Guide to Formed Concrete Surfaces 成型混凝土表面指南
发布日期: 2014-01-01
施工团队的主要目标是生产符合项目规范和预期的现浇混凝土表面。尽管存在各种描述、解释和方法来实现铸态混凝土表面,但不同混凝土表面的定义并不统一。本文件定义了成型混凝土表面的四个质量等级,并提供了实现和评估这些等级的方法。这些质量等级由三个表面光洁度类别确定:1)模板饰面;2) 混凝土表面空隙率;3)形式特征- 饰面材料。根据德国混凝土协会(DBV)的建议(Merkblatt-Sichtbeton Deutscher Beton-und Bautechnik Verein e.V.2004),使用表格定义了分类的基本程序。本指南有助于项目业主、设计团队、承包商、模板和混凝土供应商以及所有其他各方对如何生产更明确定义的现浇混凝土表面达成更具体的理解。其他各方应了解生产成型混凝土规定表面的程序、流程和成本。 本指南还讨论了与混凝土表面相关的所有施工阶段,从规划、工程描述、施工到混凝土表面验收。本指南可供规范制定者(建筑师/授权设计专业人员)和承包商作为定义、规定和评估混凝土表面的补充工具使用,并为混凝土表面规范和预期的制定提供指导。有关成型混凝土表面施工后处理的信息,请参考ACI 303R-12。本指南还描述了综合使用的整个过程,包括混凝土表面团队的创建及其在施工过程中定义的角色和职责。
The primary goal of the construction team is to produce as-castconcrete surfaces that meet project specifications and expectations. Although various descriptions, interpretations, and methods exist to achieve an as-cast concrete surface, no unified definitions of different concrete surfaces exist.This document defines four quality levels of formed concrete surfaces and provides methods to achieve and evaluate them. These quality levels are identified by three surface finish categories: 1) form facing; 2) concrete surface void ratio; and 3) characteristics of form-facing materials. The basic procedures for classification are defined using tables derived from recommendations of the German Concrete Association (DBV) (Merkblatt Sichtbeton Deutscher Beton- und Bautechnik-Verein e.V. 2004).This guide assists the project owner, design team, contractor, formwork and concrete suppliers, and all other parties in reaching a more specific understanding of how to produce a more clearly defined as-cast concrete surface. All other parties should understand the procedures, processes, and costs for producing defined surfaces of formed concrete. The guide also discusses all phases of construction relating to concrete surfaces from planning, description of work, and construction through acceptance of a concrete surface.This guide can be used by both specifier (architect/licensed design professional) and contractor as a supplemental tool for defining, specifying, and evaluating concrete surfaces and offers guidance to the development of concrete surface specifications and expectations. Please refer to ACI 303R-12 for information regarding postconstruction treatment of formed concrete surfaces.This guide also describes an entire process for comprehensive use, including the creation of a concrete surface team and its defined roles and responsibilities in the construction process.
