Cement

Cement particle testing standards published by ASTM and DIN cover standard test methods for particle size analysis of riprap materials, determination of fineness cement testing, and determination of particle size distribution by sieve analysis of masonry mortar.

ASTM D5519-15

Standard Test Methods for Particle Size Analysis of Natural and Man-Made Riprap Materials

1.1 These test methods cover the particle size and mass analysis of natural and man-made riprap and related materials, including filter stone or coarse bedding materials. 1.2 These test methods are generally intended for riprap and related materials. They are applicable for mixtures of stones screened from natural deposits, blast rock, processed materials from quarried rock, or recycled concrete. They are applicable for sizes 3 in. (75 mm) and above, with the upper size limited only by equipment available for handling and determining the mass of the individual particles. 1.3 Four alternate procedures are provided. There is a wide range in the level of effort and the precision of the test procedures. It is important for specifiers to indicate the test procedure. Test reports should clearly indicate which procedure was used. 1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 , unless superseded by this standard. 1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.6 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. Specific precautionary statements are given in Section 7 .

Methods of testing cement - Part 6: Determination of fineness; German version EN 196-6:2018

This document describes three methods of determining the fineness of cement. The sieving method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling the production process. The air-jet sieving method measures the retention on sieving and is suitable for particles which substantially pass a 2,0 mm test sieve. It can be used to determine the particle size distribution of agglomerates of very fine particles. This method can be used with test sieves in a range of aperture sizes, e. g. 63 µm and 90 µm. The air permeability method (Blaine) measures the specific surface area (surface area related to mass) by comparison with a reference material sample. The determination of the specific surface area serves primarily to check the consistency of the grinding process of one and the same plant. This method only enables a limited assessment to be made of the properties of the cement in use. The air permeability method may not give significant results for cements containing ultrafine materials. The methods are applicable to all the cements defined in EN 197-1.

Methods of test for mortar for masonry - Part 1: Determination of particle size distribution (by sieve analysis); German version EN 1015-1:1998+A1:2006 (Foreign Standard)

This standard specifies two methods of determining the particle size distribution of dry mixed or non hardened wet mixed mortars. The method of wet sieving is applicable to mortars containing normal weight aggregates and the method of dry sieving to morta
