Guide for Obtaining Cores and Interpreting Compressive Strength Results the limits on the time interval between coring and testing, and the basis for determining whether the concrete in the area represented by the core strengths is structurally adequate This guide presents procedures for obtaining and testing cores and interpreting results in accordance with ACI 318
214. 4-21: Obtaining Cores and Interpreting Core Compressive Strength . . . the limits on the time interval between coring and testing, and the basis for determining whether the concrete in the area represented by the core strengths is structurally adequate This guide presents procedures for obtaining and testing cores and interpreting results in accordance with ACI 301
Low Strength Results and Core Testing Q. - American Concrete Institute Coring should be done according to ASTM C42 C42M, “Standard Test Method for Obtaining and Testing Drilled Cores and Sawed Beams of Concrete” (refer to ACI 318-19, Provision 26 12 6 1(b)), unless modified by the LDP or BO (Provision 26 12 6 1(c)) Also, it’s good practice for someone experienced in ASTM C42 C42M to witness the coring

What is curing? - American Concrete Institute What is curing? Q What is curing? A Curing is action taken to maintain moisture and temperature conditions in a freshly placed cementitious mixture to allow hydraulic cement hydration and, if applicable, pozzolanic reactions to occur so that the potential properties of the mixture may develop (ACI 308)
