Coarse Aggregate Angularity Apparatus

General Features:
Coarse Aggregate Angularity Apparatus measures the uncompacted void content of coarse aggregate. The testing apparatus is recommended to evaluate aggregates for Hot-Mix Asphalt (HMA) pavement. Gradation and void content data provide an indication of angularity, sphericity, and surface texture that can be related to permanent deformation and fatigue cracking of asphalt.
Aggregate is allowed to free fall from the hopper into a cylindrical measure. Excess heaped aggregate is struck off using the included bar, the mass is measured, and void content is computed. The hopper, stand, and measure is stainless steel and a locator pin and circle on the bottom plate of the stand make it easy to center the measure below the hopper.
Coarse Aggregate Angularity Apparatus consist of Stainless Steel Measure, Strike-off Bar and Glass Plate for calibration.

Steel Material Handling Pan should be ordered separately.

Specific Gravity Frame (Bouyancy Balance System)

General Features:

Used in conjunction with a suitable electronic balance for specific gravity determination of fresh and hardened concrete and aggregates. To be used with a suitable electronic balance fitted with an under –hook facility. The lower part of the frame incorporates a moving platform, which carries the water tank allowing the test specimens to be weighed in both air and water. The balance is not included in the test set and must be ordered separately. Any type of electronic balance fitted with under-bench weighing facility can be used.

Abrasion Tester For Natural Stones And Concrete

General Features:
Abrasion Tester used to determine the resistance to abrasion and wear of natural stones and concrete products by measuring the length of a groove produced on the specimen surface by disc with thickness of 70 mm that rotates at controlled speed and makes a constant pressure on the specimen. A charge of abrasive material must be interposed between the disc and the specimen. The abrasion wheel rotates at a speed of 75 rpm. The machine is equipped with digital counter which stops machine at the preset number of revolutions.

The abrasive corundum sand and calibration (Boulonnaise) marble are optional.

Moisture Meter Microlance

General Features:
This electronic tester measures and visualizes directly on the display the moisture percentage and temperature of sands, aggregates, building materials, minerals and mixes up to max. dia of 10 mm by simply inserting the crucible tip. For quick, convenient, on-site moisture measurement from small batches to hundreds of tons. Instant spot read out or average of whole load.
No sample preparation, chemicals, balances or ovens etc.
