And Behavior

Artificial sintered aggregate produced by self-firing is one of the few building materials, which can be produced with only fly ash. If the character of the fly ash is optimal, no other additions are needed. However, not every fly ash has optimal composition. Quality of fly ash then influences composition of the mix, technological parameters and quality of produced aggregate. Parameters influence the process of self-firing, strength of granules during the phases of drying process, ignition and burning under given underpressure on an agglomerating bed. This often influences correct setting of proportion of combustion material and reduces quality of aggregate. The paper evaluates fly ash produced in the Czech Republic by both high temperature and fluidized bed combustions. Their granulometry, specific surface, bulk weight, structure, chemical composition and behavior at higher temperatures up to the melting point are evaluated.

All the world as well as our conference faced to the pandemic in 2021. Therefore, the 24th International Conference on Building Materials, Products and Technologies (ICBMPT 2021) had to be postponed from the usual date in June to the new date 29th September to 1st October 2021. The participants appreciated our choice to organize the conference again in the beautiful town of Telč in the Czech Republic, which is popular with many tourists, because it belongs to the cultural heritage under protection of UNECSCO. Despite the difficult situation, the organizers from the Research Institute for Building Materials collected 23 interesting papers among research workplaces in the Czech Republic and abroad. The conference brings not only interesting presentations, but also it creates a platform for scientific discussions and proposals of new mutual projects. The main topics of ICBMPT 2021 were: Inorganic binders, Composite materials, Building materials based on secondary raw materials and Technology and test methods in building industry. Also, several keynote speakers were attracted to contribute to our conference. Besides the conference program, there was a possibility to take part in the specialized workshop Healthy buildings with many interesting topics, among others asbestos treatment and biodeteriogens in building environment. We would like to thank all the participants for their valuable contribution to the conference. We would like to express our gratitude to the reviewers for their time, valuable recommendations and constructive evaluation, in order to guarantee high quality of all the papers. We are looking forward to the next conference in better times! List of Scientific committee, Editors, are available in this pdf.

Mutual Agreement

Sharing of the risk and liability is one of the most important functions of construction contracts. Proper sharing of the risks and liability between the parties of construction contract has a rather big influence on efficiency, quality, and probability of arising disputes between the parties of construction contract in construction projects. A lot of risk exists during the fulfillment of construction projects. One of those risks is the risk of defects of building products. The question of the liability of the parties of construction contract for inappropriate quality of the construction production caused by a bad quality of building products mainly depends on sharing of the risk of defects of building materials in the construction contract. Some aspects of the mentioned risk and liability of the parties of the construction contract might be set by mutual agreement in the construction contract. The other aspects are regulated by imperative norms of the law and the parties of construction contract have not a right to change those imperative conditions of sharing of risks and liability. The article deals with sharing of risk and liability for supplying building products of an improper quality for construction, taking in to account conditions of construction contract, legal regulation and behavior of parties of a construction contract. A tree of forming the alternatives of liability is presented in the article. Liability for supply of defected building products arises not only for parties of a construction contract. The producer (supplier) of building products is responsible for this as well. Variations of liability of the producer (supplier) depending on construction contract conditions are analyzed. A matrix of liability of the producer (supplier) of building products is presented in the article.

Abstract This paper contributes to the sociological theorization of religious lifestyles in consumer culture, analyzing one of its most important identity markers: style. Based on a three-year comparative ethnographic research project into five convert Buddhist organizations in France and the Czech Republic, it finds that style is expressed through aesthetics with its adornment practices apparent in everyday life materializations of Buddhist symbols. The stylistic dimension is also found in practitioners’ attitudes towards Buddhism, as they may use the discourse of taste. Moreover, Buddhist style stands for the collective, coherent, and systematic emotional patterns expressed in Buddhist symbols, individual and collective experiences, and the ethics and behavior they display in everyday life. The paper also explores how this style is adapted to the educated, middle-class, city-dweller practitioners and how it respects dynamics of consumer culture with its emphasis on identity, style, and values of well-being, authenticity, and personal development.

First technological process, which ceramic producers of ceramic products use for their future ceramic product is mining process. Mining methods, Transport methods and processing methods are basic technological processes. The process of drying, firing and shaping of brick products are specific. Babylonian gardens, Hagia Sofia, are one of the most beautiful churches that has ever been built. The great Wall of China, medieval castle Malbork from northern Poland not far from Gdansk`s bay which resembles small town, Skyscraper Chrysler Building in New York are the outstanding brick creations in the world. All of these buildings have one thing in common and that is material from which they were built. The material is brick, one of the simplest, the most beautiful, the most universal and the oldest building product which is known for moreover than 10 000 years [1]. Brick association of Czech and Moravia, nowadays unites 6 regular members with 19 plants where are created fired building materials. Furthermore it unites 7 associated members who ensure various services for brickmakers and 7 honorary members. Producers, members of brick association represent 92 % of Mason material capacity in the Czech Republic and 100 % of fired roofing tile capacity.

 Genetic diversity was detected in 11 varieties of triticale registered in the Czech Republic by means of polymorphism of prolamin proteins using the PAGE ISTA method. The polymorphism of prolamin proteins allowed the differentiation of the individual triticale varieties in 2002 and 2003 harvests. On the basis of Dice’s calculations of coefficients of similarity we discovered, in parallel with the uniform genotypes, genotypes with sister prolamin spectrums with a different percentage of participation in the respective years. A uniform spectrum was detected in the following varieties: Disco, Kolor, Lamberto, Marko, Presto, Sekundo, Ticino and Tricolor; Kitaro and Modus were dimorphous varieties. In 2003 three sister prolamin lines appeared in the variety Gabo and in 2004 only two. In 2003 a 5% admixture of a foreign genotype was detected in the variety Marko. Typical of the unknown genotype was the gliadin block Gld 1B3, which is the marker of rye translocation T1BL.1RS, gene Sr31 with resistance to black rust, higher cold resistance and lower baking quality of the wheat. The prolamin proteins of triticale grain are suitable for the detection of the genetic diversity and for the assessment of varietal authenticity and purity in seed samples of triticale varieties registered in the Czech Republic.
