1. High technology. Using common concrete, finished in 3 minutes. Key technology-HJ composite addition agent is made of many kinds of raw material which is easy to buy according to a certain proportion can using longterm. It's easy to control it who bought the equipment from our factory with the prescription uneasy to leak out.

2. Wide resources of raw material. The main raw material is concrete and sand, using local material with low costs, high profit.

3. Technics simpleness. Using HO composite addition agent can make the concrete and sand together without model. It can finish through the closed pressing with equipment suspensory moving.

4. Low costs. The cament have the strong competitive advantage in the market, using common concrete without models, saving money and labour, high output.

5. Undemanding request for production condition. The facility work shed can as the workshop, needn't storage. The fence can pile up out of the door. Low request for worker, the country women can do it.

6. Wide using of the technics. It's also can products continental component, using common concrete instead of sulful-alminate, can forming immediately without molds; Broken the tradition technics that must use the molds, overcome the joint and airhole.

Though the test by The country building materials industry house constructs for the material quality surveillance and examine Center indication that every tech index can meet the standard of our country.
