Test Sieve for Coarse Aggregate

Test sieves are essential tools in the construction and mining industries for analyzing the particle size distribution of coarse aggregates, such as gravel, crushed stone, and other granular materials used in concrete, asphalt, and road base applications. Coarse aggregates typically range in size from 4.75 mm to 100 mm, and their size distribution significantly impacts the strength, durability, and workability of construction materials. Test sieves provide a reliable and standardized method for ensuring that coarse aggregates meet specified grading requirements, which are critical for achieving optimal performance in engineering projects.
