ACI 347.3R-13 PDF Download

ACI 347.3R-13 is a standard titled "Guide to Formed Concrete Surfaces." The purpose of this standard is to provide guidelines for achieving and evaluating different quality levels of formed concrete surfaces. It includes definitions and methods to achieve these quality levels, which are categorized by form facing, concrete surface void ratio, and characteristics of form-facing materials. The classification procedures are derived from recommendations of the German Concrete Association (DBV).

This guide is intended to be used by various parties involved in the construction process, including the project owner, design team, contractor, formwork and concrete suppliers. It aims to improve the understanding of how to produce defined as-cast concrete surfaces and discusses all phases of construction related to concrete surfaces, from planning to acceptance.

The guide can be used by both specifiers (architects/licensed design professionals) and contractors as a supplementary tool for defining, specifying, and evaluating concrete surfaces. It also offers guidance for developing concrete surface specifications and expectations. Additionally, the standard provides information on postconstruction treatment of formed concrete surfaces in ACI 303R-12.
