What's the difference between concrete, concrete and water-stable materials? Is it the same?
Concrete is the same as concrete. Concrete is the abbreviation of concrete, but there is a difference between water-stable materials and concrete. The differences are as follows:

1, with different meanings:

(1) Concrete, abbreviated as "concrete (tóng)": refers to the general name of engineering composite materials in which aggregates are bonded into a whole by cementing materials. 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 and stirring water (including admixture and admixture) in a certain proportion, which is widely used in civil engineering.

(2) "Water-stable materials" are definitely not concrete additives, and concrete additives are generally called "additives" to improve some properties of concrete.

2. Different uses:

(1) The most important performance of concrete mixture. The properties of the mixture, such as consistency, fluidity, plasticity, anti-delamination, segregation and bleeding, and easy plastering, are comprehensively shown. There are many methods and indicators to measure and express the workability of mixture. In China, slump (mm) measured by truncated cone method and Weibull time (sec) measured by Weibull instrument are mainly used as the main indicators of consistency.

(2) "Water-stable material" refers to adding a certain amount of cement to some building materials (gravel soil, gravel, etc.). Generally speaking, this amount is not as high as concrete, and the cost is about 5%, which is cheaper than concrete) to achieve a certain stabilizing effect. Generally speaking, it is used as the base of buildings or pavements. It has certain strength and waterproof effect. Moreover, the stiffness is not great, and it has some flexibility.

3. Different in nature:

(1) Concrete will be deformed under load or temperature and humidity, mainly including elastic deformation, plastic deformation, shrinkage and temperature deformation. The elastic deformation of concrete under short-term load is mainly expressed by elastic modulus. Under long-term load, the phenomenon of constant stress and increasing strain is creep, while the phenomenon of constant strain and decreasing stress is relaxation. The volume deformation caused by cement hydration, carbonation and cement stone dehydration is called shrinkage.

(2) Cement-stabilized macadam has good plate-like performance, and its water stability and frost resistance are better than lime-stabilized soil, but it often causes shrinkage cracks due to moisture change.
