MORTAR PENETROMETER:

AS PER ASTM: C 403

Introduction:

It is used for finding out the rate of hardening of mortars sieved from concrete mixtures, by means of penetration needles of different cross-sectional areas.

General Description and Specifications:

• The instrument consists of a barrel housing a calibrated spring and a stem graduated from 0-70 kg x 1 kg.
• Six interchangeable penetration needles of areas 645, 323, 65, 32 and 16 mm sq. are provided.
• The penetration resistance is measured by the force exerted to penetrate the mortar by 25 mm and is indicated by a sliding ring on the stem, which is graduated.
