Chain Formation of Fine Particle Aggregates
Nature, 1970WHEN particles of colloidal sizes aggregate “chain formation” is frequently observed. An extreme example is the flocculation of magnet particles1, where stearic mechanisms are undoubtedly involved, but a wide range of spherical particles including both liquid sols and aerosols also contain unexpectedly long strings of particles (for example, refs. 2–5).

Study of fine sediments for making lightweight aggregate
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2007The objective of this study was to investigate the recycling of the fine sediments of Shih-Men Reservoir to manufacture lightweight aggregate. By qualitative and quantitative analysis of the fine sediment and sintered aggregate through soil test, X-ray fluorescence, X-ray diffraction and scanning electron microscopy, a strategy of recycling fine ...

Recycled ceramic fine aggregate for masonry mortar production
Proceedings of the Institution of Civil Engineers - Construction Materials, 2017Construction and demolition waste is composed of fragments of ceramic tiles, steel, wood, plaster, glass, concrete and mortar. Reduction and reuse of this waste can minimise the consumption of natural resources and energy in the construction industry. In addition, high population growth followed by a large housing deficit in many countries highlights ...

Effects of fines content on packing density of fine aggregate in concrete
Construction and Building Materials, 2014Abstract The fines content (particles finer than 75 μm) in aggregate has substantial effects on the performance of concrete. Since the fines content has large surface area that would increase the water demand, maximum limits are often imposed. However, the fines content would also fill into the voids between larger particles to increase the packing ...

Use of Fine Rubber Particles as Fine Concrete Aggregates in Actively Confined Concrete
Key Engineering Materials, 2017This study presents the results of the experimental study on the axial compressive behavior of the rubberized concrete under active confinement. Two different mixes of concretes with rubber replacement ratios of 0%, as a control mix, and 18% were prepared. The effects of the incorporation of rubber and the confining pressure on the compressive behavior

Nature of Fines Produced in Aggregate Processing
Journal of Cold Regions Engineering, 1987The fines produced in a three part laboratory test series developed to simulate crushing, handling, and placement of roadway aggregates were compared to fines determined from field records for six aggregate sources in Alaska. These sources were associated with projects that had final fines contents in the roadway structure which exceeded the amount ...

Fine-Aggregate Angularity: Automated Image Analysis Approach
Transportation Research Record: Journal of the Transportation Research Board, 2000Angularity is one of the important aggregate properties contributing to the permanent deformation resistance of asphalt mixtures. Therefore, methods that are able to rapidly and accurately describe aggregate angularity are valuable in the design process of asphalt mixtures.

Recycling of PET bottles as fine aggregate in concrete
Waste Management, 2010An attempt to substitute in concrete the 5% by weight of fine aggregate (natural sand) with an equal weight of PET aggregates manufactured from the waste un-washed PET bottles (WPET), is presented. The WPET particles possessed a granulometry similar to that of the substituted sand.

Concrete with fine recycled aggregates: a review
European Journal of Environmental and Civil Engineering, 2013This paper presents a review of the literature published so far on the use of fine aggregates from construction demolition waste used as a partial or total replacement of fine natural aggregates in concrete production. The review presents the initial works on this subject and an overview of the existing regulations.

In this work, the effect of gradation of aggregates of size 4.75 mm and below on the rutting response of asphalt mix is studied (while all other parameters are held constant). Four different gradations of fine aggregate are used. These gradations are identified as FA0, FA1, FA2, and FA3.
