In the broken or original loose soil, enough cement and water are mixed, and the mixture obtained by mixing is compacted and cured, and when its compressive strength reaches the specified requirements, it is called cement stabilized soil.
The mixture with qualified strength obtained by cement stabilizing fine-grained soil can be simply called cement soil, cement sand or cement fragments according to the type of soil used. The mixture obtained from cement stabilized medium-grained soil and coarse-grained soil meets the requirements in strength, which depends on the raw materials used, and can be called cement macadam, cement gravel and so on.
Cement concrete: refers to the general name of engineering composite materials combined by cement, sand, stone and other water. Generally speaking, the term concrete refers to cement as cementing material and sandstone as aggregate; Cement concrete, also known as ordinary concrete, is made by mixing cement and water (with or without additives and additives) in a certain proportion, stirring, molding and curing, and is widely used in civil engineering.
Cement stabilized soil and cement stabilized granular materials:
Salts containing a large number of silica tetrahedrons and alumina octahedrons have high stability under normal conditions, and the composition and structure of these minerals have gelling ability. The generated gelled substances are wrapped on the surface of clay particles, and together with the hydration products of cement, the clay particles are condensed into a whole, which is called good integrity. ?
Granular soil refers to natural soil materials such as clay sand and clay gravel and artificial soil materials such as steel slag, cinder, slag and gravel with similar particle composition, and the content of sand, gravel and fine particles (particle size 0.074 mm) is ≤15%. General cement (seven kinds of cement in the current national standard) stabilized granular soil has the characteristics of high strength, good water stability and rapid strength development. As a structural material, it is more and more widely used on the pavement of high-grade highways.
