ABRASION RESISTANCE OF CONCRETE - UNDER WATER METHOD - ASTM C1138

ABRASION RESISTANCE OF CONCRETE - ASTM C1138

Model Number : CA-1311

The underwater abrasion resistance test (ASTM C1138) evaluates the durability of concrete surfaces when exposed to hydraulic forces and suspended abrasive materials, as commonly encountered in hydraulic structures. The test quantifies the abrasion resistance by measuring the mass loss of concrete specimens subjected to a rotating propeller in water containing abrasive particles.

Underwater Method : ASTM C1138

This test method covers a procedure for determining the relative resistance of concrete(including concrete overlays and impergnated concrete) to abrasion under water. This method helps evaluate the durability of concrete in hydraulic structures such as dams, spillways, and canals, ensuring materials meet performance requirements for abrasive conditions.

The equipment consists of the following replaceable parts:

Rotating Device - A motorized paddle or stirring apparatus capable of maintaining a constant rotation speed to ensure uniform abrasion action. A machine with a chuck capable of holding and rotating the agitation paddle under test condition at a speed of 1200 +100rpm.
Agitation Paddle
Test Container-A steel pipe,305 +6mm inside diameter, 450 + 25mm fitted with a watertight steel base is used. A six steel blocks is welded on the base plate to support the specimen
Abrasive Charges - 1” dia ball 10 nos, 0.75” dia ball 35 nos, 0.50” dia ball 25nos - 1 Set

Drying Oven, Electronic weighing balance and mould to prepare the test sample available at extra cost
