Comprehensive Evaluation of Adhesive Compounds and Their Properties Involving Harrington’s Desirability Function

The increase in the volume of construction work carried out with chemical anchors has led to a corresponding growth in the supply of these products on the market. Anchors possess numerous characteristics, including strength, anchorage displacement, temperature, curing time, and cost. Designers face the challenge of choosing the optimal solution for specific construction conditions. In practice, this often results in choosing anchors with maximum strength and minimum cost, which is not always the best option for long-term use. The authors of this study propose addressing this challenge through a multi-criteria optimization method based on the Harrington function. For implementation, 18 criteria were used. They were derived from reference sources and experimental results. Tests were conducted under short-term and long-term static loading. Based on these tests, strength characteristics were determined, and statistical analysis was carried out to calculate coefficients of variation and confidence intervals for the mean values. Nine types of chemical anchors with different bases were tested: epoxy-based, acrylate-based, methacrylate-based, polyester-based, and epoxy-acrylate-based (five samples in each series). In this study, the assumption that all criteria have equal weight coefficients is made as a limitation. The results of the study are valid only for static loading of anchors in uncracked concrete. The optimal adhesive compound was determined for the basic winter and summer sets of criteria. The practical significance lies in the implementation of a multi-criteria optimization method for selecting the adhesive compound. This approach allows users to choose the optimal adhesive compound for their needs.
