Cement-based recycled concrete
The invention provides cement-based recycled concrete, and relates to the technical field of building materials. According to the invention, the waste granite stone powder and the silica fume are simultaneously doped to replace part of cement, and the ratio of the waste granite stone powder to the silica fume is adjusted, so that the waste granite stone powder and the silica fume can play a good synergistic effect and a complementary effect under the condition of reducing the use of cement raw materials; therefore, the problems of low activity of the doped granite waste stone powder and cracking in a curing stage caused by hydration volume expansion of the silica fume are solved, and the mechanical property and durability of the cement-based recycled concrete are effectively improved; and the performance of the cement-based recycled concrete meets the use requirements, the reutilization rate of the waste granite is effectively improved, and resource reutilization is realized.
本发明提供了一种水泥基再生混凝土，涉及建筑材料技术领域。本发明通过同时掺入废弃花岗岩石粉和硅灰替代部分水泥，并调整废弃花岗岩石粉与硅灰的比例，在减少水泥原料使用的条件下，废弃花岗岩石粉与硅灰能够发挥良好的协同作用以及“互补效应”，从而克服了掺杂花岗岩废弃石粉活性低的问题和硅灰水化体积膨胀导致的固化阶段开裂的问题，进而有效改善了水泥基再生混凝土的力学性能和耐久性能；使水泥基再生混凝土性能满足使用要求的同时，有效提高了废弃花岗岩的再利用率，实现了资源再利用。
