| titleOfInvention | Anti-freezing and anti-cracking concrete and preparation method thereof |
| abstract | The invention belongs to the field of building materials, and particularly relates to anti-freezing and anti-cracking concrete and a preparation method thereof. The product developed by the invention comprises graphene oxide accounting for 1-10% of the mass of the concrete; epoxy groups on the graphene oxide interlayer are replaced by octadecylamine; epoxy groups on the graphene oxide interlayer are substituted by amino; the air bubbles in the concrete are dispersed among the graphene oxide layers; the diameter of the bubbles is 10-100 nm. When the product is prepared, octadecylamine and sodium azide are used for modifying graphene oxide, lithium aluminum hydride is used for processing the graphene oxide to obtain modified graphene oxide, and the modified graphene oxide is added into a concrete mixture to prepare concrete. The product obtained by the invention has good frost resistance and crack resistance, and the service life of the concrete is effectively prolonged. |
