Abstract
The invention discloses a micro-expansion and anti-cracking super-early strength double-component geopolymer grouting material. The micro-expansion and anti-cracking super-early strength double-component geopolymer grouting material is prepared from mineral mixture slurry and an active exciting agent solution, wherein the content of the mineral mixture slurry and the active exciting agent solutionis as follows in parts by weight: 70 to 80 parts of the mineral mixture slurry and 20 to 30 parts of the active exciting agent solution; the mineral mixture slurry is prepared from the following components: slag micro-powder, fly ash, silica fume, metakaolin, steel slag micro-powder, quartz sand, staple fibers, an additive and water; the active exciting agent solution is prepared from the following components: sodium silicate, sodium hydroxide, sodium metasilicate and sodium sulfite. The micro-expansion and anti-cracking super-early strength double-component geopolymer grouting material disclosed by the invention has higher early strength and better later-period mechanical property and toughness, has micro-expansion and no shrinkage cracks, and also has good corrosion resistance at the same time; the micro-expansion and anti-cracking super-early strength double-component geopolymer grouting material can have extremely strong durability under various bad climatic environments and is anideal grouting material.
Description
technical field [0001] The invention relates to a geopolymer grouting material, in particular to a micro-expansion anti-crack super early strength two-component geopolymer grouting material. Background technique [0002] The concept of geopolymer was proposed by the French Davidovits in 1978, it is a kind of AlO 4 and SiO 4 An inorganic polymer with a three-dimensional network structure composed of tetrahedral structural units, the chemical formula is Mn{-(SiO 2 ) zAlO 2}n·wH 2 O, amorphous to semi-crystalline, belongs to non-metallic materials. Geopolymer materials have a series of remarkable performance characteristics: (1) high material strength, fast hardening; (2) good acid and alkali corrosion resistance; (3) good impermeability; (4) excellent durability; (5) )Green. [0003] The grouting material is the main substance that fills and consolidates the fractures and pores in the formation, and it is the key to achieve water blocking or reinforcement. Geopolymer gr...
