Texas Concrete Cutting A-Core

18/01/2018  Texas concrete cutting follows the same process as concrete cutting anywhere in the United States.It includes techniques used to cut into concrete, stone, terra-cotta, or brick. Sometimes concrete cutting and breaking is performed to remove small sections of concrete to build doorways or utility holes, and other times it is needed as a part of demolition.

TECHNICAL CHECKLIST CONCRETE CORE TESTING

Strength level of concrete in the area represented by core tests is considered adequate when the average compressive strength of the three cores is equal to at least 85% of the specified compressive strength and no single core strength is less than 75% of the specified compressive strength. References: ACI 318-08, Section 5.6.5.4

Main Challenges of Concrete Coring FPrimeC Solutions Inc.

07/02/2017  When the purpose of coring is to evaluate the compressive strength of concrete, the minimum diameter of concrete core should be at least three (3) times the nominal maximum aggregate size. Different codes and standards set different values for the minimum diameter of concrete cores, ranging from 75 mm (in Australia) to ideal 150 mm (Britain). However, 100 mm core is a practical size
