Otpornost materijala na bazi metalurškog cementa na dejstvo kiselina / Resistance of CEM III/B based materials to acid attack
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
Cementni materijali u poljoprivrednim i drugim industrijskim objektima izloženi su dejstvu kiselina. Zbog toga vek konstrukcija zavisi od trajnosti maltera ili betonskih elemenata u agresivnoj sredini. U radu je predstavljena ...
The influence of silica fume and curing regime on some properties of concrete
(Revista Romana de Materiale/ Romanian Journal of Materials, 2014)
The investigation of posibilities of concrete structure modification by silica fume to improve concrete properties was presented in this report. Percentage of silica fume in regard to cement varied between 0% and 20%. ...
Investigation of high temperature behavior and sintering mechanism of fly ash based concretes
(Procema SA, 2014)
Four types of refractory concretes were studied at various temperatures ranging from ambient to adopted maximal 1400 degrees C. The concretes had same matrix composition: K concretes were based on corundum aggregate; B ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (HSLA) steel on low cycle fatigue
(Croatian Metallurgical Soc, Zagreb, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
