Using waste building materials in pavements is one of the goals of transportation sustainable development in the Czech Republic. As part of research projects of the Technology Agency of the Czech Republic, a project was devised, which focused on maximal utilization of waste building materials when constructing pavements. After the initial verification of properties of the recycled aggregate (especially concrete waste building material), the research focus shifted towards the utilization of these waste building materials in cement bound granular mixtures.

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.

Dayu island sea cottage is the most typical carrier of the fish culture in the coastal area of Jiaodong. In recent years, economic development, changes in fishermen's living habits led to a the dismantling of a large number of traditional sea cottages and gradual disappearing of unique Dayu island building materials system comprising of eelgrass roof, local granite stone wall and soil kang chimney. In order to protect the local cultural characteristics so they can be passed down, the paper sorted out the original traditional eelgrass cottage building material system. The project of Century Fishing Village Eelgrass Cottage Resort represents experimentation and innovation on the original material system, forming a novel construction material system. Such a system not only satisfies the requirement of new buildings on thermal insulation, energy and space conservation, but also enhances safety and resistance to wind, erosion. The wide adoption of the new material system in new buildings enhances the technique of integrating traditional construction materials and modern architecture in both form and function, making it an ideal design strategy.

The Stability

The resistance of concrete constructions to high temperatures at present is a much monitored issue for many scientific teams and experts in the stated area. This fact is mainly caused by fatal consequences originating in the case when concrete constructions are loaded by the effect of fire and consequent loss of their load-bearing capacity, for the population and the environment of our planet, in which we live in. The development of society goes hand in hand with the development of new building materials and as a consequence the requirements for building constructions increase which bring about extraordinary strict regulations in the area of fire safety. So, many high, non-traditional or specific constructions originate, e.g. nuclear power plants due to permanently higher demand for transport linkage and many tunnels have originated between European countries as a result. Unfortunately, in this relation the threat of terrorist attacks increases and unexpected natural disasters which also threaten the stability of the mentioned constructions. The objective of the article is to familiarize readers with the results of research concerning the improvement of the resistance of the concrete to high temperatures originated during fire instances.

Suffolk Sheep

Lamb growth performance traits in relation to parental breeding values (BVs) for these traits were evaluated in a purebred Suffolk sheep population in the Czech Republic. The research lasted over 8 years and included 24 886 lambs. Four relevant parental BVs were observed: BV predicted for lamb live weight direct effect (BVLW-DE), BV predicted for lamb live weight maternal effect (BVLW-ME), BV predicted for lamb musculus longissimus lumborum et thoracis depth (BV-MLLT), and BV predicted for lamb backfat thickness (BV-BT). The lamb live weight (LW; kg), musculus longissimus lumborum et thoracis depth (MLLT; mm), and backfat thickness (BT; mm) were assessed at 100 days of age. A dataset was created using the most current parental BVs for each year (2007–2014) and subsequent growth traits of their lambs in the next season (2008–2015). Linear regressions showed an increased tendency when one point in dam BVs was associated with an increase in lamb LW (0.393 kg; P < 0.01 in BVLW-DE and 0.090 kg; P < 0.05 in BVLW-ME), MLLT (0.340 mm; P < 0.01 in BV-MLLT), or BT (0.243; P < 0.01 mm in BV-BT). Lower (but significant – P < 0.01) values on linear regression were detected for sire BVs, when 0.135 kg of LW, 0.217 mm of MLLT, and 0.214 mm of BT corresponded to 1-point increases of BVLW-DE, BV-MLLT, or BV-BT. This was confirmed by ANOVA evaluation, especially for LW and MLLT traits. Maximal differences (P < 0.05) in lamb LW were 1.84 kg or 0.88 kg regarding to dam or sire BVLW-DE groups. Similarly, the difference (P < 0.05) in lamb MLLT reached 0.82 mm in dam BV-MLLT, while 0.57 mm was detected in sire BV-MLLT groups. These results have practical implications for the objectives of selection schemes used in the Suffolk sheep population in the Czech Republic.
