The purpose of this research is to analyze the role of integrated components of sustainability in the construction industry in the construction projects of Imam Khomeini Port. For this purpose, a main hypothesis and three sub-hypotheses were developed. From the point of view of the purpose of this research, it is a development-oriented applied research, and from the point of view of methodology, it is descriptive-analytical (quantitative). The statistical population of this research includes specialists and construction experts of the Imam Khomeini Port Engineering System Organization, and the sample size was selected according to Kersey and Morgan's table by simple random sampling method of 120 people. The method of collecting information is library and field methods. Data analysis was done in two parts, descriptive statistics and inferential statistics using Pearson correlation coefficient, regression analysis and Friedman test by spss software. The findings indicate the confirmation of research hypotheses at a significance level of less than 0.05. Based on this, indicators of economic sustainability, social sustainability and environmental sustainability affect the success of construction projects.

Concrete is one of the most widely used materials in construction, and the reason for that is its hardness, durability and high resistance. Pores are usually filled with fluid. So far, nanostructures with regular and irregular shapes have been made from different materials, which in total form one of the most diverse categories of materials. In this regard, 30 samples were made and tested for compressive strength testing and 30 samples for tensile testing. The amount of nanosilica and nanoclay in three different ratios of 0.25, 0.50, and 0.75 of cement weight has been added to the concrete mixture. The obtained results show an increase in the compressive and tensile strength of concrete due to the addition of nanosilica and nanoclay

Every year, a significant portion of the country's credits and financial resources are allocated to investment in civil and infrastructural projects. Risk management can prevent cost escalation and assist in completing projects within the designated time and budget. This study aims to identify factors contributing to the lack of implementation of risk management in small-scale civil projects in the city of Abadan. The research utilizes a descriptive method for data collection and employs exploratory factor analysis and TOPSIS analytical methods to identify and prioritize the factors. The results indicate that the influential factors in the lack of implementing risk management include four main elements (technical risk barriers, project management and leadership obstacles, construction risk barriers, financial risk barriers), among which the option of insufficient knowledge of the contractor has priority over other options.
