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.

Jan 02, 1992  15.3.4.1 Design of Processing Plants. 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 ...

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 ...

The effect of the different aggregate roughness (Fig. 3.10) in a small-size beam (80×320 mm 2) of gravel concrete (d 50 = 2 mm and d max = 8 mm) is shown in Figs 3.11–3.14 (ρ = 30% and ρ = 45%, l c = 1.5 mm, t b = 0.25 mm).The results with the different aggregate roughness are compared using the same stochastic distribution.

The aggregates that are used for conventional concrete can normally be used with epoxy-resin mixtures. All aggregates should be clean and dry when repairs are made. Maximum size for aggregates used in an epoxy-based concrete is 1 inch in diameter. The proportion of aggregate to the mixed resin in epoxy concrete can go as high as a 12-to-1 ratio.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...
