“…After incineration at a high temperature, the components of SiO 2 , CaO, Al 2 O 3 sludge are similar to those of cement [23]. Therefore, the use of sewage sludge ash in the cement industry reduces environmental pollution; reduces the amount of cement required; and has an economic, ecological, and energy saving impact [24][25][26]. When the ash of the sewage sludge is used as an additive to the cement, the pozzolanic activity is lower than that of the cement, determining a lower resistance and a high addition of water, which can be avoided by grinding the ash [27].…”

This paper presents an analysis of the literature that studies the possibility of sewage sludge being used in the cement industry to reduce carbon dioxide emissions from cement production and thus solve the problem of disposing of sewage sludge so that it is no longer stored, avoiding soil pollution with heavy metals, and reducing pressure on the environment. The ash of sewage sludge is a good pozzolanic material, because when it is finely ground, it can be used as a partial substitute for Portland cement. This reduces waste storage costs. Sewage sludge ash was mixed with cement, and it was analyzed to determine whether the paste obtained could be used as a raw material in the cement industry. The presented results are on the hydration characteristics of the sewage sludge ash, the compressive strength of the cement determined after different days, the workability of the cement, and the porosity of the cement paste and the ash.
