In recent years, effective additives, like superplasticizers, have become the main topical issue in the study of low water demanding binders in solving the problem of the shortage of Portland cement. Mechanical and chemical activation of the binder, for instance the addition of active mineral compounds, increasing the flexibility of the
cement and expanding the use of superplasticizers, allows saving a great deal of the cement. Factors related to the rise of the cement shortages, the reduction of high quality raw material resources, the growth of industrial waste and environmental problems are the main reasons, resulting in the extensive use of various mineral additives in cement materials.

Identifying seismic fault zones is crucial for assessing the seismic risks and therefore affecting the land cover plan for a specific area. Urban areas built on seismically active fault zones are more susceptible to earthquakes compared to areas covered with dense forests or agricultural lands. The North- West Iran, Aras Special Development Zones (SEZs) are one of the areas with prominent land cover in near future due to its reachability to multiple countries. Analyzing the relationship between land cover types and seismic fault zones in the Aras SEZ can provide valuable insights into the susceptibility of different land cover types to seismic events. We used Land Use/Land Cover (LULC) method to assess the impact of seismic fault zones on land use in the Aras SEZs which involves evaluating the potential impact of earthquakes on different land uses and activities. This assessment can help identify areas that are most susceptible to seismic hazards and prioritize them for risk mitigation measures. In conclusion, our assessment of seismic fault risks on spatial planning and development in Aras SEZs suggests valuable insights to ensure the safety and resilience of future investments and developments.

Fiber Reinforced Polymer (FRP) rebars are made by pultruding or pulling continuous fibers, typically glass or basalt fibers, through a resin matrix. The resulting composite material is strong, lightweight, and corrosion-resistant. These bars are used as a substitute for traditional steel reinforcement bars (rebar) in certain applications where corrosion resistance and non-conductivity are important, or where weight reduction is a priority

Today, with the development of the construction industry, the demand for cement is also increasing. In increasing the volume of construction, cement is one of the resources available at the price of finished objects is achieved through cost reduction due to the use in the construction of modern high-quality building materials and products with lower energy consumption and with improved characteristics. Of particular importance is the production of effective cements based on industrial waste. On a global scale, special attention is paid to the development of new compositions of cements that increase the fire resistance of building structures and the most important task of research in this direction is the development of compositions based on industrial waste for Portland cement. When developing composite additives and based on them new compositions of highly effective composite Portland cement, in this direction it is necessary to substantiate a number of the following scientific solutions, in particular: development of new methods for the production of effective types of building products based on composite additives; development of new compositions for the production of nanocements with the participation of secondary raw materials; increase of concrete strength indicators on sulfate-resistant cements; optimization of the composition of raw materials in obtaining energy saving clinkers and cements; modernization of production technologies for white and decorative Portland cement; to increase the production of auxiliary cements, the use of alternative sources of active mineral additives and filler additives.
