Sep 1, 2021 · For that purpose, a reference cement mortar is compared to mortars with 10%, 20%, 30% and 40% of cement replacement by weight. Physical, thermal and mechanical properties showed that up to 20% of cement could be replaced by lime mud while maintaining thermal properties of the mortar.

Unlike lime or mud, modern cement doesn't breathe, which is why if you're restoring an old building, it's a disaster. Your house becomes prone to mold and damp, and a concrete mortar slowly and steadily eats away at the ancient stonework, killing the house from within.

Jun 15, 2024 · LM from the paper industry offers a sustainable alternative for concrete, mortar, bricks, and ceramics. Utilizing LM reduces CO 2 emissions, conserves resources, and minimizes environmental impact. Alkali-activated LM enhances strength, with 50% replacement in binders significantly improving compressive strength.

Apr 18, 2022 · Alkali and carbonate-enriched lime mud (LM) is a solid waste produced during alkali recovery in the paper-making industry. In the present work, high-volume LM was upcycled in fly ash and silica fume-blended Portland cement (FSPC), and its positive roles were investigated through hydration kinetics analysis, X-ray diffraction, thermogravimetric ...

To determine the strength qualities of blended concrete, experiments were conducted. The lime mud was used in place of the cement in nominal mixes. The nominal mix considered for the experimental work was of M-10 grade and produced by replacing cement partially with lime mud.

Jan 1, 2011 · Research studies based on cement and aggregate replacement by lime sludge concludes that 10–30% lime sludge is gainfully utilized in sustainable concrete and mortar. Additional prospect for lime...

The lime-mud characterization and its incorporation in cement-based mortars were appraised. The lime-mud effect on fresh and hardened state properties in different mortars formulations was assessed. Workability and mechanical strength were some of …

Finally, the results obtained in the experimental program showed that the 100% hydrated lime replacement mortar by lime mud meets the normative requirements for multiple-use mortars. KEY WORDS: Lime mud; Sustainable mortar; Waste recycling.

Nov 18, 2024 · In the process of water treatment from surface water sources, lime mud as waste is formed. This waste contains CaO, Ca (OH) 2, and CaCO 3. The article proposes a comprehensive method for processing lime mud into high-strength anhydrite cement.

ABSTRACT: This study reports the use of lime mud (LM) in cement-based-mortars. Lime mud is a waste generated in the production of cellulose by the kraft mill process. It is mainly composed of CaCO3, a small amount of magnesium carbonate and other trace minerals.
