Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the examples given by the inventor.

[0013] The novel soil solidifying agent of the present invention is mixed and ground to Blaine's specific surface area of ​​400-900m with the components of the following weight ratio 2 / kg made into:

[0014] Cementitious material: 78%~80%

[0015] Basic catalyst: 10%~15%

[0016] Surfactant: 1%~1.5%

[0017] Slag: 3.5%~11%

[0018] In each component of the material, the water content should be less than 2%;

[0019] The cementitious material includes calcium silicate, calcium aluminate, and one or more combinations of aluminoferrite;

[0020] The basic catalyst is composed of natural gypsum, fly ash. Gypsum content is measured as SO in hydraulic cementitious materials 3 The content is controlled within the range of 4.0±0.2%;

[0021] The surfactant is sodium silicate, copper sulfate, sodium sulfate and FDN raw materials, which are compounded...

Abstract

Disclosed is a new soil curing agent, using cement, alkali catalyst, surface active agent and mine refuse as the raw material, mixing and grinding the components by reasonable weight ratio until the specific surface area is 400-900m2 / kg,. The invention has high consolidating strength, good water stability and resistance to coldness, small deformation and wide range of application, its consolidating principle is: In the time of making the basic structure of soil have no dispersion like lightly touching with interface, make use of the potential activity of minerals like silicate and aluminates to make the interface form stead multi-assemble, advancing the essence of soil particle interface, making it have higher strength and water stability. The curing agent can make effect both on interface and in the soil unit, further developing the theory of soil consolidation in the general temperature.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and construction materials, in particular to a hydraulic cementitious material MBER (A Material Becoming Earth into Rock) applied in civil engineering and construction engineering, that is, a novel soil curing agent. Background technique [0002] At present, the cementitious material used in civil construction engineering is mainly Portland cement. This cementitious material uses sand and gravel as aggregate, which has a poor solidification effect on soil and has high requirements on water quality. When sand is used as aggregate and Portland cement is used as cementitious material to mix concrete, in order not to affect the performance of concrete, in addition to the special requirements for sand and water quality, the soil in the sand should be mixed as much as possible. Clean up. This is not only time-consuming and labor-intensive, but also in areas with no sand or gravel or poor wate...
