Aggregate Impact Value Test Apparatus

Aggregate Impact Value Test Apparatus: MTAT -14

It may be defined as the material to resist impact is known as toughness. Due to movement of vehicles on the road the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregates should therefore have sufficient toughness to resist their disintegration due to impact. This characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load.

Description

Technical Specification:-

The instrument consists of a circular base with two vertical guides.
The hammer of weight kg can be raised to fall freely down the vertical guides.
The height of fall can be adjusted through
The hammer is provided with a locking arrangement.
The hammer falls freely to the base and is removable for emptying.
Aggregate impact value test apparatus is Supplied complete with metal measures dia x high (for specimen preparation) and tamping rod long x dia.
Determining the aggregate impact value of coarse aggregate. Consists of a base weighing between 22-30 kg with a lower surface of not less than 30cms and support columns to form a rigid frame work around quick release trigger mechanism to ensure an effective free fall of the hammer during test. The free fall can be adjusted through 380+-5.0 mm. The hammer is provided with a locking arrangement
A metal TUP (hammer) weighing 13.5 to 14.0 kg, the lower end of in cylindrical shape, 100 mm in diameter and 5 cm long with a 2 mm chamfer I at the lower edge, and^ case hardened.
Complete with a cylindrical cup, 102 mm dia x 50 mm depth, one measure 75mm dia x 50 mm deep and tamping rod of circular cross-section 10 mm in diameter and 230 mm long, rounded at one end.

Accessories:-

Tamping rod
Cylindrical measure
