What is the difference between water stability and concrete? In order to make better use of materials for corresponding engineering construction, Jinan water stabilized concrete manufacturers will analyze this problem.
1. Different concepts, concrete is an artificial stone made of cementitious materials, granular aggregates, water and other admixtures and admixtures in a certain proportion, after uniform mixing, dense molding, curing and hardening, while water stability is achieved by cement consolidated graded crushed stone and compaction.
2. The physical reaction is different. The concrete has fluidity, plasticity, resistance to delamination, segregation and bleeding, and is easy to plaster. The water stability has water resistance and stability.
3. Due to different properties, concrete will produce deformation 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, continuous increase of strain is creep, constant strain, and continuous decrease of stress is relaxation. Cement stabilized macadam has good slab property, its water stability and frost resistance are better than lime stabilized soil, but it often causes dry shrinkage cracks due to water changes.
4. Different uses: important performance of concrete mixture. It comprehensively represents the consistency, fluidity, plasticity, anti stratification, segregation and bleeding performance of the mixture, and ease of plastering. There are many methods and indicators for measuring and expressing the workability of the mixture. In China, the slump (mm) measured by the truncated cone slump cone and the Vibro time (s) measured by the Vibro meter are mainly used as the main indicators of consistency.
"Water stabilized material" refers to adding a certain amount of cement into some building materials (crushed stone soil, crushed stone, etc.) (generally speaking, this amount is less than that of concrete, about 5%, and the cost is also cheaper than that of concrete) to achieve a certain stability effect. Generally speaking, it is used as the base course of buildings or pavement. It has certain strength and waterproof effect. And the stiffness is not very large, with a certain flexibility.
The above is all about the difference between water stability and concrete, and I hope it will be helpful to you. For more information, please continue to follow our website http://www.ycgjglcl.com 。
