ISO 13315-1:2012 混凝土及混凝土结构的环境管理.第1部分:一般原则

This part of ISO 13315 provides a framework and basic rules on environmental management related to concrete and concrete structures. This includes the assessment of the environmental impacts and methods of implementing environmental improvement based on the assessment. This part of ISO 13315 is used when assessing the environmental impacts and implementing the environmental management of concrete and concrete structures for the environmental consideration in activities related to the production of concrete constituents, the production, recycling and disposal of concrete, and the design, execution, use and demolition of concrete structures. It is applied for their entire lifecycles, respective stages of the lifecycles, or certain ranges of the lifecycles. This part of ISO 13315 is relevant to newly produced concrete and newly constructed concrete structures, and also existing concrete and concrete structures. This part of ISO 13315 applies not only to single concretes but also to concrete families and not only to single concrete structures but also to concrete structure complexes. For materials other than concrete, the related ISO standards are applied where available. In the case where no ISO standard is available, such materials are appropriately dealt with referring to this part of ISO 13315 and the normative references. The environments covered by this part of ISO 13315 include global, regional and local environments. The indoor pollution of buildings and the environments for workers in concrete producing plants and on concrete structure construction sites are not specifically covered by this part of ISO 13315. This part of ISO 13315 does not directly deal with the environmental impacts resulting from the operation of equipment installed in concrete structures. However, the special properties of concrete and concrete structures affecting the operational efficiency of such equipment are considered in this part of ISO 13315. This part of ISO 13315 covers secondary effects of the production of concrete and execution of concrete structures. This part of ISO 13315 may also cover the economic and social effects of environmental consideration in the production of concrete and execution of concrete structures. NOTE 1 NOTE 2 The working environments of plants and construction sites are generally prescribed by industrial safety and health laws. NOTE 3 In buildings, global warming substances are mainly emitted from energy consumption due to the operation of heating, ventilating and air-conditioning equipment. NOTE 4 The beneficial effects such as thermal mass and other functions of concrete and concrete structures may be taken into account. NOTE 5 The secondary effects of the production of concrete include the future possibility of leaching of heavy metals from concrete or the absorption of heavy metals from the environment, the effect of waste treatments on the environment, etc.  1

Environmental management for concrete and concrete structures - Part 1: General principles

ASTM C418-12 用喷砂法测定混凝土抗磨性的标准试验方法

1.1 This test method covers determination of the abrasion resistance characteristics of concrete by subjecting it to the impingement of air-driven silica sand. It is intended for use as a basis for the development of informed judgment. 1.2 The values stated in SI units are to be regarded as the standard. Inch-pound units are shown for information purposes in parentheses. 1.3 This standard does not purport to address 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. Note 1???Users of this test method are advised that there are known safety hazards associated with the use of silica as a blasting media. Consult the silica manufactures MSDS to insure that the latest recommended health and safety practices are being followed. Note 2???Other procedures are available for measuring abrasion resistance of concrete surfaces in addition to subjecting it to air driven silica sand. Consideration should be given to other methods of testing as outlined in ASTM C779/C779M, ASTM C944, and ASTM C1138. The test method most closely representing service conditions should be used. 1.4 The text of this standard references notes and footnotes which are provided as explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.

5. Significance and UseTop Bottom 5.1 Information concerning magnitude of compression and rate-of-consolidation of soil is essential in the design of earth structures and earth supported structures. The results of this test method may be used to analyze or estimate one-dimensional settlements, rates of settlement associated with the dissipation of excess pore-water pressure, and rates of fluid transport due to hydraulic gradients. This test method does not provide information concerning the rate of secondary compression. 5.2 Strain Rate Effects: 5.2.1 It is recognized that the stress-strain results of consolidation tests are strain rate dependent. Strain rates are limited in this test method by specification of the acceptable magnitudes of the base excess pressure ratio during the loading phase. This specification provides comparable results to the 100 % consolidation (end of primary) compression behavior obtained using Test Method D2435. 5.2.2 Field strain rates vary greatly with time, depth below the loaded area, and radial distance from the loaded area. Field strain rates during consolidation processes are generally much slower than laboratory strain rates and cannot be accurately determined or predicted. For these reasons, it is not practical to replicate the field strain rates with the laboratory test strain rate. 5.3 Temperature Effects: 5.3.1 Temperature affects the rate parameters such as hydraulic conductivity and the coefficient of consolidation. The primary cause of temperature effects is due to the changes in pore fluid viscosity but soil sensitivity may also be important. This test method provides results under room temperature conditions, corrections may be required to account for specific field conditions. Such corrections are beyond the scope of this test method. Special accommodation maybe made to replicate field temperature conditions and still be in conformance with this test method. 5.4 Saturation Effects: 5.4.1 This test method may not be used to measure the properties of partially saturated soils because the method requires the material to be back pressure saturated prior to consolidation. 5.5 Test Interpretation Assumptions?/i>The equations used in this test method are based on the following assumptions: 5.5.1 The soil is saturated. 5.5.2 The soil is homogeneous. 5.5.3 The compressibility of the soil particles and water is negligible. 5.5.4 Flow of pore water occurs only..........
