Mortar Penetration Resistance Apparatus

The mortar penetration resistance apparatus is used to test the rate of hardness of mortars sieved from concrete mixtures.  It also determines the effects of variables such as temperature, cement, mixture proportions, additions and admixtures upon the time of setting and hardening of concrete.
