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 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 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.

How does the porosity vary with the amount of clay in the soil?

The voids present between the soil particles are called pore space and the size of these pores depends on whether the ore is between the soil particles or between the soil aggregates. In general, in cultivated lands, soil particles do not exist as single grains and therefore, there are only voids within the soil aggregates or peds and voids between the aggregates. As clay particles play a major role in the formation of soil aggregates by way of binding the soil particles, the particles within the aggregates are micro pores and between the aggregates are macro pores. Depending on the amount of clay particles, the proportion of micro to macro pores may vary and in most cases the soils containing more clay particles favour aggregation and thereby the micro pores and total porosity.


Difference between estimate estimator?

I think, the estimate is a numerical value, wile the estimator is a function or operator, which can be generate more estimates according to some factors. For example (xbar) is estimator for (meu), which can be various when the sample size in various, the value that will be produced is an (estimate), but (xbar) is estimator.
