Beton se dobiva mijesanjem cementa, vode i agregata. U novije vrijeme nemoguce je zamisliti izradu betona bez aditiva i mineralnih dodataka. Mineralnim dodacima za beton smatraju se fino zrnato dispergirani materijali, koji mogu biti dodavani u beton u relativno velikim kolicinama s obzirom na masu cementa (20-100%).…
Research was carried out in order to contribute to the understanding of mechanism of highspeed bonding of calcium aluminate cement (CAC) and development of fast setting and fast curing cement materials. Also, the influence of lithium carbonate on the speed of bonding has been studied. Early initial and high final soli…
This paper examines the influence of alkali metals chlorides, alkaline earth metals chlorides and chlorides of transition elements on setting time of the calcium aluminate cement (CAC) with purpose of manufacturing new cemente composites. Commercial calcium aluminate cement (CAC) 40, manufactured by Istra Cement Inter…

Polyurethane foams, a class of materials renowned for durability and ease of production, also represent a significant fire hazard through their inclusion in such ubiquitous consumer goods as carpet underlay, mattresses, and furniture.These foams ignite easily, burn at incredible rates, and release enormous amounts of…
The goal of this work was to test the resistance to general and pitting corrosion of dental implants made form stainless steel and titanium alloy. Tests were conducted in artificial saliva and in artificial saliva with Curasept antiseptic in ratio 1:1. To simulate oral cavity conditions as close as possible, measuring…
Organic photovoltaics have shown much promise as an alternative photovoltaic technology for application in low-cost, large-scale and flexible solar cells. The application of metal oxides in organic solar cells (OSCs) and the impact of the properties of metal oxide/organic hetero-interfaces on cell performance have att…
Cette thèse a été menée dans l'équipe interaction ion-matière du laboratoire collision agrégat et réactivité (LCAR). Elle s'inscrit dans le contexte général de la radiothérapie et en particulier celui de l'étude de l'origine de la radio-sensibilation induite par l'interaction entre un rayonnement ionisant et certaines…

This chapter discusses the physical properties of rare-earth modified Bi4Ti3O12 (BT) system that are investigated. High-density ceramic samples are obtained from the solid-state reaction method. The structural and microstructural properties are studied from the x-ray and scanning electron microscopy techniques, respec…
This chapter describes mechanical and microstructure properties of oxide scales on ODS alloy coupons, with a composition of Ni-20Cr-5A1-1.5Y2O3 (wt.%) that are processed by combined mechanochemical bonding (MCB) and ball milling, compacted by uniaxial pressing and subsequently exposed to thermal cyclic oxidation at 11…
Tin oxide (SnO2) is a well-known wide band-gap n-type semiconductor with potential applications in devices such as gas sensors, dye based solar cells, etc. Lately, rare-earth doped nanoparticles attract special attention due to their catalytic and gas sensing behaviour. This chapter illustrates the synthesis of Dyspro…
CuFe2O4 is synthesized by microwave irradiation and conventional processing. In addition, microwave H-field annealing is conducted in order to investigate the effect of a magnetic field on tetragonal CuFe2O4. The sample synthesized with microwave E-field irradiation is cubic CuFe2O4, has a small saturation magnetizati…
Due to its excellent thermal resistance, mechanical and chemical stability at both room and elevated temperature, silicon carbide (SiC) is an attractive material for nuclear fuel cladding or catalyst supports. The control of the porosity during its elaboration is the key deciding factor for such applications. This cha…
Non-isothermal combustion experiments of different additive amount of biomass char (0,20,40,60,80,100 wt%) at heating rates of 5, 10 and 20 K/min were conducted by synthesized thermogravimetry analyzer(STA409PC) from room temperature to 900°C in air atmosphere. The changes of combustion characteristic parameters of pu…
Graphene nanosheets (GNS) in conductive ink are being given attractive interest due to their growing application in the printed electronics industry. This chapter aims to develop and characterize a graphene nanosheet–polyaniline (GNS–PANI) nanocomposite for conductive ink fabrication. Graphite oxide is prepared from g…
A titania nanotube (TNT) array structure of 120nm in average nanotube diameter were grown on the surface of Ti6Al4V by electrochemical anodization and then filled with a cholesterol lowering statin drug Simvastatin. A thin layer of polycaprolactone (PCL) polymer was coated over the TNTs loaded with drugs to enable sus…
This chapter presents results of the study of chemical and mineralogical composition and technological properties of basalts and tuffs, explored on the territory of the Republic of Belarus and establishes the possibility of their use as components for producing ceramic tiles for interior wall facing. The introduction…
Wet synthetic process is an effective and facile method at low cost, environmentally benign process for easy scaling-up and then used for fabrication of multi-utility devices. Self-assembling of nanobrick leads to architecture framework with new functional properties which help to make its vast applications as nanodev…
