Partial Replacement Of Fine Aggregate Using Steel Slag

Fine Aggregate: Those particles passing the 9.5 mm (3/8 in.) sieve, almost entirely passing the 4.75 mm (No. 4) sieve, and predominantly retained on the 75 µm (No. 200) sieve are called fine aggregate. For increased workability and for economy as reflected by use of less cement, the fine aggregate should have a rounded shape.

LIGHT WEIGHT AGGREGATE CONCRETE BY USING COCONUT …

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.

(PDF) Utilisation of Waste Plastics as a Partial ...

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.

Aggregates - Portland Cement Association

For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse.

HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

The Natural Coarse Aggregate (NCA), with nominal diameter from 9.5 mm down to 4.75 mm, used in this work is a granite type stone and the natural fine aggregate (NFA), with nominal diameter smaller than 4.75 mm and greater than 150 µm, is a quartz sand.
