Wall construction |
摘要 |
We have found that if we add a polyhydric phenolic compound such as resorcinol to monohydric phenolic resin/cement systems, we can shorten the gel time sufficiently to use the systems in producing walls. The walls generally are cylindrical and serve to confine a liquid. These systems are especially good for producing large diameter, continuous pipe.
