Reinforcing agent for foam cement, and foam cement using same

Abstract

The invention relates to a reinforcing agent for foam cement, and foam cement using the same. The reinforcing agent for the foam cement comprises the following raw materials in parts by mass: 40-60 parts of silica fume, 20 to 40 parts of nanometer crystal whiskers and 1-3 parts of fibers. The nanometer crystal whiskers are used as a core of cement hardening, so the toughness and the strength of the hardened cement are improved; the silica fume plays a role in filling in gaps; and the fibers deeply participate in cement hardening and gap filling on the surface of the nanometer crystal whiskers,and mainly plays a role in preliminary bridging and strengthening of each subsequently obtained part.

Description

technical field [0001] The present application relates to a foamed cement reinforcing agent and foamed cement using the reinforcing agent. Background technique [0002] Foamed cement is cast-in-place or mold-forming of cement slurry through foaming operations, and then cured to form a porous structure with an internal closed form. Because the porous structure itself has the effect of low thermal conductivity, the concrete itself can achieve lightweight and Low thermal conductivity. [0003] However, it should be noted that the current lightening is largely at the expense of reducing the compressive strength, but the low compressive strength directly leads to obstacles in the use range and stability of foamed cement, which affects the development of foamed cement. The promotion of foamed cement; of course, there are some now by adding various substances to improve its compressive strength, but this method directly leads to the complexity of the entire synthesis process, the ...
