Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates. Following are the classification of aggregates based on size: Aggregates are classified into 2 types according to size. Fine aggregate; Coarse aggregate; Fine Aggregate. When the aggregate ...

Different Types of Aggregate Types of Concrete Each

When it comes to differentiating the different types of aggregate this is primarily done on the basis of grain size and there are 2 main grain grading sizes: Fine Aggregate: Grain sizes range from 0.15mm up to 5mm e.g. they easily pass through a sieve of 4.75mm but collect on a sieve of 0.15mm. A good example of a fine aggregate is sand (more ...

During sample preparation, the aggregate size distribution of portions obtained after splitting could vary, or the repeated analysis of a sample may reveal different aggregate size distributions, eg due to the irregular shape of aggregates. Such chance variations can be described with appropriate statistical models. By using models to establish measures for the variation, the overall variation ...

The maximum size of coarse aggregate that can be used in a mix depends on the size, shape, and reinforcing of a member, based on these "not-to-exceed" guidelines (see Photos 5 and 6): 3/4 of the clear spacing between rebar or between rebar and forms (cover distance) 1/3 the depth of the slab. 1/5 the narrowest dimension of a member. Often aggregates are analyzed using combined grading of fine ...
