The invention describes improved mortar compositions that can reach compressive strength values up to six times more than the obtained ones by conventional mortars at the first hours of setting, as well as up to three times more at 28 days of setting. Cementitious materials, such as Portland cement and clinker of Portland cement were refined in a high energy mill until reaching the greater fineness possible (100% < 10,um) to obtain a material with greater mechanical resistance by compression that those that are reached with normal cement. The compositions of the invention containing the refined cementitious material as well as refined and suitably distributed sand, develop compressive strengths substantially higher (greater to 100 MPa).
Cette invention concerne des compositions de mortier améliorées qui peuvent atteindre des valeurs de résistance à la compression jusqu'à 6 fois supérieures à celles obtenues par les mortiers traditionnels après les premières heures de durcissement, et jusqu'à 3 fois supérieures après 28 jours de durcissement. Des matériaux à base de ciment, tels que ciment Portland et du clinker de ciment Portland, raffinés dans un broyeur à haute énergie jusqu'à atteindre la plus grande finesse possible (100 % < 10 µm), jusqu'à produire un matériau et une résistance mécanique à la compression plus grande que celle atteinte avec du ciment normal. Ces compositions contenant un tel matériau à base de ciment raffiné ainsi que du sable raffiné et distribué de façon appropriée, développent des résistances à la compression sensiblement supérieure (jusqu'à 100 MPa).
