Concrete

Concrete!

Plain concrete, commonly known as concrete, is an intimate mixture of binding material, fine aggregate, coarse aggregate and water. This can be easily moulded to desired shape and size before it looses plasticity and hardens. Plain concrete is strong in compression but very weak in tension. The tensile property is introduced in concrete by inducting different materials and this attempt has given rise to RCC, RBC, PSC, FRC, cellular concrete and Ferro cement. Proportioning, mixing, curing, properties, tests and uses of plain concrete is dealt in detail. The other improved versions of concrete are explained and their special properties and uses are pointed out.

Particle-Size Analysis of Soils ASTM D422

Particle-Size Analysis of Soils  ASTM D422 GRAIN SIZE ANALYSIS SIEVE & HYDROMETER ANALYSIS Purpose : This test is performed to determine the percentage of different grain sizes contained within a soil. The mechanical or sieve analysis is performed to determine the distribution of the coarser, larger-sized particles, and the hydrometer method is used to determine the distribution of the finer particles. Standard Reference : ASTM D 422 - Standard Test Method for Particle-Size Analysis of Soils Significance : The distribution of different grain sizes affects the engineering properties of soil. Grain size analysis provides the grain size distribution, and it is required in classifying the soil. Equipment : Balance, Set of sieves, Cleaning brush, Sieve shaker, Mixer (blender), 152H Hydrometer, Sedimentation cylinder, Control cylinder, Thermometer, Beaker, Timing device. Test Procedure: Sieve Analysis: (1) Write down the weight of each sieve as

Slump Test of Concrete ASTM C143 [Urdu & Hindi]

Image
Slump Test of Concrete ASTM C143 [Urdu & Hindi] *Scope* The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch. The test is popular due to the simplicity of apparatus used and simple procedure. The slump test is used to ensure uniformity for different loads of concrete under field conditions. The program requires a working knowledge of the following ASTM test methods and practices. Referenced Documents ASTM Standards: • C31/C31M Practice for Making and Curing Concrete Test Specimens in the Field. • C138/C138M Test Method for Density (Unit Weight), Yield, and Air Content (Gravimetric) of Concrete. • C172 Practice for Sampling Freshly Mixed Concrete. • C173/C173M Test Method for Air Content of Freshly Mixed Concrete by the Volumetric Method. • C231 Test Method for Air Con
