GRADATION OF AGGREGATE FOR CONCRETE BLOCK
the most costly ingredient in the concrete mix, the selection of a properly graded aggregate assumes an economic aspect. 2. Texture—The surface texture of the finished block depends to a great extent upon the gradation of the aggregate. Coarse grading tends to produce rough or coarse textured block, while fine gradations generally yield block ...

Grading of aggregate in a concrete mix is necessary to ...
2020-6-20 4 answers. Aggregate occupies most of the volume of the concrete. The composition, shape, and size of the aggregate all have a significant impact on the workability, durability, strength, weight, and shrinkage of the concrete. Hence, the gradation of aggregate in concrete becomes an essential part. This means that the particles pack together ...

2021-11-22 For a mix to be satisfactorily workable, it must contain a sufficient amount of material smaller than 300 micron size including cement particles. Thus a richer mix requires a lower content of fine aggregate than a lean mix. If the grading of fine aggregate (sand) is such that it is deficient in finer particles, in that case increase in fine ...

2016-5-25 The nominal mixes of fixed cement-aggregate ratio (by volume) vary widely in strength and may result in under- or over-rich mixes. For this reason, the minimum compressive strength has been included in many specifications. These mixes are termed standard mixes. Here the structural Engineer prescribes a standard concrete mix ratio that he thinks ...
