Strength development of cement pastes with alkali-activated dehydrated sewage sludge

Highlights Geopolymerization recovers the strength of the paste with dehydrated sewage sludge. The addition of NaOH before the water glass optimizes the mixing procedure. Geopolymerization reduces the pore and increases the Si/Ca ratio in the paste. Sludge yield is reduced as the indirect heating reduces the water content. Sludge treatment by the geopolymerization has reduced costs.
Abstract The application of the highly dehydrated sewage sludge (HDSS) with high organic content was discussed through various alkali-activated cement binders. The fresh properties and the strength developments of the cement pastes with 5% HDSS by volume and a liquid-solid ratio of 0.6 mL/g were investigated. Results indicated that the 28-day compressive strength was recovered by the geopolymerization with economic advantages. The costs of such treatment are lower than the landfill by 3.6% or incineration by 30%.
