Aggregate Durability & Abrasion Test Equipment
Choose the Degradation Test for the Material
Aggregate durability testing measures resistance to degradation, abrasion and weathering. The Los Angeles abrasion test, Micro-Deval test, sulfate soundness test, durability index and slake durability test each answer a different question about the material. Select equipment by the governing procedure, sample gradation and required documentation rather than treating all durability equipment as one interchangeable group.
Laboratory durability results are one input to material selection and specification compliance. Confirm the required test methods for your project before purchasing, and do not substitute one degradation test for another without checking the governing specification.
Compare Los Angeles Abrasion Machines
The Los Angeles (LA) Abrasion Machine is a rotating-drum machine with an abrasive steel-ball charge. Multiple LA machine configurations are listed, including units with safety cabinets and soundproofing. Compare drum specifications, speed control, safety interlocks, sound enclosure and electrical supply rather than assuming all LA machines share one configuration.
Check what each machine includes: the referenced listing includes a catch pan and a twelve-ball abrasive charge, but charge quantity, shelf style and cabinet options vary. Accessories such as the Catch Pan for Los Angeles Abrasion Machine, replacement charge balls and steel shelves should be matched to the selected machine. Follow the manufacturer's installation, ventilation and noise-control guidance; an enclosure does not replace the laboratory's noise assessment.
Specify Micro-Deval and Soundness Equipment
The Micro-Deval Apparatus uses sealed stainless-steel jars with an abrasive charge and water. Confirm jar quantity and capacity, electronic controls, safety interlocks and included abrasive charge sets. Replacement 5L jars with locking covers, abrasive charges and a charge retrieval magnet are listed separately; verify compatibility with your apparatus before ordering replacements.
For sulfate soundness testing, compare the Water Bath Tank for Sulfate Soundness Testing, Sulfate Soundness Washing Tank and the listed sodium and magnesium sulfate hydrometers. Confirm solution preparation, immersion and drying requirements, including any required drying oven, rather than assuming one tank or hydrometer serves both sulfate types.
Include Durability Index and Slake Durability Apparatus
The Durability Index Agitator and its washing vessel support durability index procedures. For shale and weak rock, the Slake Durability Apparatus rotates wire-mesh drums through wetting and drying cycles; additional wire mesh drums, tank and drum assemblies and water tanks are listed separately.
Confirm drum quantity, tank count and base capacity for the selected slake configuration, along with the required oven-drying arrangement between cycles. Verify electrical supply and installation space for each motorized unit before ordering.
Match Accessories and Confirm the Complete Order
Check sieves, balances, drying ovens and sample-preparation equipment required by the governing method; these are separate purchases from the durability apparatus itself. Follow the manufacturer's instructions for operation, cleaning and maintenance, and use the specified safety equipment when handling drums, jars and chemical solutions.
Keep each test method's equipment separate: an LA abrasion machine, a Micro-Deval apparatus and a soundness bath are not interchangeable. Where degradation results feed into other aggregate testing, coordinate sample preparation using aggregate sample splitters and dividers rather than substituting durability apparatus for preparation equipment.
