| titleOfInvention | A composite curing agent for improving the early compressive strength of heavy metal polluted sediment |
| abstract | The invention provides a composite curing agent for improving the early compressive strength of heavy metal polluted bottom mud, which consists of 0.5%-3% liquid curing agent, 6%-20% cementitious material and 0.5%-5% The composition of the early strength agent, the preparation steps of the liquid curing agent are: 1) dissolving sodium styrene sulfonate and allyl thiourea or allyl cysteine in deionized water, stirring, and insulated at 50-80°C for 10- 40min to obtain solution A; 2) dissolving acrylic acid and mercaptopropionic acid in deionized water to prepare material B; 3) weighing ammonium persulfate and dissolving it in deionized water to prepare material C; 4) mixing material B and C Add dropwise to 1) solution A respectively, and add C material dropwise for 5-10min first, and keep warm for 1-5h to obtain solution D; 5) adjust the pH of solution D to 4-6 with sodium hydroxide solution, and replenish water to The solid content is 20‑50 wt%. The curing agent can effectively improve the compressive strength of the sediment. |
