Fine Aggregate: Definition, Size, Density and Properties

2017.11.12  Aggregate is the granular material used to produce concrete or mortar and when the particles of the granular material are so fine that they pass through a 4.75mm sieve, it is called fine aggregate. It is widely used in the construction industry to increase the volume of concrete, thus it is a cost saving material and you should know everything ...

Effect of aggregate properties on asphalt pavement friction

2021.7.19  AIMS angularity, loss of angularity (%) and AIMS texture exhibit secondary contributions to pavement friction, whose importance values are 2.72%, 2.07%, and 2.00%. AIMS angularity is associated with the variations at the corners superimposed on aggregate shapes, which will affect the macro-texture of the pavement surface.

Evaluation of Geometric Characteristics of Fine Aggregate and

It has long been recognized that fine aggregate (FA) plays a crucial role in the performance of asphalt mixture, especially for the viscoelastic behavior. In this research, 13 types of FA (1 natural sand, 5 stone chips, and 7 machine-made sands) were selected for investigation. Three indirect indicators (uncompact void content test, flow time test, and standard test

Influence of fine aggregate's morphology on mortars' rheology

2023.1.1  However, besides an irregular shape, some types of alternative fine aggregate have greater angularity and a rougher surface texture than natural sand [[22], [23], [24]]. A rougher surface texture would lead to higher frictional energy consumption when the fine aggregate particles and suspension move relative to each other, which
