High-performance permeable concrete

   
   

The present invention relates to an improved high-performance permeable concrete obtained by spreading and compacting a mixture which comprises 1,500-1,850 kg/m.sup.3 of aggregates; 320-400 kg/m.sup.3 of Portland cement; 28-35% of the cement (90-140 kg/m.sup.3) of water; 2-5% of the cement (6-20 kg/m.sup.3) of a pigment; and 3-10% of the cement (10-40 kg/m.sup.3) of charcoal dust, 7-15% of the cement (22-60 kg/m.sup.3) being substituted for particulates of blast furnace slag, and having the compressive strength of 120-300 kgf/cm.sup.2 and the permeability coefficient of 2.times.10.sup.-2 cm/sec or more. The permeable concrete according to the present invention is environmental friendly and has excellent strength and permeability.

La actual invención se relaciona con un concreto permeable de alto rendimiento mejorado obtenido separando y condensando una mezcla que abarque 1.500-1.850 kg/m.sup.3 de agregados; 320-400 kg/m.sup.3 del cemento de Portland; 28-35% del cemento (90-140 kg/m.sup.3) del agua; 2-5% del cemento (6-20 kg/m.sup.3) de un pigmento; y 3-10% del cemento (10-40 kg/m.sup.3) del polvo de carbón de leña, 7-15% del cemento (22-60 kg/m.sup.3) que es substituido para los particulates de la escoria del alto horno alto, y teniendo la fuerza compresiva de 120-300 kgf/cm.sup.2 y el coeficiente de la permeabilidad de 2.times.10.sup.-2 cm/sec o más. El concreto permeable según la actual invención es amistoso ambiental y tiene fuerza y permeabilidad excelentes.
