  COMPRESSIVE STRENGTH TEST OF CEMENT AIM: To find out the compressive strength of cement. APPARATUS REQUIRED: 1. Cube mould (70.6mm X 70.6mm X 70.6mm) 2. Mixing pan 3. Trowel 4. Measuring Jar 5. Tamping Rod 6. Compressed test machine 7. Weigh balance SAMPLE: The cement to be used must be finely powdered material that when an adequate amount of water is added can harden both underwater and in the air resulting in a hardening of constituents through chemical interaction with water as also have a binding effect on the material that needs to be set. Formerly at 3535-1986 (Reference IS: 3535 - 1986 ) PROCEDURE: The standard sand confirming to IS 650 – 1966 is taken for the test. Take 200gm of cement and 600gm of standard sand in the proportion 1:3 by weight in a pan. Mix the cement and sand in dry condition with a trowel for 1minitues and then with water until the mixture is of uniform colour. The quantity of water shall be (p/4+3) % of combined weight of cement and sand where, p is t...
