Construction of crystallization nucleation and network crosslinking structure in bamboo scrap/magnesium oxychloride composites via nano-SiO2

The problem of utilizing substantial bamboo residual waste while also improving the quality of building composites was addressed by preparing bamboo scrap/magnesium oxychloride composites using bamboo scraps as a reinforcing material and magnesium oxychloride as a matrix. However, problems remain, s...
