Importance Of Size Of Coarse Aggregate

Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm. Fine aggregates contain particles in the size range 75 m to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for

importance of size of coarse aggregate

The most important consideration in selecting the largest aggregate size in a concrete mix is: coarse aggregates are retained on #4 sieve size, they occupy more weight and volume in concrete mixes, and provide resistence to abrasion.

Effect of Size of Coarse Aggregate on Mechanical

Experimental studies were conducted to explore the effect of the size of the coarse aggregate on the mechanical properties and microstructure of a metakaolin-based geopolymer (MKGP) concrete and ordinary concrete. Three coarse aggregate size grades (5–10 mm, 10–16 mm, and 16–20 mm) were adopted to prepare the specimens.

Geopolymer binders are a promising alternative to ordinary Portland cement (OPC) because they can significantly reduce CO2 emissions. However, to apply geopolymer in concrete, it is critical to understand the compatibility between the coarse aggregate and the geopolymer binder.

Coarse aggregates are classified into two main groups: (i) single-size aggregate and (ii) graded aggregate. Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve.
