L- 102 Cement Testing: Quick Revision for SSC JE, RRB JE & Sub-Engineer Exams

quick revision guide on cement testing for SSC JE, RRB JE, and Sub-Engineer exams: 1. Field Tests of Cement Color: Should be uniform grey with a greenish shade. Texture: Smooth when rubbed between fingers. Lump Formation: No lumps should be present (indicates moisture absorption). Temperature: Feels cool when inserted in hand. 2. Laboratory Tests of Cement A. Fineness Test Determines the particle size of cement. Method: Sieve test (90-micron IS sieve) or Air permeability method (Blaine’s apparatus). Limit: Should not exceed 10% retained on 90-micron sieve. B. Consistency Test Determines normal consistency (water required for standard mix). Method: Vicat’s apparatus. Limit: Around 25%–35% water by weight of cement. C. Setting Time Test Determines initial and final setting time. Method: Vicat’s apparatus. Limits: Initial Setting Time: ≥30 min (OPC 33, 43, 53 Grade). Final Setting Time: ≤600 min. D. Soundness Test Determines volumetric stability (expansion due to lime or magnesia). Method: Le-Chatelier’s apparatus. Limit: Should not exceed 10 mm expansion. E. Compressive Strength Test Determines cement’s strength after setting. Method: Mortar cubes (1:3 cement-sand ratio) tested in a UTM. Limits (as per IS 4031-1988): 3 days: 16 MPa 7 days: 22 MPa 28 days: 33 MPa (for OPC 33 grade) F. Specific Gravity Test Determines density of cement. Method: Le Chatelier Flask or Pycnometer. Limit: Around 3.15. Important IS Codes for Cement Testing IS 4031 – Methods of Physical Tests IS 269 – OPC 33 Grade IS 8112 – OPC 43 Grade IS 12269 – OPC 53 Grade This should cover the most important cement testing points for SSC JE, RRB JE, and Sub-Engineer exams. 🚀 Let me know if you need PDF notes or MCQs!
