Test methods adapted for alternative and recycled, porous aggregate materials (Part 3 - Water absorption) (NT TR 550)

NT TR 550

  • This is the third report in a series of projects dealing with test methods for mainly alternative and recycled aggregates (1292-96 and 1393-97). This study focuses on the problem of water absorption of porous aggregates in atmospheric pressure in accordance with EN 1097-6 Determination of particle density and water absorption, and the implication on durability aspects.

Lightweight aggregates for railway embankments - Resistance to cyclic compressive loading (NT BUILD 503)

NT BUILD 503

  • The method specifies the procedures for the determination of the compressive deformation of lightweight aggregates during a fatigue test carried out with cyclic compressive load. The method is primarily designed for aggregates to be used in railway embankments and is applicable for lightweight aggregates and recycled aggregates with maximum particle size 32 mm.

Aggregates: Size distribution (NT BUILD 486)

NT BUILD 486

  • The method can be applied to determine the size distribution of aggregates in different materials such as hardened mortars and concrete. The maximum aggregate size which can be measured depends on the size of the measured image.

    The measurements can be performed using thin sections or other specimens where the aggregates can be distinguished from the background.
