The invention provides
solid-waste-based cementing material
coal gangue vegetation concrete and a preparation method thereof. The
solid-waste-based cementing material
coal gangue vegetation concrete is prepared from the following raw materials:
coal gangue aggregate, a
solid-waste-based cementing material,
tap water, water glass, KNO3 and
polyvinyl alcohol building rubber
powder. The
coal gangue aggregate is used as a
structural framework, the
coal gangue powder, the mineral
powder and the
fly ash are used as cementing materials, and the low-alkali equivalent water glass is used as an alkali component, so that the strength requirement is met, and the pH is reduced. A proper amount of KNO3 and
polyvinyl alcohol building rubber powder are doped, so that the workability of the
slurry is improved, and meanwhile, the
slurry has relatively high water permeability and
mechanical property. According to the
coal gangue vegetation concrete, solid waste materials can be fully utilized, particularly, coal gangue can be efficiently utilized, and the vegetation performance requirements can be met through a high-
porosity different-aperture gradient
permeation structure and low
alkalinity of the coal gangue vegetation concrete. The method is suitable for
greening laying of road slopes, river channel protection slopes, squares and parking lots and mine slopes, the slope surfaces can be reinforced, water and
soil loss can be prevented, air can be purified, the
ecological environment of a mining area can be repaired, and ecological balance can be maintained.
