Polymer soil stabilization with cement production, which can be as high as 1.25 tons of carbon dioxide per ton of cement. Polymer treatments modify the size, shape, and cohesion of soil aggregates by changing the interactions between soil particles. Because polymer-soil interactions occur on the surfaces of soil particles, the amount of surface area in the soil (in other words, its dominant particle size) is of great importance. Polymers have only weak interactions with the large sand- and silt-sized particles of soil, while they bond directly to finer clays. Although polymers mainly interact with the clay fraction of soils, they do change the
Parent material heave and churn soil material. Chemical weathering: the principal agent is percolating rainwater charged with carbon dioxide from the atmosphere. Parent material becomes hydrolyzed by the acidic solution to produce minerals and to release cations. Parent material Parent material is the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. Soils typically inherit a great deal of structure and minerals from their parent material, and, as such, are often classified based upon their contents of consolidated or unconsolidated mineral material that has undergone some degree of physical or chemical weathering and the mode
