TYPES OF TEST ON BRICKS - civil engineering study Types of Tests On Bricks IS code 3495  Following tests are conducted on bricks to determine its suitability for construction work. Absorption test Crushing strength test Hardness test Shape and size Color test Soundness test Structure of brick Presence of soluble salts (Efflorescence Test)    WATER Absorption Test on Bricks - 3495 PART 2 Absorption test is conducted on brick to find out the amount of moisture content absorbed by brick under extreme conditions.  Apparatus: Oven,  Weight balance,  Tray PROCEDURE Take any five random bricks from a lot of brick as a specimen. Dry the specimen in a ventilated oven at a temperature of 105°C to 115°C till it achieves considerably constant mass. Cool the specimen to room temperature and take its weight (M1). Testing: When the specimen is completely dry, then immerse it in the clean water at the room temperature (27 ±2°C...

What are the properties of high density concrete in dry state? High density Concrete 1. High density concrete is those concrete which have best packaging with the presence of finest to coarse particles of substance of concrete which gives best denseness of concrete. 2. It is achieved by using the knowledge of concrete with skills. 3. It is achieved by using of some admixtures or additionally use of special ingredients of concrete 4. For making high density concrete first step is choosing the right materials for it. 5. It requires heavier aggregates with specific gravity of 3.5 to 4.which give 6. Some Natural aggregates used in High dense concrete is Limonite, Haematite, Magnetite,Barite etc. 7. like finest grade of cement.small to higher proportion of fine to coarse aggregate which gives better packaging of concrete and most important part is using of water reducing agent which removes extra part of water some plasticize,skilled labor who knows how to mix it. 8.for mixing or preparatio...
