Production Of Artificial Aggregates

Production of artificial aggregates from steel-making slag ...

González-Corrochano et al. manufactured artificial lightweight aggregates by sintering washing aggregate sludge, fly ash and motor oil at 1150 °C. The produced aggregates obtained the strength of about 8 MPa with the corresponding water absorption of 14–17% (zone 3- Fig. 7 a).

Artificial Aggregate - an overview | ScienceDirect Topics

5.2.4 Artificial Aggregate Production. The production of artificial aggregate generally aims to manufacture a material with a strong surface layer and good structural performance, though also with higher porosity and associated lightweight characteristics. These aggregates can be suitable for use in lightweight concrete and a growing number of other possible applications including lightweight …

production of artificial aggregates

Artificial manufactured lightweight aggregates can be produced from industrial by-products such as fly ash, bottom ash, silica fume, blast furnace slag, rice husk,...

Artificial Aggregate Production from Fly Ash

Manufactured Lightweight Aggregates c,d,e. Produced from natural materials. Most of these thermally processed lightweight aggregates are produced from materials such as clay, shale or slate. To produce such aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material.

Lecture 4. Aggregates - Aalto

• Artificial aggregates are made out of various waste materials. • Artificial aggregates are sometimes produced for special purposes: - for making lightweight concrete: burned clays, artificial cinders, foamed slag, expanded shales and slate, sintered fly ash exfoliated vermiculite are used - for making heavy- weight concrete: steel rivet

Construction aggregate - Wikipedia

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as …

SOLUTION: The suitable blending ratio of the construction sludge to the expandable shale is 2-100 pts.wt. construction sludge to 100 pts.wt ...

Concrete - Wikipedia

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.
