Abstract
Magnezij fosfatni cementi (eng. magnesium-phosphate cement, MPC) nastaju pri sobnoj temperaturi reakcijom magnezijevog oksida (MgO) i izvora fosfata. Reakcija se odvija brzo, a za kontrolu vremena vezivanja koriste se usporivači poput borne kiseline. Uobičajeno, magnezijev oksid proizveden na visokim temperaturama kalciniranja (1500 – 2000 °C) koristi se za proizvodnju MPC-a. Međutim, ekološki prihvatljivije rješenje može se postići kalciniranjem magnezijevog oksida na nižim temperaturama. Ova vrsta MgO-a se kalcinira na temperaturama od 750 do 1000 °C, što rezultira dovoljnom reaktivnošću. U radu je istražen utjecaj MgO-a kalciniranog na nižim temperaturama, metakaolina, letećeg pepela i sadržaja borne kiseline na obradivost, razvoj temperature i tlačnu čvrstoću MPC paste.
Abstract (english)
Magnesium phosphate cements (MPCs) are formed at room temperature by reaction between magnesium oxide (MgO) and an acidic phosphate source. The reaction proceeds rapidly, and retarders such as boric acid are used to control the setting time. Normally, deadburned magnesium oxide, obtained by calcination at 1500 – 2000 °C, is used to produce MPCs. However, a more environmentally friendly solution can be achieved by using lightburned magnesium oxide. This type of MgO is calcined in a temperature range of 750 – 1000 °C, which results in sufficient reactivity. In this study, the influence of light-burned MgO, metakaolin, fly ash, and boric acid content on the workability, temperature, and compressive strength of MPC paste is investigated.
