Problems solved by technology

[0003] The grouting method is one of the main treatment methods to deal with formation cracks. The currently used travertine geological grouting materials are mainly cement-based materials, that is, silicate materials. As travertine geological grouting materials, when repairing cracks, smooth Seam running, insufficient filling, etc., resulting in low utilization rate of grout, large amount of waste, and difficult construction, so it cannot fundamentally solve such problems
Moreover, in the process of underwater pouring, it is very easy for the slurry to be diluted by water, destroying the consistency state of the slurry, seriously affecting the coagulation process of the slurry, and even causing the slurry to fail to condense to form stones, which makes it difficult to guarantee the treatment effect. Increased construction difficulty and economic cost

preparation example Construction

[0036] The present invention also provides a kind of preparation method of travertine geological grouting material, comprises the following steps:

[0037] Mix glutinous rice pulp, silica fume, travertine soil, quicklime, slaked lime, hemihydrate gypsum and water reducer to form travertine geological grouting material.

[0038] Specifically: first, prepare glutinous rice slurry: pregelatinize glutinous rice flour and water, the pregelatinization time is 20-40 minutes, and the pregelatinization temperature is 80-90°C. Using the temperature and time of the above pregelatinization can ensure that the glutinous rice and water are fully gelatinized to obtain glutinous rice pulp, and avoid the structure of the glutinous rice pulp being damaged due to insufficient gelatinization or excessive gelatinization of the glutinous rice.

[0039] Then cool the glutinous rice pulp to 20-30°C, and then ensure that the glutinous rice pulp can well interact with silica fume, travertine and other ...

Embodiment 1

[0050] This embodiment provides a travertine geological grouting material, which includes 250 parts of glutinous rice pulp, 25 parts of silica fume, 400 parts of travertine soil, 60 parts of quicklime, 60 parts of slaked lime, 400 parts of hemihydrate gypsum and 10 parts of water reducer. The mass percent concentration of the glutinous rice pulp is 2%, and the moisture content of the travertine soil is 5%.

[0051] The present embodiment provides a kind of preparation method of travertine geological grouting material:

[0052] First, the glutinous rice flour is mixed with water for pregelatinization, the pregelatinization time is 20 minutes, and the pregelatinization temperature is 80°C. Then the obtained slurry is cooled so that the temperature of the glutinous rice slurry is 20°C.

[0053] Then the first mixture obtained after the prepared glutinous rice slurry is stirred and mixed with silica fume and the travertine, the stirring time is 1 minute, and the stirring speed is...

Embodiment 2-5

[0058] The travertine geological grouting material provided by embodiment 2-5 is basically consistent with the composition of the travertine geological grouting material provided by embodiment 1, the difference is that the proportioning of each raw material is different, the preparation of the travertine geological grouting material provided by embodiment 2-5 The method is basically the same as the preparation method of the travertine geological grouting material provided in Example 1, except that the specific operating conditions are changed.

Abstract

The invention relates to the field of building materials and particularly relates to a grouting material for travertine geology, a preparation method of the grouting material and a process for remedying an underwater travertine geologic crack. The grouting material for travertine geology can be used for remedying the underwater travertine geologic crack and comprises the ingredients in parts by weight: 250-310 parts of polished glutinous rice pulp, 25-35 parts of silica fume, 400-425 parts of travertine, 60-110 parts of quicklime, 60-110 parts of slaked lime, 400-500 parts of semi-hydrated gypsum and 10-18 parts of water reducer. The grouting material for travertine geology has relatively good fluidity and adhesion property and can resist a scouring action of flowing water, thus, slurry can normally coagulate under the action of flowing water, meanwhile, the slurry can be tightly attached to two walls of each pore, the crack remedying effect is enhanced, the global stability of the crack is improved, and a concretion has relatively high strength and durability.

Description

technical field [0001] The invention relates to the field of building materials, and in particular to a travertine geological grouting material, a preparation method thereof and a process for repairing underwater travertine geological cracks. Background technique [0002] With the passage of time, more and more ancient buildings, rock soil bodies and underwater landscapes in natural scenic spots have suffered a large number of damage phenomena such as cracks and broken blocks due to natural factors or man-made damage, seriously affecting their landscapes. value and historical research value, it needs to be reinforced, and there are still many underwater landscapes and rock and soil bodies that need to be repaired. However, ordinary cement mortar repair materials have problems such as long setting time, difficulty in underwater pouring, easy defects in the strength of the grout stone body, and great damage to the ecological environment, which greatly limit its application in ...
