preparation example Construction

[0026] A preparation method of the active powder soil solidifying agent is as follows: Weigh the bonding material, aluminosilicate material, active material and activator by weight percentage, and grind them until the Blaine specific surface area is 4600-8800cm 2 / g, mixed thoroughly, then placed in a reaction kettle, and activated at a temperature of 60-100°C for 1-5 hours to obtain the soil curing agent. Preferably, the activation temperature is 70-80° C., and the activation time is 2-3 hours. Even more preferably, the activation temperature is preferably 74-76°C.

[0027] An application of an active powder soil curing agent, the weight ratio of the soil curing agent to the dry soil to be solidified is 0.015-0.03:100, and the two are fully mixed and applied to water conservancy project construction, soft foundation treatment, backfilling and land reclamation , basic construction, road construction, landfill, sand control and dust fixation and other fields. Further preferab...

Abstract

The invention relates to an active powder soil solidifying agent as well as a preparation method and application thereof. The active powder soil solidifying agent comprises the following components in percentage by weight: 4%-8% of binding materials, 76%-89% of aluminosilicate materials, 4%-12% of active materials and 3%-7% of exciting agents. The active powder soil solidifying agent disclosed by the invention is reasonable in component proportion, obtains the raw materials locally, is convenient, advisable, simple in production process, low in energy consumption, low in cost, wide in trial range on different soil, high in solidifying strength and stable in solidified soil layer property; the prepared soil solidifying agent is applied to a site construction process, simple and easy to operate; compared with the traditional construction process, the prepared soil solidifying agent is less in usage amount, creates better social benefit, economic benefit and environment benefit and plays a certain environmental protection role by utilizing waste residue coal ash, gangue, iron ore slag and the like.

Description

technical field [0001] The invention relates to a novel soil curing agent in the construction field, in particular to an active powder soil curing agent and its preparation method and application. Background technique [0002] Soil stabilizer is a new type of energy-saving and environmental protection engineering material synthesized from various inorganic and organic materials for curing various soils. After it is mixed with the soil, it changes the engineering properties of the soil through a series of physical and chemical reactions. It can fix a large amount of free water in the soil in the form of crystal water, which reduces the surface current of the soil micelles, and the electric double layer adsorbed by the micelles Thinning, electrolyte concentration increases, particles tend to coagulate, volume expansion further fills soil pores, and under the action of compaction work, the solidified soil is easy to compact and stabilize, thereby forming an overall structure an...
