Lo fundamental cuando se trabaja con cemento<\/a> es ser precavidos durante el fraguado y estar preparados para la aparici\u00f3n de grietas posteriores. Para ello, hay que tener en cuenta una serie de factores clave.<\/p>\n

Contenido de agua en el cemento<\/h2>\n

Mientras m\u00e1s baja sea el porcentaje de cantidad de agua, m\u00e1s fuerte ser\u00e1 la mezcla. Durante el fraguado, esta proporci\u00f3n no debe exceder el 0.5%, por lo que la aplicaci\u00f3n de un plastificante te permitir\u00e1 trabajarlo mejor.<\/p>\n

Lo esencial es\u00a0reducir la cantidad de humedad<\/b>\u00a0para que la contracci\u00f3n no afecte tanto la integridad de los bloques o losas.<\/p>\n

Buena mezcla con productos de calidad<\/h2>\n

Para garantizar las fisuras, la mezcla debe estar balanceada. Los agregados optimizados que son duros, densos y de buen tama\u00f1o eliminan la posibilidad de contracci\u00f3n.<\/p>\n

Por el contrario, los aditivos malos provocan grietas con m\u00e1s facilidad. Intenta evitar elementos adicionales para la mezcla como aceleradores o agregados sucios que exigen m\u00e1s agua.<\/p>\n

La importancia del acabado del cemento<\/h2>\n

Nuestra recomendaci\u00f3n es que distribuyas bien el tiempo haciendo uso de una t\u00e9cnica depurada para llevar a cabo esta etapa tan importante. Trata de no sobrecargarlo mediante los soldados de cemento, ya que esto produce asentamiento, el agua se filtra y se crea una capa de agua en la superficie. No se recomienda terminarlo en ese estado, ya que el l\u00edquido volver\u00e1 al concreto.<\/p>\n

\"Grietas<\/p>\n

Curaci\u00f3n adecuada del hormig\u00f3n<\/p>\n

Para evitar que las placas pierdan agua o se sequen de m\u00e1s, lo m\u00e1s recomendable es curar las losas por algunos d\u00edas. Una vez que se hayan asentado, recurres al m\u00e9todo habitual de delimitarlas con mortero y las mantienes h\u00famedas. Una forma efectiva es cubrirlas con tapetes de algod\u00f3n llenos de agua o rociarlas con un compuesto. La curaci\u00f3n dura un mes y lo ideal es que en ese tiempo el concreto no est\u00e9 sujeto a ning\u00fan tipo de carga que pueda agrietarlo.<\/p>\n
