| Abstract [eng] |
The objective of this Master's thesis is to determine the effectiveness of different concrete admixtures in reinforced concrete structures exposed to a chloride-rich environment, utilizing both non-destructive and destructive testing methods. The Master's thesis is divided into three parts: a literature review, the methodology for the planned research, and the experimental results with conclusions. The literature review section examines various methods for determining the risk and rate of corrosion in reinforced concrete elements, as well as the influence of different chemically active environments on reinforced concrete structures. The research methodology section describes the tests and experiments planned during the course of the work, their procedures, and the instruments and principles by which the experiments will be conducted. The experimental results are described in the final section, where it was determined that the organic admixture is an ineffective additive for underground reinforced concrete structures exposed to chlorides. The research also demonstrated the effectiveness of the crystalline waterproofing admixture in saline and aqueous environments. |
