117-10 Specification for Tolerances for Concrete Construction and Materials (ACI 117-10) and Commentary

ACI 117-10 Specification for Tolerances for Concrete Construction and Materials (ACI 117-10) and Commentary provides standard tolerances for concrete construction and materials. This document is intended to be used by specification writers and ACI committees writing standards as the reference document for establishing tolerances for concrete construction and materials. Commentary synopsis: This report is a commentary on the Specification for Tolerances for Concrete Construction and Materials (ACI 117). It is intended to be used with ACI 117 for clarity of interpretation and insight into the intent of the committee regarding the application of the tolerances set forth therein.
