  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

  Welcome to Density - Specific Gravity of Hydraulic Cement ASTM C188/AASHTO T133 Urdu/Hindi || #MaawaWorld || Scope* 1.1 This test method covers the determination of the density of hydraulic cement. Its particular usefulness is in connection with the design and control of concrete mixtures. 1.2 The density of hydraulic cement is defined as the mass of a unit volume of the solids. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. #DensityCement #SpecificGravityCement #DensitySpecificGravity #ASTMC188 #AASHTOT133 Bricks Testing - Compressive Strength & Water Absorption ASTM C62, C67 Urdu/Hindi ||MaawaWorld|| https://ww

  Welcome To Bricks Testing - Compressive Strength & Water Absorption ASTM C62 , C67 Urdu/Hindi || #MaawaWorld || Standard Test Methods for Sampling and Testing Brick and Structural Clay Tile. ASTM C67 Scope* These test methods cover procedures for the sampling and testing of brick and structural clay tile. Although not necessarily applicable to all types of units, tests include modulus of rupture, compressive strength, absorption, saturation coefficient, effect of freezing and thawing, efflorescence, initial rate of absorption and determination of weight, size, warpage, length change, and void area. (Additional methods of test pertinent to ceramic glazed facing tile are included in Specification C126.)
