..., it is a powerful machine learning tool when sufficient attention is paid to the specification of the regression model so that it is informed by previous knowledge. This chapter demonstrates the application of multiple linear regression to the modelling of the relationship between the residual flexural strength...

In establishing “unity in diversity,” I believe talent management could finally make the transition into a more mature field of academic...

It is not the first pandemic of the twenty-first century...

... prepared and cured for different periods. A range of tests was conducted to investigate the properties and microstructure of the pastes, including compressive strength, X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, energy dispersive X-ray and thermogravimetric...

... variations in the microstructure described by porosity, pore size distribution and consequently strength. The macro- and micro-scale investigation was performed on mortar exposed to alternated climate conditions concurrently with laboratory-cured material. The bulk properties determined in this study...

...The aim of this work is to investigate the effects of elevated temperatures upon the properties of concrete. A stress-strain relationship, and strength behaviour are studied. The test programme has been carried out using a stiff compression testing machine equipped with an electrical furnace...

...Apart from strength and durability, deformation and flexural ductility are important parameters to be considered in the design of structural elements of High Performance Concrete. Change in the mechanical properties of HPC is very important in understanding structural behaviour. Research and codal...

... the weak properties of concrete like tensile strength, resistance to cracking, limited ductility and strain capacity. This enhancement will modify the failure mode and improve both the shear and torsional strength of plain concrete. This paper reviewed the previous studies on the torsional strength...

...In designing composite structures it is necessary to verify the following three sections: normal, diagonal and horizontal. The behavior of composite steel – concrete structures with external profiled reinforcement is directly dependant on deformability and strength of contact. Contact behavior...

...The strength of reinforced concrete masonry walls formed with mortared stretcher bonded concrete ‘H’ blocks, core filled with high slump grout and centrally reinforced with unrestrained reinforcement is investigated. Codes of practice consider masonry walls with unrestrained reinforcement...

...In strengthening reinforced concrete beams with CFRP sheets, failure can be caused by the crushing of concrete in compression, rupture of plate in tension, peeling-off or concrete cover delamination. In the first two failure modes, the ultimate strength of structural members can be easily...

... are conducted. It is established that flowability of concrete mixes, their slump loss and strength properties of concretes depend both on the length of side oxyethylated chains of binary copolymers and on their molecular weight. It is shown that these copolymers as high-performance superplasticizers ensure high...

...Despite the proven economic, environmental and technical benefits, long-term strength development and durability performance, the utilisation of PFA (pulverised-fuel ash, fly ash) in many countries concrete remains at a moderate level. Wider use of PFA in concrete is inhibited by a number...

...Strength is the basic concrete's qualitative index that defines reliability and economy of concrete and reinforced concrete products and constructions. It is not fully examined due to its complexity. Authors of this paper expound their opinion and researches over the question above. This paper...

The possibility of prediction of strength in real structures using an equivalent age approach is discussed. The hydration of high volume fly ash concrete is delayed slightly. Its final degree of hydration...
