Composition suitable for self-repairing concrete, manufacturing method and application thereof
The present invention relates to a particulate composition suitable for self-repairing concrete comprising limestone-forming bacteria or spores of limestone-forming bacteria and bacterial nutrients dispersed in a lactic acid-based oligomer matrix. The invention also relates to a method of making the particulate composition, comprising the steps of mixing the lactic acid-based oligomer in the liquid phase with limestone-forming bacteria or spores of limestone-forming bacteria and bacterial nutrients, and curing the resulting mixture to form solid particles. The mixing step is preferably carried out in an extruder. The formation of the solid particles may be carried out in an underwater granulator.
本发明涉及一种适用于自修复混凝土的颗粒组合物，其包括分散在乳酸基低聚物基质中的石灰石形成细菌或石灰石形成细菌的孢子和细菌营养物。本发明还涉及一种制造该颗粒组合物的方法，包括将液相的乳酸基低聚物与石灰石形成细菌或石灰石形成细菌的孢子和细菌营养物混合，以及固化所得混合物以形成固体颗粒的步骤。混合步骤优选在挤出机中进行。固体颗粒的形成可以在水下造粒机中进行。
