Quality Control Sieve 19mm Astm

The ASTM 19.0 mm sieve (3⁄4 inch sieve) is a standard coarse sieve used for grading aggregates in accordance with ASTM International under ASTM E11 specifications. It has a 19.0 mm square opening and is primarily used to separate coarse aggregate particles in concrete, asphalt, and road base materials. This sieve is essential in aggregate gradation tests to determine the maximum aggregate size and ensure compliance with construction standards. It helps assess material suitability for structural concrete and pavement layers. Manufactured with a strong stainless-steel or brass frame and heavy-duty woven wire mesh, the ASTM 19.0 mm sieve ensures durability, accuracy, and reliable laboratory performance.
