Abstract
A multiphase particle has a multiphase structure comprising a first phase and a second phase and has an average particle size of 0.1-100 mm. The multiphase particle has a high bulk strength and a good interface binding power with the hardened cement and is particularly suitable for the toughening application of the hardened cement.
