On Friday, September 27, 2019, in the evening, the gate of the AdMaS Center opened to visitors of the popular event Scientists’ Night, this time on the theme of Considering the Planet.

The staff of the individual laboratories, in collaboration with students and family members, prepared several sites reflecting the current research conducted in them. They prepared a demonstration of interesting devices for the visitors, explained their use and attracted two hundred guests in the form of a competition or a practical demonstration. The most popular were, as in past years, 3D printer products, a tomograph contest, a drone simulation flight and, of course, the production of asphalt pavement and playing with Liebherr toy cars.

An electric car, bestowed from E.ON,  was also quite acclaimed and admired.

Both young and old guests gained not only new knowledge, but also many ecological souvenirs, the smallest one a favorite sweet surprise.

FOREIGN TRAINERS IN THE ADMAS ROAD LABORATORY

In August we welcomed 2 foreign trainees to the road laboratory of the AdMaS Research Center.

On August 6, 2019 arrived first student, Arnaud Chuter from France, who is studying civil engineering at EI.CESI University in Angoulême (https://angouleme.cesi.fr/ecoles-formations). Arnaud’s specialization is traffic construction and will stay here until October 25, 2019.

The second student is Riko Sakuda, who came from Japan thanks to the IAESTE organization. Riko is studying at Yokohama National University (Yokohama National University – https://www.ynu.ac.jp/english/) and will be here till mid-October. Her main specialization is urban communications and urban infrastructure.

Both students are very active and have been involved in research activities both at the AdMaS Center and the Institute of Roads. They are also cooperating on solving partial tasks within current research projects. One of them is a project of the Technology Agency of the Czech Republic TH04020154 entitled: “Optimization of the construction, repair and operation of asphalt-concrete sealing cladding”. So far we are very satisfied with both students.

Arnaud Chuter already participated in excursion to the mixing plant in Rajhradice, where he assisted in the sampling of aggregates. In the months of September and October, further professional excursions to cooperating companies or directly to the road construction are planned. Last but not least, there is a plan for a joint discussion of students of the 2nd year of the Master’s program with a focus on traffic constructions.

PREPARATION OF CEMENT CHIPBOARD TEST BODIES CONTAINING ALTERNATIVE RAW MATERIALS

On September 4, 2019, within the ongoing cooperation of the AdMaS Center with CIDEM Hranice, a.s. test specimens of cement-bonded particleboards were prepared and subsequently tested with respect to the assessment of physical-mechanical parameters (bulk density, strength characteristics and flexural modulus), microstructure and combustion heat analysis.

The bodies were manufactured in laboratory. Significantly modified formulas were used for the production of plates, with a view to achieving lower bulk density and improving fire resistance while maintaining minimum standard requirements for utility properties.

Modification of the composition of cement-bonded particleboards was carried out by substitution of primary components (up to 50%) with alternative raw materials (heating slag, waste perlite and dust formed as a by-product during the processing of cement-bonded particleboards).

EXCURSION TO THE ADMAS CENTER IN COOPERATION WITH THE YOUNG ENERGY EUROPE PROJECT

On September 4, 2019, an excursion of participants in the energetics course took place in the AdMaS Center. The course’s target group are young employees under 35 years of age. During different courses they learn how to uncover energy saving reserves, optimize processes or implement energy-saving measures in the company, thereby contribute to better climate protection.

The organizer of the event, the Czech-German Chamber of Commerce and Industry, chose the AdMaS Center not only with regard to its current activities in the area, but also to the technical and technological background of the Center. Supervisors of the EGAR Research Group, Dr. Tomáš Chorazy, Dr. Miroslav Čekon, Dr. Jakub Raček and Ing. Kristýna Velikovská, gradually presented the activities of the center in the field of alternative energy use, eg. Selected technologies and construction elements of buildings leading to energy independence, Gray water recycling for reuse and Recovery of thermal energy from waste water. With respect to the presented topics, there was also an excursion in the AdMaS center and demonstration of individual technologies. The activities of the individual research groups were briefly presented, with an emphasis on the possibilities of comprehensive solutions to problems in the field of construction and resource utilization.

The excursion at the AdMaS Center took place as a practical part of the training in the Young Energy Europe project. This is funded through the European Climate Protection Initiative (EUKI). EUKI is a financial instrument of the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety (BMU). The main objective of the EUKI is cooperation within the European Union that will support the reduction of greenhouse gas emissions and intensify dialogue and exchange of knowledge and experience within Europe under the Paris Agreement.
