SOUNDNESS TEST OF CEMENT
SOUNDNESS TEST OF CEMENT AIM: To identify how much volumetric expansion the cement sample goes through once it is set. APPARATUS REQUIRED: 1. Chatelier test equipment 2. Metal tray 3. Weighing balance 4. Measuring cylinder 5. Thermometer SAMPLE: The cement absorbed must be fine-ground material to which the addition of sufficient amount of water can harden both in water and in the air due to the chemistry of reaction of its materials with water and to have the capacity of binding together the right materials. Oxygenated (Reference IS: 3535 - 1986) PROCEDURE: 1. Before commencing setting time test, do the consistency test to obtain the water required to give the paste normal consistency (P). 2. Prepare a paste by adding 0.78 times the water required to give a paste of standard consistency (i.e. 0.78P) as per IS 4031 (Part 4)-1988. 3. Lightly oil the Le-chatelier mould and place it on a lightly oiled glass sheet. 4. Fill the mould with the prepared cement paste. In the process of ...
