Abstract: A method of producing cement or concrete, comprising the step of adding fly ash to the cement or concrete at the production stage, the fly ash containing lime and reaction products from the reaction occurring between lime and sulphur oxides in connection with the desulphuration of flue gases. To avoid the disadvantageous effects of calcium sulphite and entringite reactions and to increase the used amount of fly ash containing desulphuration waste, the calcium sulphite is oxidized by hydrogen peroxide either before the production of cement or concrete or during the production.

Abstract: UN METODO PARA PRODUCIR CEMENTO U HORMIGON, QUE COMPRENDE LA ETAPA DE AÑADIR CENIZAS VOLANTES AL CEMENTO U HORMIGON EN LA FASE DE PRODUCCION, CONTENIENDO LAS CENIZAS VOLANTES CAL Y PRODUCTOS DE REACCION PROCEDENTES DE LA REACCION QUE TIENE LUGAR ENTRE CAL Y OXIDOS DE AZUFRE EN CONEXION CON LA DESULFURACION DE LOS GASES DE COMBUSTION. PARA EVITAR LOS EFECTOS DESVENTAJOSOS DEL SULFITO DE CALCIO Y LAS REACCIONES DE LA ENTRINGITA Y PARA AUMENTAR LA CANTIDAD UTILIZADA DE CENIZAS VOLANTES QUE CONTIENEN RESIDUO DE DESULFURACION, EL SULFITO DE CALCIO SE OXIDA MEDIANTE PEROXIDO DE HIDROGENO, BIEN SEA ANTES DE LA PRODUCCION DE CEMENTO U HORMIGON O DURANTE LA PRODUCCION.
