The semi-hydrated gypsum used is 2CaSO4·H2O, also referred to as bassanite, crystal is in micro-needle shape, like gypsum illusion,
It is colourless or white in bulk, streak white, like glassy lustre.
And silicon ash can then fill hole in solidified earth body, further promote the intensity for solidifying the soil body.Specifically, sticky rice syrup
Solidify in the soil body that there are certain holes with the formation such as semi-hydrated gypsum, quick lime and white lime, be unfavorable for the stabilization of solidified earth,
And silicon ash is then able to enter hole, substantially reduces the pore-size of solidified earth, improves compactness, and then improves and solidify the soil body
Intensity.Meanwhile silicon ash can also be filled the gap between loess, further promote the density of loess metope.
And water-reducing agent is able to ascend the mobility of metope repair materials, controls the shrinkage etc. of metope repair materials.Pass through
Above-mentioned substance and aforementioned proportion can guarantee that the sticky rice syrup being prepared is capable of forming that intensity height, resistance to erosion, barrier properties are good to be consolidated
Change the soil body, then impaired metope is repaired well.The embodiment of the present invention uses water-reducing agent for routine in the prior art
Water-reducing agent.
Further, fibrous material can prevent metope from cracking after repair, can reduce loess metope and fall off, so that repairing
Complex has tensile strength well, and can further improve the hole between loess particle and closely knit problem.
Further, fibrous material is plant fiber, it is preferable that for any one in hemp cut, shredded coconut meat and wheat straw.Using upper
