Cement Testing: Essential Physical Properties (ESE, SSC JE, RRB JE, UPPSC Civil Exams)
​Welcome to CIVIL GYAN CENTER! I'm Shree Vardhan Srivastava, and in this comprehensive video, we dive deep into the crucial Physical Tests of Cement, a foundational topic for all Civil Engineering competitive exams.
​Cement is the most vital binding material in construction. Knowing its quality through rigorous testing is non-negotiable for building safe and durable structures. This video covers the theoretical concepts, practical procedures, and the significance of each test, making it perfect for your exam preparation.
​🔍 What You Will Learn in This Video:
​We systematically cover the following essential tests, which are frequently asked in exams like ESE (IES), SSC JE, RRB JE, UPPSC Polytechnic Lecturer, and other state-level Civil Engineering examinations:
​Fineness Test of Cement:
​Purpose: To check the particle size and surface area of cement (affecting hydration rate).
​Methods: Sieve analysis and Air Permeability Test (Blaine's apparatus).
​Standard Consistency Test:
​Purpose: To find the amount of water required to form a cement paste of standard workability.
​Apparatus: Vicat Apparatus.
​Setting Time Tests:
​Initial Setting Time: Time taken by the paste to start losing its plasticity.
​Final Setting Time: Time taken by the paste to lose its plasticity completely and attain sufficient hardness.
​Apparatus: Vicat Apparatus (using different needles).
​Specific Gravity Test:
​Purpose: To determine the density of cement particles (free from air).
​Apparatus: Le Chatelier's Flask or Pycnometer.
​Soundness Test:
​Purpose: To detect the presence of uncombined free lime or magnesia, which causes volume change (expansion) and cracking after setting.
​Apparatus: Le Chatelier's Apparatus and Autoclave.
​Strength Test:
​Compressive Strength: Testing the strength of cement mortar cubes.
​📚 Why This Video is Important for Your Exams:
​Whether you are preparing for a Junior Engineer (JE) or Assistant Engineer (AE) examination, questions on Cement Testing are guaranteed. This video provides:
​Clear Conceptual Clarity: Understand why we perform each test.
​Standard Values & IS Codes: Learn the required standard values for each test as per Indian Standard Codes (IS Codes).
​Apparatus & Procedure: Detailed explanation of the apparatus used (like the Vicat apparatus and Le Chatelier's flask) and the testing procedure.
