<p>The hydraulic cement is comprised of Portland cement clinker, gypsum and low water demand organic material. The Portland cement clinker is comprised of three fractions of particles bound with low water organic material, of which the first fraction has particle dimensions comprised between 0.05 and 10 microns, the second between 10 and 30 microns, and the third between 30 and 80 microns, the first fraction participating in a proportion comprised between 15.3 and 34.3 % of the mass, the second between 37.2 and 77.4 % and the third between 4.2 and 19.6 % of the mass. With these three fractions of Portland cement clinker there is added pure clinker with particle sizes larger than 80 microns and in a proportion comprised between 0.1 and 4.8 % of the mass.</p> |
