Embodiment 1

[0020] Weigh 10g of acrylamide, 9g of polyvinyl alcohol, 5g of sodium dodecylbenzenesulfonate, 8g of calcium chloride and 68g of water to prepare an aqueous solution.

[0021] Initiator (NH 4 ) 2 S 2 o 8 / NaHSO 3 (0.0015g / 0.0015g), after mixing, immediately mix with 350g of cement and 4550g of crushed soil (removing organic matter such as grass roots), and compact the soil into bricks with an ordinary non-burning brick machine, then 280w microwave radiation for 5min. The soil modified building material is obtained.

Embodiment 2

[0023] Weigh 8g of acrylamide, 8g of polyvinyl alcohol, 4g of sodium dodecylbenzenesulfonate, 10g of calcium chloride and 70g of water to prepare an aqueous solution.

[0024] Initiator (NH 4 ) 2 S 2 o 8 / NaHSO 3 (0.0012g / 0.0012g) was added to the above-mentioned prepared aqueous solution, and immediately mixed with 400g of cement and 4500g of crushed soil (removing organic matter such as grass roots) after mixing, and compacted the soil with an ordinary unburned brick machine. After the bricks were irradiated with 119W microwave for 8 minutes, the soil modified building materials were obtained.

Abstract

The invention provides a soil modifier and an application method thereof. The soil modifier is an aqueous solution consisting of acrylamide, polyvinyl alcohol, sodium dodecyl benzene sulfonate and calcium chloride with certain mass fractions. In actual usage process, the soil modifier is uniformly mixed with an initiator and soil according to a certain mass ratio, and the soil is compacted for forming and is irradiated by microwaves for a certain time, so that a soil modifying building material is obtained. The soil modifier and the application method are simple, and additionally the soil modifier takes mine tailings, waste soil and other solid wastes as application targets and is beneficial for environment protection.

Description

technical field [0001] The invention relates to a soil modifying agent, in particular to a preparation and application method of the soil modifying agent used in the production of building materials. technical background [0002] Soil modifiers have been widely used engineering materials in developed countries in Europe and America decades ago. Its role is to solidify the ordinary soil into a solid overall plate, which was originally used for the foundation of roads and squares. Compared with the traditional method, the use of soil modification technology has solved the problem of "hydrophilicity" of the soil, and transformed the soil from "hydrophilic" to "hydrophobic", improving its water stability and improving its water stability. It fundamentally overcomes the damage caused by "water immersion" to the base of traditional structures. Not only that, after the soil modification technology is adopted, the main material is changed from traditional sand and gravel materials...
