Portland cement production is a major contributor to global CO2 emissions, and the scarcity of natural river sand limits conventional concrete production. Despite increasing interest in geopolymer concrete (GPC), studies...

Abstract Background and Objectives pediatric Cardiopulmonary resuscitation (CPR) is critical for saving children who experience cardiac arrest, but traditional teaching is often ineffective at improving clinical competen...

The new airport project in Sanya planned by government of Hainan Province of China, is located at Hongtangwan of Sanya City, that is, to build an offshore airport with an area of a 28 square kilometers. The construction ...

As the water pressure of shield tunnel increases, the key to tunnel construction is to strengthen the water resistance of joints. By analyzing the characteristics of stress and deformation of the gaskets in the joints of...

Changsha International Finance Center, the highest building under construction in Central China, is 452 meters high with structure of 93 ground layers and 5 underground layers and an embedded foundation depth of 42 meter...

After hydraulic reclamation of the dredger fill, the mud needs some time to deposit. The reinforcement treatment cannot be carried out until the sludge-water separation is completed and the separated water is drained. Th...

To study the deformation, failure and long-term stability of soft surrounding rock (mudstone) tunnel anchorage under heavy loads, the Changjiang River Bridge under construction is taken as an example, in which 1∶30 red...

This work introduces a novel geometrical and analytical modeling framework for predicting the stiffness properties of knitted composites, a class of materials known for their complex architectures and versatile mechanica...

Recycling of construction waste is essential for sustainable cement-based materials, yet the variable composition of recycled autoclaved aerated concrete (AAC) powder pose significant challenges when used in grouting app...

Reinforced concrete (RC) piers have been widely studied and applied in bridge construction practice. To ensure the normal operation of RC piers under corrosive environments and seismic effects, new corrosion-resistant ma...

En este artículo analizamos cómo se construye el "nosotros" policial, entendiendo que el mismo no responde a una construcción estable y perenne propia de una esencia ontológica invariable del "ser policial"; sino que...

INTRODUCTION. The linguistic complexity of the German legal text is considered. The relevance is due to the need for an in-depth study of the linguistic features of the German legal text, which is traditionally considere...

The global shift towards sustainability has driven significant advancements in construction methodologies. Among these innovations, 3D Concrete Printing (3DCP) stands out as a transformative technology that employs gantr...

Based on the ellipsoid theory of particle flows, that is, an ellipse sliding face is presented in the loosening zone at upper part of tunnels, a method is deduced to calculate the lateral earth pressure coefficient relat...

Based on a large-scale excavation adjacent to metro line, the design and construction schemes and monitoring data of metro structures during construction are analyzed. Some conclusions are drawn as follows: the movement ...

Vários estudos sobre a caracterização da identidade de gênero na mídia têm sinalizado que o eixo bipolar masculino-feminino vem orientando historicamente as narrativas identirárias, ao diferenciar homens e mulhere...

The geogrid and geocell with high tensile strength are meant to reinforce the mixture of natural gravel and recycled concrete aggregate made of the soild waste of construction. The reinforced cushion with variable stiffn...

With the help of ABAQUS FEM software, a numerical study is carried out on the mechanical properties of bent bolted connection in shield tunnel under the effect of preload, which offers theoretical evidence for the design...

Due to its high compressibility, low permeability and low consolidation property, the treatment of ultra-soft soil is very difficult, and the common method is hardly effective. For the ultra-soft soil in Tianjin Port, th...

In the current context, the development business functions as a strategic sector of the national economy, driving infrastructure growth in cities and regions. Its multiplier effect is explained by its comprehensive scope...

Based on the Winkler foundation model, the interactions of the frame structure, strip basement and soil foundation are simplified as a shear-flexural beam on elastic foundation. The different construction distances are c...

Abstract The Carroll group arises in the vanishing speed of light limit of the Poincaré group and was initially discarded as just a mathematical curiosity. However, recent developments have proved otherwise. Carroll and...

The extended evolutionary synthesis (EES) emphasizes integrative approaches to understanding distributed adaptability, incorporating development and intergenerational effects, inclusive inheritance and niche construction...

The settlement of subway tunnel due to the rail load after its construction has cause wide concern. But the report of dynamic characteristics of railroad considering uneven settlement has not been reported. Based on a su...
