Example Embodiment

[0012] Example 1

[0013] A calcium-enhanced bentonite used for the treatment of railway and highway roadbed, according to its volume percentage 3 The components are: saponification residue: bentonite: fly ash=1:0.1:0.1.

Example Embodiment

[0014] Example 2

[0015] A calcium-increasing bentonite used in the treatment of railway and highway roadbeds has a composition of saponification residue: bentonite: fly ash=1:0.1:0.6 according to its volume percentage.

Example Embodiment

[0016] Example 3

[0017] A calcium-enhanced bentonite used for the treatment of railway and highway roadbed, according to its volume percentage 3 The components are: saponification residue: bentonite: fly ash = 1:0.1:0.3

[0018] Preparation method of calcium-increasing bentonite:

[0019] 1. Feeding

[0020] Including drying, mixing, and transporting the saponification residue to the raw material storage yard. Take 750 cubic meters of saponification residue and put it into the drying field, pile it up according to the ratio of length, width and height of 30:25:1, stir and dry with bamboo rakes to accelerate water loss. After drying until the moisture content in the saponification residue is less than 30%, it is put into a mixing tank and stirred until the particle diameter of the raw material block is less than 2 cm. The unqualified return to the drying link.

[0021] 2. Neutralization, washing and draining

[0022] It includes four steps of adding sulfuric acid, washing with wa...

Description

technical field [0001] The invention belongs to chemical building materials, in particular to a calcium-increased bentonite used for treating railway and highway subgrades. Background technique [0002] With the rapid economic growth in the Bohai Bay area, the demand for infrastructure construction such as railways and highways is also increasing. These infrastructure constructions must first solve the difficult problems of increasing load strength and preventing ground subsidence on weak foundations. Subgrade settlement of railways and highways is mainly caused by factors such as subgrade water loss, insufficient compactness and uneven force. Therefore, it is required that the building materials of railway and highway foundations should have water absorption to form water retention; they should have expansion force to generate tension force; they should have cementation to generate binding force and increase load strength. Tianjin Dagu Chemical Co., Ltd. is an important c...
