The compressive strength of concrete mixtures having different types of coarse aggregates was determined following ASTM C39:2018 [51]. Similarly, dry density, the volume of permeable pores, and water absorption of RAC specimens incorporating untreated and treated RCA were evaluated as per ASTM C642:2013 [52]. To measure …
Although aggregate is considered inert filler, it is a necessary component that defines the concrete's thermal and elastic properties and dimensional stability. Aggregate is classified as two different types, coarse and fine.
Type of Aggregate: The type of aggregate used in concrete also affects the mix ratio. Different types of aggregate, such as gravel or crushed stone, have different characteristics and can affect the workability, strength, and setting time of the concrete.
In this research work, two types of recycled aggregates were used: (1) the recycled concrete aggregate, RCA, obtained by crushing the parent concrete produced using limestone cement and (2) the recycled concrete aggregate RCA-FA produced by crushing parent concrete made with FA blended cement. After the carbonation treatment …
The mix proportions of different treatment slurries are presented in Table 2. In making slurries, the three different types of strengthening slurries were prepared by blending the strengthening materials with water (twice the weight of RCA) for 2 min.
The different types of aggregates used in road construction are as follows: Fine aggregate Aggregates that have a grain size less than 4.75 mm are called fine aggregates.
