Hydraulic Shrinkage Mould 40x40x160 mm

The 62-L0009/G version is used for the determination of linear shrinkage of cement mortars.

Standards EN 12617-4 EN 12808-4 NF P15-413

62-L0009/G Shrinkage mould for 40x40x160 mm mortar prisms
Description

The 62-L0009/G version is used for the determination of linear shrinkage of cement mortars (EN 12617-4). The same mould can be used for testing grouts conforming to EN 12808-4 replacing the standard plugs with the 62-L0010/H2 and placing two 15x40x160 mm plastic inserts  62-L0010/H3 inside each compartment. See accessories. Three gang mould, individually tested with certified instruments. Made of special alloy steel, minimum hardness HV200. The shrinkage measurement has to be done with the 62-L0035/A Length comparator.

The 62-L0009 version, conforming to UNI 6687, slightly differ from the 62-L0009/G version and it is used for the same determination.

Weight approx.: 12 kg
