ABSTRACT
The study examined the agents responsible for self-healing concrete in modern construction. Survey research design was employed for the study; the study population was made up of 600 construction workers in the south-east geopolitical zone of Nigeria. 240 workers were used as sample using taro yammney formula to determine the sample size and simple random sampling technique to determine which of the 600 workers should be selected as sample. Mean and analysis of variance (ANOVA) were used for data analysis. From the findings, bacterial, mineral additives and adhesive agents are responsible for self-healing in concrete and no significant difference exist in the rating of the agents on different sizes of buildings. Therefore, self-healing agents are essential in the achievement of sustainable concrete in modern construction. Building professionals should be trained on self-healing concrete. Government should ensure the availability of the agents and subsidize its price. The public should be sensitized on self-healing concrete through seminars and advertisement by the Council Registered Builders of Nigeria (CORBON).
Keywords: self-healing agents; Self-healing process; Impact of self-healing concrete.
