Experiment 2: Preparation and Testing of Cement Slurries 1. Purpose The main task of the experiment is to learn preparation and testing of cement slurries. 2. Equipments (1)Electronic-Balance (2)Mixing Devices (3)Mud-Balance (4)Rotational Viscometer (5)Atmospheric Consistometers 3. Experimental contents 3.1 Slurry Preparation The required quantity of water (352g) shall be placed in the mixing container (Fig. 1), the mixer turned on “slow” speed (4000 RPM), and the cement sample (800g) added in not more than 15 seconds. After all of the cement has been added to the water, the cover shall be placed on the mixing container and stirring shall be continued under “high” speed (12000 RPM) for 35 seconds. 3.2 Determination of Slurry Density Cement slurry density should be determined by use of the mud balance (Fig.2). After the cement slurry being poured into the mud-balance cup, should be puddle 25 times to eliminate entrapped air. Fig.2 Mud Balance 3.3 Determination of rheological properties The rheological behavior of the slurry was measured using a rotational viscometer (Fig.3) and following the procedure: a) The cement slurry should be prepared in accordance with Section 1. b) The prepared cement slurry should then be poured immediately into the slurry container of an atmosphere pressure consistometer which has been preheated Fig.1 Mixing Devices
