Micro-Deval Test for Aggregate Abrasion by ScribdTranslations is a document available to read on EtoBox.
The Micro-Deval test determines the abrasion resistance of coarse aggregates subjected to the combined action of abrasion and grinding with steel balls in the presence of water. A representative sample of 1500 ± 5 g is prepared, which is placed in a container with water and 5000 g of steel balls for 2 hours at 100 rpm. The sample is then sieved, and the abrasion loss is calculated as the percentage of material smaller than 1.18 mm. The test provides information about the durability of the aggregate.
