SHORT DESCRIPTION:

• The system described here, developed at the Forest Products Research and Development Institute, Philippines, uses hollow soil-cement blocks, which contain a certain amount of beach sand and agricultural wastes, such as rice husks, sawdust, wood chips and coconuttrunk particles.

• The blocks (10 x 20 x 40 cm with 3 rectangular holes) are made in wooden hand moulds. The raw mixture, with a moisture content similar to that for common soil cement blocks, is filled into the mould, tamped and levelled, after which the blocks can be demoulded and placed on their narrow sides for moist curing (about 10 days).

• Wall construction is the same as for concrete hollow blocks, and extremely rigid constructions are achieved by filling the cavities with steel reinforcement and concrete.
