The object of investigation is the ceramic material taken from the fortress wall in the city of Girona. The chemical composition of the researched material showed a heightened content of carbon (13.1%) in it, attesting the introduction of fuel into the green body. The heightened content of fuel in the green body promotes porosity formation and uniform sintering inside the ceramic sample. The integral and differential programs of the research samples, which were obtained by means of mercury porosimetry, showed that the total volume of the micropores ranging in size from 10 – 4 to 10 – 8 m is equal to 0.155 cm3/g. The differential distribution of micropores as a function of their size is: 10 – 4 – 10– 5 — 27% (reserve – non-hazardous); 10 – 5 – 10– 6m— 19% (hazardous); 10 – 6 – 10– 7 m — 29%; 10 – 7 – 10– 8 m — 25% (non-hazardous).

西班牙赫罗纳要塞的陶瓷墙材料中的孔隙结构研究

调查的对象是从赫罗纳市堡垒墙中获取的陶瓷材料。被研究材料的化学成分显示其中的碳含量增加(13.1%),证明了将燃料引入生坯中。生坯中燃料含量的增加促进了陶瓷样品内部的孔隙形成和均匀烧结。通过水银孔率法获得的研究样品的积分和微分程序表明,大小为10 – 4至10 – 8 m的微孔的总体积等于0.155 cm 3 / g。微孔随大小变化的分布为:10 – 4 – 10 – 5-27%(储备金–无害);10 – 5 – 10 – 6 m– 19%(危险);10 – 6 – 10– 7 m-29%;10 – 7 – 10 – 8 m – 25%(无危险)。
