Standard Guide for Preparation of Concrete Surfaces for Adhered (Bonded) Membrane Waterproofing Systems 粘结(粘结)膜防水系统混凝土表面制备标准指南
发布日期: 2018-03-01
1.1 本指南提供了在应用粘附(粘结)防水材料之前准备混凝土表面的建议。 1.2 本指南主要针对新混凝土的安装,但也适用于现有混凝土安装。(另请参见ACI 116和ACI 546。) 1.3 本指南不适用于松散铺设系统、膨润土系统、铅等。 1.4 本指南不适用于涉及绝缘混凝土的应用。 1.5 本指南不适用于涉及轻质结构混凝土的应用。 注1: 一旦安装,很难从视觉上识别正常重量和轻质混凝土之间的差异。建议审查合同文件、混凝土批次或交货单或类似工作,以确定混凝土类型。 1.6 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值;因此,每个系统应相互独立使用。将两个系统的值合并可能会导致- 符合标准。 1.7 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 防水应用的成功取决于所涂混凝土表面的类型、平滑度和清洁度。本指南描述了通过移除或其他建设性修改可能影响防水系统性能的表面缺陷来调节或修复混凝土表面。它包括通过机械、化学和喷砂清理方法进行表面处理,以在防水系统和混凝土之间提供良好的附着力,以及各种表面污染物的影响和控制。 它还涉及评估混凝土含水量,以确保最佳初始粘结。(另见ACI 515。) 3.2 本指南无意为选择合适的防水系统提供指南;具体应用技术的使用;或泛水、终端、伸缩缝详图等的设计和安装(有关术语的定义,请参阅术语 D1079号 .) 3.3 本指南的目的不是提供控制穿过混凝土的水蒸汽驱动的指南,这可能会影响混凝土和防水材料之间粘结的长期性能。 3.4 本文所述的推荐程序是最低限度的;防水材料制造商可能要求更严格或更具体的混凝土表面处理程序,以应用制造商的特定系统。
1.1 This guide provides recommendations for the preparation of concrete surfaces prior to the application of adhered (bonded) waterproofing. 1.2 This guide is directed primarily toward installations of new concrete, but is also applicable for existing concrete installations. (See also ACI 116 and ACI 546.) 1.3 This guide does not apply to loose laid systems, bentonite systems, lead, or the like. 1.4 This guide does not apply to applications involving insulating concrete. 1.5 This guide does not apply to applications involving lightweight structural concrete. Note 1: Once installed, it is difficult to visually identify the difference between normal weight and lightweight concrete. It is recommended that a review of contract documents, concrete batch or delivery tickets or similar effort be performed to identify the concrete type. 1.6 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. 1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 The success of a waterproofing application depends on, among other things, the type, smoothness, and cleanliness of the concrete surface being coated. This guide describes conditioning or repairing of the concrete surface by the removal or other constructive modification of those surface defects that can affect the performance of the waterproofing system. It covers surface preparation by mechanical, chemical, and blast cleaning methods in order to provide good adhesion between the waterproofing system and the concrete as well as the effect and control of various surface contaminants. It also addresses the evaluation of concrete moisture content to ensure optimal initial bond. (See also ACI 515.) 3.2 This guide is not intended to offer guidelines for the selection of a suitable waterproofing system; the use of specific application techniques; or the design and installation of flashing, terminations, expansion joint details, etc. (For definitions of terms, see Terminology D1079 .) 3.3 This guide is not intended to offer guidelines for the control of water vapor drive through the concrete which could affect long term performance of the bond between the concrete and waterproofing. 3.4 The recommended procedures described herein are minimums; the waterproofing materials manufacturer may require more strict or specific procedures for the preparation of concrete surfaces for the application of the manufacturer's specific system.
