The mixing method is the investigation of the characteristics of alkali-activated cement paste (AACP) with slag and silica fume (SF) of 1: 1. The basic mixing method is ASTM C305, which is defined as 1st-cycle. There are three factors considered in this experiment; (i) the addition of mixing time (2nd-cycle), (ii) the concentration of activator dep...

Le Deep Soil Mixing est une technique d’amélioration de sols dont la part de marché devient non négligeable. Les progrès technologiques dans le domaine permettent aujourd’hui d’envisager la réalisation d’ouvrages permanents. L’utilisation structurelle du matériau sol-ciment n’est cependant pas encore réglementée comme le béton avec l’Eurocode 2, ni...

Vlhkost ve stavebních konstrukcích představuje problém, který ovlivňuje významným způsobem nejen živostnost staveb, ale má také negativní vliv na izolační schopnosti použitých materiálů a v neposlední řadě nepříznivě působí na kvalitu vnitřního prostředí budov. Přestože byla v minulosti tomuto tématu věnovaná zvýšená pozornost, současný stav budov ...

Manufacturing Review
In this study, nanoindentation tests were used to evaluate the mechanical properties of spark plasma sintered Ti based composites containing 5, 10 and 15 wt.% Nb2O5, targeted for potential use as biomedical material. Nanoindentation tests were performed on the samples using indenter loads of 20 and 100 mN, while the microstructures were characteriz...

Few studies of cryogenic treatment were focused on nonferrous alloys, such as magnesium alloy. In this work, the effect of cryogenic treatment (77 K) before extrusion on microstructure and mechanical properties of ZK60 alloy was investigated. The results showed that many fine G.P. zones were formed during the cryogenic treatment and then grew to sh...

Alpine skis have changed dramatically in the last century. Long and straight wood skis have evolved into shorter lengths and now contain a plethora of modern materials. Shaped skis have become the norm. Today’s skis also offer a variety of waist widths and shapes to cater to specific uses. By studying how skis have evolved, it is possible to gain i...

The electrification of automotive powertrains in recent years has been driving the development of internal combustion engines towards reduced volumes with higher power outputs. These changes place extreme demands on engine materials. Engineers employ the computer-aided engineering approach to design reliable and cost-effective engines. However, thi...

It is believed that the structure and properties of parts fabricated by additive (i.e., non-stationary) manufacturing are slightly worse compared to hot pressing. To further proceed with improving the quality of Fused Deposition Modeling 3D-printed parts, the &lsquo / UHMWPE + 17 wt.% HDPE-g-SMA + 12 wt.% PP&rsquo / composite feedstock fabrication ...

The optimization of sport equipment parts requires considerable time and high costs due to the high complexity of the development process. For this reason, we have developed a novel approach to decrease the cost and time for the optimization of the design, which consists of producing a first prototype by 3D printing, applying the forces that normal...
