CONSTRUCTION CEMENT AND METHOD FOR THE PRODUCING THEREOF
摘要
<p>The cement comprises a belite clinker (A) and a second component (B) made up of particles of at least one ceramic material. Preferably this second component has a particle size under 100 nm, and is present in a ratio between 0.2% and 15% by weight of the belite component (A). This cement has the advantages of conventional belite cement and also has better mechanical properties. The process for obtaining a building cement comprises the steps of:
(a) producing a belite cement (A) clinker from low lime content fly ash by adding lime (CaO) to the clinker until reaching a CaO/SiO 2 molar ratio greater or equal to 2 and hydrothermally treating the mixture;
(b) grinding the obtained clinker; and
(c) adding to the clinker a second component (B) made up of at least one ceramic material with a particle size under 100 nm.</p>
