Aggregates And Their Properties In Concrete Presentation Mark Learn about the functions and properties of concrete aggregates, factors affecting concrete mixtures, types of aggregates, and important testing procedures in this comprehensive guide. The document outlines the classification and properties of aggregates used in concrete and mortar, including natural and artificial types, as well as size classifications such as coarse and fine aggregates.
Aggregates Pdf Concrete Construction Aggregate Aggregates.ppt free download as powerpoint presentation (.ppt), pdf file (.pdf), text file (.txt) or view presentation slides online. this document discusses different types of aggregates used in concrete, including their classification, properties, and common tests. Lightweight aggregates are more fire resistance than normal weight aggregates due to their insulation properties. concrete containing calcareous coarse aggregates performs better under fire exposure than siliceous aggregate (granite or quartz). Lightweight expanded clay, shale or slate, crushed brick used primarily for making lightweight concrete for structures, also used for its insulating properties (1350 to 1850 kg m3). Aggregate is a term for any particulate material. it includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. aggregate may be natural, manufactured or recycled. aggregates make up some 60 80% of the concrete mix.

The discussion in this module will begin with the geology of aggregates. we will then cover the classification and characteristics of aggregates, followed by potentially harmful materials. some time will be devoted to discussing alkali aggregate reactivity and then we will wrap up with beneficiation, handling, and storage of aggregates. Angular aggregates produce bulk materials with higher stability than rounded aggregates. flakiness describes the relationship between the smallest and largest dimension. roughness of aggregate surface plays an important role in the way aggregate compacts and bonds with the binder material. Aggregates are cost effective and stable fillers for concrete. The surface characteristics of aggregate affects the workability of fresh mass & the bond between the aggregate & cement paste in hardened concrete. if it is rough, workability decreases & bond increases.
