Congreso de Hormig\u00f3n que se realiz\u00f3 en Olavarr\u00eda<\/a>. Las premisas generales que gu\u00edan los nuevos desarrollos a nivel mundial son indiscutiblemente la reducci\u00f3n del impacto ambiental en su fabricaci\u00f3n, a partir del agregado de otros materiales.<\/p>\nEl especialista es coordinador del Centro de Innovaci\u00f3n en Construcci\u00f3n Sustentable de la universidad brasilera, y referente latinoamericano en la tem\u00e1tica. Lo principal en este momento, remarc\u00f3 durante su visita a los laboratorios de la Facultad de Ingenier\u00eda de la UNICEN, es que los desarrollos en ecoeficiencia se puedan aplicar. \u201cMucha gente en la universidad se dedica a hacer papers, que son buenos, pero tambi\u00e9n queremos cosas que la industria pueda utilizar\u201d, se\u00f1al\u00f3. \u201cEn nuestro laboratorio hacemos ciencia b\u00e1sica, si, pero para encontrar alguna soluci\u00f3n espec\u00edfica, es decir, con un objetivo particular en la investigaci\u00f3n\u201d, indic\u00f3.<\/p>\n
El cient\u00edfico defini\u00f3 que esta b\u00fasqueda de volcar los desarrollos cient\u00edficos en el sistema productivo es una cierta obsesi\u00f3n de que esos escenarios sean posibles: \u201cque se puedan utilizar en condiciones normales, y a gran escala, porque los problemas ambientales son de gran escala. No se va a hacer la diferencia en el CO2 con cinco casitas, sino con millones y millones de casitas\u201d, sostuvo.<\/p>\n
En este sentido, Vanderley asegur\u00f3 que \u201cpara nosotros la relaci\u00f3n con la industria es fundamental\u201d. Actualmente, en l\u00ednea con avances como los del Laboratorio de Materiales (INMAT) de la FIO, se busca reemplazos para el cemento de materiales extra\u00eddos en canteras, por otros como desechos de la industria cer\u00e1mica, por ejemplo.<\/p>\n
\u201cLa pregunta es cu\u00e1nto cemento necesitamos reemplazar\u201d, se\u00f1al\u00f3 Vanderley con relaci\u00f3n al desaf\u00edo actual. \u201cHoy en el laboratorio hacemos cosas con un 30 por ciento del cemento que se usa en obras regulares. Y esto tendr\u00eda una reducci\u00f3n del impacto ambiental del 55 por ciento\u201d, agreg\u00f3. \u201cLa huella de carbono se va a la mitad, no es el mismo producto, pero funciona en el 90 por ciento de los requerimientos; no tal vez para un puente\u201d, aclar\u00f3, y asegur\u00f3 que el objetivo es alcanzar en t\u00e9rminos tecnol\u00f3gicos, un material con bajo porcentaje de cemento que permita, tal vez, hacer una casa. \u201cHoy en d\u00eda uno compra una bolsa de cemento y se hace su casa, este tipo de avances no podr\u00eda ir en principio a un mercado de la autoconstrucci\u00f3n, porque requiere cierto control\u201d, subray\u00f3 Vanderley.<\/p>\n
Los impedimentos no surgen solamente desde el aspecto t\u00e9cnico, sino tambi\u00e9n reglamentario. \u201cEs todo un modelo diferente de pensar el cemento\u201d, sostuvo el investigador extranjero. \u201cLa construcci\u00f3n es un sector bastante conservador, las personas quieren hacer una casa para dejar a los nietos\u201d, grafic\u00f3, y aclar\u00f3 que \u201ces bueno que en cierto sentido sea conservador pero por otro lado est\u00e1 el problema ambiental que hay que arreglarlo y si es muy conservador no se arregla nada\u201d, concluy\u00f3.<\/p>\n","protected":false},"excerpt":{"rendered":"
