The use of recycled aggregates minimizes the density of concrete, owing to the reduced density of the recycled aggregates compared with conventional aggregates. Hu et al. ( Hu et al., 2019 ) stated a reduction in the density of RA used concrete by 4–8% (varying from 2165-2432 kg/m 3 ) compared to the reference concrete containing natural ...

The slump test is the common and practical workability test for fresh concrete and is performed in accordance with ASTM C143 [17]. Fig. 1 shows the slump values for HPCs that are prepared with natural aggregate (b) and RA (c). The maximum detected slump value of HPC without RA was 185 mm [18].Previous studies, however, had …
Conclusion: Recycled Aggregate is the Clear Winner! Choosing between recycled and natural aggregate is more than a construction decision; it's a statement on sustainability. While natural aggregate has its merits and may be preferable in specific contexts, the overarching benefits of recycled aggregate make it a clear frontrunner for those ...
Recycled aggregates are the product of processing inert construction and demolition waste, asphalt planings and used railway ballasts into construction aggregates. Just as primary aggregates, these materials conform to European aggregate standards and national specifications, and make a key contribution to total aggregates demand.
The aggregates were mixed with 7–11 per cent Portland cement and water and then compacted. Compressive/tensile strength, modulus of elasticity, and drying …

Whilst recycled aggregate costs a fraction of the price of raw materials, no sace is made to its quality and performance. On its own, it appears to be just as strong as traditional aggregate and has a reliable structure. However, when mixed with concrete or cement, recycled aggregates are exceptionally durable and have a long lifespan. 3.
The present paper discusses the usage of recycled aggregates (RAs) from CDW, in correlation with natural aggregates (NA) in the manufacture of concrete, both from quality and environmental perspectives. Upon analysis of the physical–chemical and mechanical properties, a replacement ratio of RAs of 50% was suggested, considering …

SQL Aggregate Functions. An aggregate function is a function that performs a calculation on a set of values, and returns a single value. Aggregate functions are often used with the GROUP BY clause of the SELECT statement. The GROUP BY clause splits the result-set into groups of values and the aggregate function can be used to return a single value …
