Abstract
Soil stabilizer can enhance the soil properties, which can improve ecological environmental problems such as soil erosion and slope instability. This study investigates the water-related and mechanical properties of soil stabilization using a polymer soil stabilizer solution synthesized from vinyl acetate polymer. The water properties test, mechanical properties test, durability test and seed growth test were carried out in the laboratory. Also, the effect of vinyl acetate polymer was verified by field tests. The results revealed that vinyl acetate polymer can enhance the water-retaining property, anti-erosion resistance, strength property and durability of soil, all of which increase with the increase of polymer concentration. At the same time, the polymer also has a certain promoting effect on vegetation growth. In addition, field tests proved that vinyl acetate polymer has good effects on soil engineering. These results could be applied as a reference for vinyl acetate polymer-improved soil engineering.
Highlights
With the development of the social economy, human engineering activities are having a greater and greater impact on the ecological environment, which leads to a series of ecological environmental problems, such as water and soil loss, landslides, dust emission, and so on [1,2,3]
According to the main components, soil stabilizers can be divided into five major categories: lime cement soil stabilizer [5,6,7,8], slag silicate soil stabilizer [9,10,11,12], ionic soil stabilizer [13,14,15,16], bio-enzyme soil stabilizer [17,18] and polymer soil stabilizer [19,20,21,22,23]
Polymer soil stabilizer has become a hot spot of research in soil stabilization materials, because of advantages that include less incorporation, stable curing effect and ecological environmental protection
Summary
With the development of the social economy, human engineering activities are having a greater and greater impact on the ecological environment, which leads to a series of ecological environmental problems, such as water and soil loss, landslides, dust emission, and so on [1,2,3]. The average loss of soil in the United States is 8.7 × 106 kg/km every year [4]. Due to large-scale engineering construction, many bare soil slopes have been formed. These slopes are prone to slope erosion, soil erosion, and other disasters. As a new environmentally friendly soil improvement material, was advanced in developed countries such as the United States and Japan in 1970s. Polymer soil stabilizer has become a hot spot of research in soil stabilization materials, because of advantages that include less incorporation, stable curing effect and ecological environmental protection.
