This paper presents the results of a study to compare the properties of concretes prepared with the use river sand, crushed fine stone (CFS), furnace bottom ash (FBA), and fine recycled aggregate (FRA) as fine aggregates. Two methods were used to design the concrete mixes: (i) fixed water–cement ratio (W/C) and (ii) fixed slump ranges.
2020-4-12 Properties Of Fine Aggregates: There are several properties of the fine aggregates as given below: Size: The size should be equal to or less than 4.75mm. Shape: To completely round grained sand, the sand of irregular nodular shape is preferable and in coarse aggregates shape of aggregate plays an important role. Specific Gravity:
1989-7-1 The mixes of each series incorporated different percentages of very fine sand (VFS) as a replacement for fine aggregate. Results indicate that the water demand increases rapidly when the VFS replacement is more than 5 percent in natural sand concrete and more than 15 percent in crushed stone sand concrete.
2019-11-11 Crushed stone often has an angular and jagged edge that occurs during the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to the effects of running water.
2020-7-27 Generally, as the grade number goes up, the size of the stone goes down. #1 The # 1 crushed stone grade is the largest of the crushed stone grades and includes stone between 2-4 inches long. This material is great for larger jobs or for filling in larger holes. #3 This size of the stone ranges from 1/2 to 2 inches long.
