Inorganic binder stabilized material refers to the material whose compressive strength meets the specified requirements after adding an appropriate amount of inorganic binder (such as cement, lime or industrial waste residue) and water into all kinds of broken or undisturbed loose soil, gravel and industrial waste residue.
Cement stabilized material refers to the mixture of loose soil, gravel or other aggregates and appropriate amount of cement and water.
2. Different in nature
The rigidity of inorganic binder stabilized materials is between flexible pavement materials and rigid pavement materials, which is usually called semi-rigid materials. The strength increases with age and has certain rigidity; High compressive strength, but low tensile strength; The greater the strength and stiffness, the longer the fatigue life; Dry shrinkage, the volume will change with the change of water content; It has temperature contraction.
Cement stabilizing materials mainly rely on the self-setting and hardening of products after cement hydration, such as hydrated calcium silicate and hydrated calcium ferrite gel, hydrated calcium aluminate and hydrated calcium sulphoaluminate crystal. Cement stone formed after solidification and hardening can closely combine loose materials, thus producing mechanical strength. Secondly, the effect of Ca(OH) produced after cement hydration on loose materials is similar to that of lime stabilized materials.
3. Different advantages and disadvantages
Advantages of inorganic binder stabilized materials: high strength; Good stability; Strong frost resistance; The structure itself is a plate.
Disadvantages: poor wear resistance; It is prone to dry shrinkage cracking; It is prone to temperature shrinkage cracking; Long curing time.
The advantages of cement stabilized materials are high strength and good stability.
Disadvantages: strict construction requirements, high cost and easy cracking.
