Nano-modified sol-gel technology for accelerated soil stabilization

A reclamation fill stabilizing composition for accelerated soil stabilization of high water-content heaved marine mud, comprising:

• approximately 15% to approximately 45% weight percent of ordinary Portland cement (OPC);
• approximately 1.5% to approximately 4.0% weight percent of fly ash;
• approximately 1.5% to approximately 4.0% weight percent of slag;
• approximately 1.5% to approximately 4.0% weight percent of waste glass powder;
• approximately 15% to approximately 45% weight percent of potassium silicate;
• approximately 15% to approximately 45% weight percent of calcium oxide;
• approximately 1% to approximately 3% weight percent of nano-silica;
• a combined weight percentage of the OPC, the potassium silicate and the calcium oxide is approximately 90 wt %, and a combined weight percentage of the fly ash, the slag, the waste glass powder and the nano-silica is approximately 10 wt %, based on the total weight of the composition;
• wherein the OPC, fly ash, slag and waste glass powder chemically react with water in high water-content waste soil for hydrolysis polymerization;
• wherein the fly ash, slag, waste glass powder, and potassium silicate chemically and physically lock the water in its formed 3-D alumino-silicate microstructure and provide a gelling geopolymerization function;
• wherein the potassium silicate and calcium oxide chemically and physically trap the water by reacting and bonding with the water and provide a sol-gel immobilization function;
• wherein the nano-silica provides additional crystal nuclei to increase effects of the hydrolysis polymerization, gelling geopolymerization function, and sol-gel immobilization function;
• and
• wherein the reclamation fill stabilizing composition is free of organic substances and acid groups.
