Abstract
Description
technical field
[0001] The invention relates to a lightweight polyurethane plastic paving material, in particular to a novel lightweight polyurethane paving material using fly ash as a filler. Background technique
[0002] Fly ash is a kind of pozzolan-like mixed material formed after pulverized coal is burned at high temperature. It is a powdery substance collected by a dust collector after a certain fineness of pulverized coal is burned in a boiler (1100-1500°C). , is a highly dispersed aggregate of fine particles, gray or off-white in dry state, non-cohesive, fly ash with high water content is gray-black, due to surface tension, most of the fly ash particles are hollow particles Beads; the surface of the microbeads is uneven, extremely uneven, and the micropores are small; some of them are connected due to collisions in the molten state, forming rough surfaces and honeycomb particles with many corners, and their particle sizes are concentrated in 10-1000μm, about Account...
