“…There are several methods for calculating the stress intensity factor in mode I from the results obtained from the described test (Bower, 2010;Elices, Guinea, Gómez, Planas, & Gomez, 2002). The authors of this article used the equation according to ASTM described in (Brown & Srawley, 1966):…”

The article describes a computer analysis of the pull-out test used to calculate the force needed to pull out a rock fragment and determine the shape of this broken fragment. The analyzed material is sandstone and porphyry. The analysis included the first approach to using own subroutine in the Simulia Abaqus system, that is, which task is undertaken to accurately determine the crack path of the Finite Element Method model. The work also contains a description of laboratory tests and analytical considerations.

“…On the other hand, the pullout test (CAPO-TEST), lock test, friction transfer test, break-off, and penetration resistance test are demonstrations of partially destructive methods. Since these partially destructive methods may inflict minimal damage and have no impact on the structural integrity, they are commonly referred to as Non-Destructive Tests (NDTs) in many different circumstances (Sourav et Despite their limitation to the exterior concrete layer of structures, pull-out (CAPO-TEST) tests have been demonstrated to be a dependable method for the in-situ assessment of concrete strength (Brencich 2015). Among the several non-destructive tests that can be employed, it is widely acknowledged that pull-out tests provide the greatest potential for being accepted as a reliable indicator of determining the in-place compressive strength of concrete (Sayed 1987).…”

The CAPO-TEST, also known as the pull-out test, is gaining popularity as a method for estimating the compressive strength of existing concrete structures due to its reliability, less structural damage compared to core collection, and quick in-place strength. The manufacturer of the pull-out machine has provided a general correlation for assessing the in-place concrete strength of stone chip-based concrete. Many of the concrete buildings in Bangladesh are made of brick chip-based concrete. In a few projects in Bangladesh, the CAPO test has been used to assess the concrete strength of existing structures. However, the reliability of this test for concrete made of brick chips has yet to be investigated. Twenty columns from five distinct structures, which varied in age from ten to forty-five years at the time of testing, underwent the CAPO and core tests for this study. Based on the fundamental findings of this investigation, a general correlation has been established regarding concrete composed of brick chips. Since no correlation has been established using the CAPO test to assess the strength of concrete composed of brick chis, this study suggested a general correlation between pull-out force and concrete core strength.

“…The CAPO-Test, which is a non-destructive technique, is used to estimate the strength of concrete at specific test areas 11 . Although pull-out (CAPO-Test) tests are limited to the external concrete layer of structures, they have been proven to be a reliable technique for evaluating the in-place strength of concrete 2 . Pull-out tests are considered to be one of the most reliable non-destructive methods for measuring the in-place compressive strength of concrete 12 .…”

This study presents the findings of an extensive investigation to evaluate the precision and reliability of a non-destructive CAPO-Test in estimating the in situ compressive strength of concrete made from machine-crushed brick aggregates. To estimate the compressive strength of concrete built from brick and stone aggregates for several target strengths at various ages, the CAPO-Test, core test, and standard cylinder test were used. The results of the core test and cylinder test are correlated with the CAPO pullout force, demonstrating a strong relationship between pullout force and compressive strength. The results suggest that the CAPO-Test displays estimated strengths ranging from 5 to 17% of the cylinder strength and 0–6% of the core strength for concrete containing brick chips. The study validates the CAPO-Test's reliability in conducting in-situ concrete strength assessments.
