How marine aggregates are extracted. A significant proportion of the demand for aggregates is satisfied from river, lake, and sea beds. Our marine resources are an increasingly important alternative source of aggregates. Marine aggregates play an important role in replenishing beaches and protecting coastlines from erosion.

Fine Aggregate Size Requirement As Per IS 456. If you remember, I have mentioned the size of the fine aggregate as recommended by IS. Let me recall. The aggregates passing through 4.75 mm sieve and retained on 0.15 mm sieve are called fine aggregates. Different size of sand is necessary for different works.

Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design.

In this context, use of recycled fine aggregate (RFA) from construction and demolition (C&D) waste can be considered as an effective elucidation. Conventional mix proportioning of RFA in concrete can not be used. To address this issue, a novel mix-proportioning method is developed using particle packing density and minimum paste theory.
