Background technology
Currently, cement industry has had many globalization features.Global cement industry is estimated to increase by 3% every year.At present with
It cement consumption and is increased with the velocity-stabilization for approaching development of world economy, it may be said that cement is produced in developing country or southern exposure
Industry, and the development in developed country then has some cycles.It is generally believed that emerging market is positioned at the Middle East, north
Non-, Asia, Latin America and eastern Europe, also African some areas.Scholarly forecast：In the long run, emerging market cement demand
It will increase, and U.S.'s demand will substantially go up.After 2017, either emerging market or the U.S., opportunity are unprecedented, wherein
The potentiality maximum of India, Pakistan, Indonesia and Nigeria.So Cement Market needs to invest.
Enterprise recently at home, Africa, the Middle East, the ground such as Asia accepted a plurality of 5000t/d to 10000t/d manufacture of cement
The production line of line project, such production capacity needs the cement silo of capacity bigger to meet production requirement.Therefore, a large amount of diameter 15m
Above concrete cement silo is widely used.It is seen according to international, domestic current research applicable cases, diameter 15m or more
Concrete silo use prestressing technique, safety, economy will preferably be ensured.
Prestressing technique has the function of the characteristics of improving structure uses, the bearing capacity and crack resistance of enhancing structure, while can
With resources such as saving steel and concrete.A certain number of ring orientation prestress reinforcing bars are arranged in concrete storehouse wall, for offsetting
The hoop tension that storing, temperature action etc. are generated in bulkhead, the generation or development in control bulkhead crack.Rear tension prestress technology
It has been broadly divided into and has bonded and two kinds of systems of soap-free emulsion polymeization.Bonded prestress system uses bellows reserving hole channel, concreting
Presstressed reinforcing steel is penetrated after the completion, then tensioning, be in the milk.Prestressing without bondn system is that oiling is plastic on single presstressed reinforcing steel,
It is mounted in framework of steel reinforcement before concreting, presstressed reinforcing steel can slide in plastics duct when tensioning, be not necessarily to grouting procedure.
So, how prestressing technique to be easily applied to concrete cement silo is then that engineering construction side needs to be concerned about
The problem of.

Following steps：
S1, so that bulkhead is in light condition, remove the coherent mass and dust of bulkhead inner and outer wall, ensure the inner wall of bulkhead and outer
The flatness of wall reaches 85-95%；
S2, the raw material of polymer mortar layer is separately added into blender in proportion, 30-40min is stirred under 25-30 DEG C of constant temperature,
Obtain mixture A；The raw material of lean concrete grout layer is separately added into blender in proportion, 30-40min is stirred under 25-30 DEG C of constant temperature,
Obtain mixture B；
S3, the inner wall that the mixture A that step S2 is obtained is coated on to bulkhead, side apply selvedge idle running bulkhead, and mixture A coatings are uniform
After continue dally bulkhead, object A to be mixed bulkhead inner wall solidification after, stand 30-60min；
S4, the outer wall that the mixture B that step S2 is obtained is coated on to bulkhead, side apply selvedge idle running bulkhead, and mixture B coatings are uniform
