Aggregate Concrete - an overview ScienceDirect Topics

02/01/1992  The objective of any concrete aggregate processing operation should be the production of good-quality, ‘clean’ coarse and fine materials in the normal range of sizes. The types of equipment used and the flow design of the plant are more or less completely dependent upon the nature and properties of the source raw material.

Concrete Aggregate - an overview ScienceDirect Topics

Concrete Aggregate. RCA contains a percentage of material containing mortar and if this is taken into account when designing a concrete mix, there is a likelihood that equal or better compressive strength can be achieved using RCA when compared to NA.

Pervious Concrete - an overview ScienceDirect Topics

The recycled clay brick aggregate is the weakest and shows the largest fractured surface and is followed in turn by recycled concrete aggregate and normal aggregate. The same authors reported further that the average ratio of splitting tensile to compressive strengths of pervious geopolymer concrete was 14.4%, which was slightly higher than 8–14% for conventional concrete. The high tensile ...

Aggregate Reaction - an overview ScienceDirect Topics

Mark G Alexander, in Developments in the Formulation and Reinforcement of Concrete (Second Edition), 2019. 4.1 Introduction. Alkali– aggregate reaction (AAR) 1 is a chemical reaction between alkalis in the concrete and reactive components of the aggregates. It was first observed in the United States in the 1920s and initially researched by Stanton in 1940. AAR is a type of internal chemical ...

Jorge de Brito, ... José D. Silvestre, in New Trends in Eco-efficient and Recycled Concrete, 2019 11.3.1 Recycled aggregates. As concrete production keeps on increasing worldwide, so does the use and consumption of abiotic resources, such as aggregates. To corroborate this statement, the worldwide aggregates demand will raise from 45.9 to 66.3 Gt in a time span of 10 years (e.g., 2012–22 ...

Fine Aggregate Component - an overview ScienceDirect Topics

As a fine aggregate component in masonry blocks: • It was found that a 10% SSA addition led to an increase in density (2058 to 2204 kg/m 3) and compressive strength (7.0 to 14.4 MPa) and a decrease in absorption (8.7% to 6.0%) (Baeza-Brotons et al., 2014).These results are strikingly inconsistent with the previous findings when SSA was used as a sand replacement in mortar and concrete mixes.
