Example Embodiment

[0027] Example 1

[0028] The soil stabilizer formula is composed according to the following weight component ratio: industrial purity 95% concentrated sulfuric acid 91kg, turpentine 5kg, phenol ether OP-10 emulsifier 3kg, xanthan gum 0.6kg, carrageenan 0.4kg; apply this stabilizer to Beijing Consolidation experiment of sandy sub-clay at the road base of a village in Chaoyang District. The optimal water content of the measured soil is 14%, and the actual water content is calculated as 15%; the stabilizer is 0.02% of the soil weight, and the P.O22.5 ordinary Portland cement is mixed 3%; the average daily temperature is 25℃ , Consolidation thickness of solidified soil is 200mm, construction area is 4000M 2 , Soil liquid limit is 30%, plastic index is 9; road mechanized construction is adopted, compaction is greater than 97%, sample curing box is cured for 6 days, and unconfined compressive strength is 2.86Mpa measured after immersion for 1 day.

Abstract

The invention discloses a soil chemical stabilizer formula and an application. The formula is characterized by comprising raw material components in parts by weight: 70-93 parts of sulfuric acid, 3-30parts of rosin oil, 1-6 parts of wetting agent, 0.5-1.7 parts of dispersing agent and 0.3-1.5 parts of thickening agent. Soil and the soil chemical stabilizer are stirred evenly for compaction and maintenance under the condition of the optimum water content, wherein the addition amount of the soil chemical stabilizer accounts for 0.01-0.04% of the soil; the soil chemical stabilizer can be used independently, while a little of concrete or lime needs to be added in many cases; the construction of the stabilizer adopts traditional equipment, and the construction method is the same as the conventional process. The soil chemical stabilizer has the characteristics of low cost, excellent performance and environmental friendly materials, and can be widely applied in the fields, such as subgrade construction, water conservancy construction, country roads, temporary sites, low cost road pavements, wall building and brick making and the like.

Description

technical field [0001] The invention belongs to the technical field of chemicals for soil stabilizing treatment, in particular to a chemical for stabilizing and treating compacted soil with optimal water content and its application. Background technique [0002] In the field of building materials, the most widely used and widely used material is soil, which is the basis for supporting our human beings and all biological activities. While enjoying the nature that the soil brings us happiness and hope, human beings also have to face some troubles and disasters, such as strong winds and dust, muddy roads, landslides, foundation collapses, collapse of dams and buildings, mudslides and earthquake etc. Some of these troubles and disasters are inevitable, while others can be reduced through human efforts, and most of these hazards are related to unstable soil. Stabilizing the soil, reducing disasters and preventing damage have long been valued by human beings. Before 2000, our a...
