Problems solved by technology

[0002] With the development of science and technology, people have higher and higher requirements for the living environment, so the standard of traditional building materials to meet the strength of ordinary structures has gradually changed. Cement materials are the most used consumables in construction, and they are also the most needed Improved materials, existing cement materials have appeared cement that enhances thermal insulation performance, cement that solves the problem that cement is easy to freeze during construction in winter, and lightweight cement. However, these are only improvements in single performance and cannot fully satisfy people. needs
