| titleOfInvention | A kind of modified bagasse retarder and preparation method thereof |
| abstract | The invention discloses a modified sugarcane bagasse setting retarder and a preparation method thereof. The specific method is as follows: firstly, the bagasse is pretreated with sulfite or chlorite, and the lignin and part of hemifibers in the bagasse are removed. element; and then acid hydrolyzed with compound acid under catalytic conditions. The prepared retarder not only contains hydroxyl groups, carboxyl groups, but also functional groups such as phosphoric acid groups. The retardation effect of the modified bagasse retarder was better than that of sodium gluconate at normal temperature (20℃) and high temperature (50℃), and had no effect on the later strength of concrete. Compared with traditional retarders such as sodium gluconate, the modified bagasse retarder has the advantages of low cost, green environmental protection, renewable, simple production process, etc., and has broad application prospects. |
