ASTM C1556-2011a(2016) 采用体积扩散测定水泥基混合料的表观氯离子扩散系数的标准试验方法
简介:5.1x00a0;This test method is applicable to cementitious mixtures that have not been exposed to external chloride ions, other than the negligible quantity of chloride ion exposure from sample preparation using potable water, prior to the test. 5.2x00a0;The calculation procedure described in this test method is applicable only to laboratory test specimens exposed to a sodium chloride solution as described in this test method. This calculation procedure is not applicable to specimens exposed to chloride ions during cyclic wetting and drying. Note 1:x00a0;The diffusion of ionic species in concrete occurs within the fluid-filled pores, cracks and void spaces. The concentration and valence of other ionic species in the pore fluid also influence the rate of chloride diffusion, and therefore, the apparent diffusion coefficient as determined by this test procedure. 5.3x00a0;In most cases, the value of the apparent chloride diffusion coefficient for cementitious mixtures changes over time (see Note 2). Therefore, apparent diffusion coefficients obtained at early ages may not be representative of performance in service. Note 2:x00a0;The rate of change of the apparent diffusion coefficient for cementitious mixtures containing pozzolans or blast-furnace slag is typically different than that for mixtures containing only portland cement. 5.4x00a0;The apparent chloride diffusion coefficient is used in Fick's second law of diffusion to estimate chloride penetration into cementitious mixtures that are in a saturated condition. 5.5x00a0;The apparent chloride diffusion coefficient is commonly used in chloride ingress models based on Fick's second law of diffusion. The apparent diffusion coefficient determined by this method includes bound chloride, so proper use of the apparent chloride diffusion coefficient to predict chloride ingress requires consideration of chloride binding. 5.6x00a0;The resistance to chloride penetration is affected by such factors as the environment, finishing, mixture composition, workmanship, curing, and age. 1.1x00a0;This test method covers the laboratory determination of the apparent chloride diffusion coefficient for hardened cementitious mixtures. 1.2x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3x00a0;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.

ASTM D512-2012 测定水中氯离子含量的标准试验方法
简介:Chloride ion is under regulation in waste water, and must, therefore, be measured accurately. It is highly detrimental to high-pressure boiler systems and to stainless steel, so monitoring is essential for prevention of damage. Chloride analysis is widely used as a tool for estimating the cycles of concentration, such as in cooling tower applications. Processing waters and pickling solutions used in the food processing industries also require dependable methods of analysis for chloride.1.1 These test methods cover the determination of chloride ion in water, wastewater (Test Method C only), and brines. The following three test methods are included: Sections Test Method A (Mercurimetric Titration)7 to14 Test Method B (Silver Nitrate Titration)15 to 21 Test Method C (Ion-Selective Electrode Method)22 to 29 1.2 Test Methods A, B, and C were validated under Practice D2777 x2013; 77, and only Test Method B conforms also to Practice D2777 x2013; 86. Refer to Sections 14, 21, and 29 for further information. 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. For a specific hazard statement, see 26.1.1. 1.5 A former colorimetric test method was discontinued. Refer to Appendix X1 for historical information.

ASTM C1556-2011 通过体积扩散测定水泥混合剂表观氯离子扩散系数的标准试验方法
简介:This test method is applicable to cementitious mixtures that have not been exposed to external chloride ions, other than the negligible quantity of chloride ion exposure from sample preparation using potable water, prior to the test. The calculation procedure described in this test method is applicable only to laboratory test specimens exposed to a sodium chloride solution as described in this test method. This calculation procedure is not applicable to specimens exposed to chloride ions during cyclic wetting and drying. Note 18212;The diffusion of ionic species in concrete occurs within the fluid-filled pores, cracks and void spaces. The concentration and valence of other ionic species in the pore fluid also influence the rate of chloride diffusion, and therefore, the apparent diffusion coefficient as determined by this test procedure. In most cases, the value of the apparent chloride diffusion coefficient for cementitious mixtures changes over time (See Note 2). Therefore, apparent diffusion coefficients obtained at early ages may not be representative of performance in service. Note 28212;The rate of change of the apparent diffusion coefficient for cementitious mixtures containing pozzolans or blast-furnace slag is typically different than that for mixtures containing only portland cement. The apparent chloride diffusion coefficient is used in Fickrsquo;second law of diffusion to estimate chloride penetration into cementitious mixtures that are in a saturated condition. The apparent chloride diffusion coefficient is commonly used in chloride ingress models based on Fickrsquo;second law of diffusion. The apparent diffusion coefficient determined by this method includes chemically bound chloride, so proper use of the apparent chloride diffusion coefficient to predict chloride ingress requires consideration of chloride binding. The resistance to chloride penetration is affected by such factors as the environment, finishing, mixture composition, workmanship, curing, and age.1.1 This test method covers the laboratory determination of the apparent chloride diffusion coefficient for hardened cementitious mixtures.1.2 The values stated in SI units are to be regarded as the standard.1.3 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.
