Constituent materials of concrete 174 fine aggregates are generally natural sand or crushed stone, with most particles passing through a 38 inch 9.5 mm sieve. coarse aggregates generally range between 38 to 1 12 inches 9.5 mm to 37.5 mm in diameter. most coarse aggregate used in concrete is.
Fine crushed stone aggregates consist of particle sizes that are typically less than 38-inch 9 mm. Fine aggregates are used in asphalt, concrete, backfill, construction and specialty applications. Common Uses Concrete Asphalt Backfill and bedding materials Skid resistance on ice or snow Agricultural-lime Ag-lime.
Crushed stone is exactly what it sounds like, rocks that have been crushed or broken down by crushing machines. Its main uses are as an aggregate for construction and landscaping purposes. Crushed stone and gravel are different in that natural processes produce gravel and its surface is rounded as opposed to the more angular surfaces of crushed stone.
Granite Rock Fines are crushed granite. This material is 14quot Minus and well graded to provide for excellent compaction and contains no large aggregate. Uses include compacted base under pavers, as track fines, path fines, and athletic infield material. Granite Rock Fines are produced daily and stored in a covered bin so they are available dry year round. This aggregate is typically gray in color.
Crushed Stone Grades. The following list gives a rundown of crushed stone grades and their best uses. While there may be slight variances in the naming convention of crushed stone the following are the most common names and sizes Crushed stone 5 Sizes are from 1 down to fine particles. For road and paver base.
The economic gain of replacing sand with Crushed Granite Fines in the production of concrete was investigated. Compressive strength and slump tests were performed on fresh and hardened concrete using two nominal mixes of 112 and 11189 3 with the sand component being partially replaced with Crushed Granite Fines. Compressive strength values above 30 Nmm178 and 35 Nmm178 were obtained.
The properties of the aggregate were also compared. The fine aggregate for recycled and conventional concrete was 100 percent natural sand. Two sources of recycled aggregate crushed concrete pavements from U.S. 23 and 1-75 projects in Michigan and one source of natural aggregate crushed limestone were used. Two maximum sizes of aggregates.

Coarse Aggregate. Crushed stone is created through the mining and crushing of rock. The rock is crushed into several different graded sizes for use in applications including ready mix concrete, asphalt and decorative stone. Gravel is created by river erosion, resulting in smooth and rounded products.
2015-12-4 use of machine crushed granite stone fine aggregate from here after known as crushed stone fine aggregate which is a by-product obtained from the granite machine crushing industries in the production of granite as coarse aggregate in different specific required sies is considered as an alternative material to river sand in concrete.
The use of only Makurdi river sand as fine aggregate and gravel to produce grade C 35 concrete will cost N 16,559 a value lower than N 16,580 and N 16,622 obtained with the use of Makurdi river sand partially replaced with 10 and 30 crushed granite fine respectively.

May 05, 2011018332I was advised from the field that the 610 in the area is crushed granite, not limestone as in the dwg notes, so they want to know how to proceed. Granite is a harder rock, so I was thinking no issue, but Im wondering if permeability bathtub effect is a big difference when comparing granite fines vs limestone fines.
The fine and coarse aggregates generally occupy 60 to 75 of the concrete volume 70 to 85 by mass and strongly influ-ence the concretes freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates Fig. 5-1 generally consist of natural sand or crushed stone with most particles smaller than 5 mm 0.2 in.
May 15, 2016018332The influence of crushed granite fine aggregate CGA on the rheological and mechanical properties of concrete is reported in this work. Concretes were produced with 10, 30, and 50 in volume of fine aggregates of CGA, with respect to a reference mixture, which contained a regular siliceous river sand.
