Caracterización química y físico-mecánica de cementos adicionados de filer calizo en Venezuela H. Bolognini N. Martínez O. Troconis de Rincón Ingeniería corrosión concreto armado Cemento adicionado En los últimos años en Venezuela, se ha presentado una crisis sobre la demanda, comercialización y producción del cemento, principal material de construcción. En este trabajo se presentará la caracterización química y físico- mecánica realizada a las principales marcas comerciales de cementos adicionados en el país, caracterizándolos de acuerdo a: composición química, finura Blaine, tiempo de fraguado y resistencia mecánica a compresión. Los resultados demuestran que estos cementos no cumplen con los requisitos mínimos establecidos en la norma venezolana para su uso en la elaboración de concreto estructural. 2015 artículo científico 2007-6835 https://www.redalyc.org/articulo.oa?id=427643087003 es http://www.redalyc.org/revista.oa?id=4276 Revista de la Asociación Latinoamericana de Control de Calidad, Patología y Recuperación de la Construcción application/pdf Asociación Latinoamericana de Control de Calidad, Patología y Recuperación de la Construcción, A.
