Air Content of Freshly Mixed Concrete by the Pressure Method ASTM C231/C231M ||MaawaWorld||


 Welcome to Air Content of Freshly Mixed Concrete by the Pressure Method ASTM C231 ||MaawaWorld||

Scope* 1.1 This test method covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with a change in pressure. 1.2 This test method is intended for use with concretes and mortars made with relatively dense aggregates for which the aggregate correction factor can be satisfactorily determined by the technique described in Section 6. It is not applicable to concretes made with lightweight aggregates, air-cooled blastfurnace slag, or aggregates of high porosity. In these cases, Test Method C173/C173M should be used. This test method is also not applicable to nonplastic concrete such as is commonly used in the manufacture of pipe and concrete masonry units. 1.3 The text of this test method references notes and footnotes that provide explanatory information. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. #AirContent #AirMeter #PressureMethod #FreshlyMixedConcrete #Standard #CivilEngineering #C231/C231M #ASTM #AASHTO #Maawa #World CMU Blocks Test Calculations - Concrete Masonry Units ASTM C140 ||MaawaWorld|| https://www.youtube.com/watch?v=IOllj...

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
