Blending of industrial waste from different sources as partial substitution of Portland cement in pastes and mortars

Binary and ternary combinations of sewage sludge ash (SSA) with marble dust (MD), fly ash (FA) and rice husk ash (RHA) as replacement in Portland cement pastes, were assessed. Several tests were carried out at different curing ages: thermogravimetry, density, water absorption, ultrasonic pulse velocity and mechanical strengths. Pozzolanic effects of the mineral admixtures, densities similar to control sample and improved absorptions when combining waste materials were identified. In general, the compressive strength reaches or exceeds the cement strength class, and blending SSA, FA and RHA (30% cement replacement) increase of strength by 9%, compared to the control sample, was achieved.

Az „iránymutató vízió” szerepe a regionális fejlesztésekben, egy hazai agráripari vállalkozás tapasztalatai (The role of „guiding vision“ on regional developments and experiences of a domestic agro-industrial enterprise)

A szerző tanulmányában külföldi és hazai példák alapján a fenntartható gazdaság kialakítására hoz példákat. Bemutat egy osztrák energiarégiót és egy magyar biodízelgyártó vállalkozást. Mindegyik esetre jellemző, hogy olyan társadalmi-gazdasági környezetet kell teremteni, hogy minden stakeholder a win-win megoldásban legyen érdekelt. _____ Agricultural land ownership and the desirable scale of operation have been the subjects of a plethora of studies. Mainstream research, however, has a tendency not to take the human factor into consideration. The unpredictability of economic policies, uncertainties about EU subsidies, the optimal scale of operation and industry- specific characteristics all constitute a far more exciting and reasonable research topic for the majority. According to literature, social support for the efforts and the existence of a clear “guiding vision” have a crucial role in the success of rural development strategies. Concerning the development of a region or village, it is important to determine whether there exists a leading personality, an example-setting entrepreneur or entrepreneurial group that can act as a fundamental driving force or an initiator in reforming the rural way of life; one that could help preserve positive rural values while nurturing economically successful enterprises. Experience has shown that success can only be built upon partnership and mutual cooperation.
