Análisis comparativo de la concentración de óxidos presentes en el cemento portland y lodos de plantas de tratamiento de agua potable

Oxides concentrations in two types of sludge that came from treatment plants of potable water (PTAP) from Colombian Caribbean region were determined, and were compared with concentrations of these ox-ides in Portland cement type II, in order to decide how feasible is its use in the construction fiel...

Description
Summary:Oxides concentrations in two types of sludge that came from treatment plants of potable water (PTAP) from Colombian Caribbean region were determined, and were compared with concentrations of these ox-ides in Portland cement type II, in order to decide how feasible is its use in the construction field.Research development was made in three stages: 1. Sampling and drying of sludge. 2. Analysis by X-rays fluorescence (XRF), to both types of muds and cement. 3. Statistical analysis of results obtained through a nonparametric test for median comparison. We can conclude in a statistic way exists an impor-tant difference in concentrations of CaO, SiO2, Fe2O3, MgO and Al2O3 of sludges and cement Portland type, however sludge B meets the requirements of the NTC 321 standard “Composición química del cemento Portland (Chemical Composition of Portland Ce-ment)” in concentrations of Al2O3, Fe2O3 and MgO ex-cept in SiO2, in other hand sludge A only meets with percentages of SiO2 and MgO.
