The microstructure of cement paste is extremely complex and heterogeneous, consists of randomly distributed phases with an arbitrary geometry, formed during the hydration process. The key phase of cement paste –calcium silicate hydrate exhibits distinct viscoelastic behavior causing creep in cement-based ...

Research is conducted on the cracking problem of the side walls of ultra-long seamless basement structures under high-temperature and sunny construction environments in summer. Long term temperature monitoring was conducted on a basement under construction in the Modern Service Industry Park of ...

Extreme value theory is a theory that deals with situations that are extremely far from the median of a probability distribution. It is often used to analyze situations with rare probabilities, such as earthquakes and floods that occur once in a hundred years. It is often used ...

In various time periods, interest to RC structures made of expansive concretes was very different: from admiration after its successful utilization in the real practice of civil engineering works (for instance, jointless self-stressed and post-tensioned slab-on-ground with dimensions of 144x72 m2) to ...

This paper provides an in-depth discussion of China's rich experience in the field of building cost engineering development and application, especially focusing on the current development of assembly building, which is the most representative of the process of ...

The current state of reservoirs in urban areas is one of the characteristics of the ecology of the urban system and its social attractiveness. Therefore, the development of criteria for a comprehensive assessment of reservoirs in urbanized areas in order to develop ...

The article presents a new solution to reduce the load of phosphorus and nitrogen on urban wastewater treatment plants, basedon the use of semi-burnt dolomite to extract these elements from sludge waters. The efficiency of the proposed method is compared with existing purification technologies using ...

The purpose of this article is to analyze the influence of deflections of supporting floors on the crack resistance of floor-by-floor supported masonry walls, depending on the method of their connec-tion with the reinforced concrete floor. This article shows that the deflection of ...

In modern economic conditions, the management of transport and logistics flows is associated with the universal penetration of digital technologies. Digitalization allows for the optimization of the entire supply chain, including transportation and warehousing operations. Digital ...

Ultra-rapid quenching from the melt makes it possible to obtain a significant refinement of the structural components of alloys, a significantincrease in the mutual solubility of components during the formation of solid solutions, and the release of metastable phases. When using the ultrafast quenching ...
