballs, then golf balls, then bee bees which would you think would be filled more. The one with the varying sized balls.
What is it called when sediments are layered and sorted by size?
It is called graded bedding.
