Compressive Strength of Concrete Cylinder [Urdu/Hindi] Part-3 ASTM C39/AASHTO T22

Compressive Strength of Concrete Cylinder [Urdu/Hindi] Part-3 ASTM C39/AASHTO T22 *Scope* This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a density in excess of 800 kg/m3 [50 lb/ft3]. The program requires a working knowledge of the following ASTM test methods and practices. Referenced Documents. • C31/C31M Practice for Making and Curing Concrete Test Specimens in the Field • C42/C42M Test Method for Obtaining and Testing Drilled Cores and Sawed Beams of Concrete • C192/C192M Practice for Making and Curing Concrete Test Specimens in the Laboratory • C617 Practice for Capping Cylindrical Concrete Specimens • C670 Practice for Preparing Precision and Bias Statements for Test Methods for Construction Materials • C873 Test Method for Compressive Strength of Concrete Cylinders Cast in Place in Cylindrical Molds • C1077 Practice for Laboratories Testing Concrete and Concrete Aggregates for Use in Construction and Criteria for Laboratory Evaluation • C1231/C1231M Practice for Use of Unbonded Caps in Determination of Compressive Strength of Hardened Concrete Cylinders • E4 Practices for Force Verification of Testing Machines • E74 Practice of Calibration of Force-Measuring Instruments for Verifying the Force Indication of Testing Machines

MUD MORTAR

Clay lumps are collected and are wetted with water and allowed to mature for 1 or 2 days. It is kneeded well until it attains required consistancy. Sometimes fibrous materials like gobber is added in the mix. It prevents cracks in the plaster. If plaster is to be used for outer walls, it is sprayed or painted with bitumen. It is cheap mortar. Its durability is less. It is normally used for the construction of temporary sheds and cheap houses in rural areas.

Properties of Bricks

Properties of Bricks The following are the required properties of good bricks: (i) Colour: Colour should be uniform and bright. (ii) Shape: Bricks should have plane faces. They should have sharp and true right angled corners. (iii) Size: Bricks should be of standard sizes as prescribed by codes. (iv) Texture: They should possess fine, dense and uniform texture. They should not possess fissures, cavities, loose grit and unburnt lime. (v) Soundness: When struck with hammer or with another brick, it should produce metallic sound. (vi) Hardness: Finger scratching should not produce any impression on the brick. (vii) Strength: Crushing strength of brick should not be less than 3.5 N/mm2. A field test for strength is that when dropped from a height of 0.9 m to 1.0 mm on a hard ground, the brick should not break into pieces. (viii) Water Absorption: After immercing the brick in water for 24 hours, water absorption should not be more than 20 per cent by weight. For class-I work...
