Aggregate test is a process of performing certain tests on aggregates, as it is one of the main components of concrete. it is necessary to have certain checks for the physical properties, quality, and suitability of aggregates for specific applications in construction projects. Different types of Aggregate tests are conducted in the laboratory and field based on project …
Types of Aggregates. Elongated aggregates: length > 180% of mean dimension, poor interlocking behavior, weak bond strength; Flaky aggregates: thickness < 60% of mean dimension, poor interlocking behavior, weak bond strength; Irregular aggregates: partially rounded, result in 35-37% voids, lesser workability, slightly higher bond strength
In addition, the processing of small fraction aggregates is time consuming in the laboratory, and is usually difficult to perform in the field. The encapsulation of the aggregates is made by cement slurry, with a (W/C) ratio of 0.5 [53]. ... The four types of crushed aggregates were subjected to thermogravimetric analysis (TGA), between 20 °C ...
