Atmospheric Consistometer

The NCCJ Atmospheric Consistometer conditions cement slurries at atmospheric pressure and records slurry consistency against time and temperature. It has two test cells with independent temperature control, so two slurries can be tested at different temperatures at the same time.

How it works

Slurry is placed in a 470 ml slurry cup fitted with a mixing paddle on a removable cone-point threaded rod. The cup sits in a heated water bath and the drive turns at 150 plus or minus 15 rpm. The resistance of the slurry is reported as consistency over 0 to 100 Bc. Maximum bath temperature is 93 °C. Target temperature, current temperature, current consistency, target time and elapsed time for both cells are shown on the touch screen, together with a live consistency curve for each cell.

The water bath is designed to be taken apart for cleaning. The slurry cup uses a threaded connection and can be opened with a special tool or an ordinary wrench, which reduces wear of the rubber ring and the cup. The instrument requires cooling water at 0.2 to 0.5 MPa through a 10 mm inside diameter connection. Heater power is 2,400 W and total input power 2,600 W, at 100 to 110 V, 60 Hz or 220 V, 50 Hz. Dimensions are 54 x 65 x 65 cm (W x D x H) and mass is 75 kg.
