Following a TPI techno-economic feasibility study of wood wool slab manufacture in Fiji a request was received for the following tests to be undertaken as a source of data for local assessments of wood wool/cement slab structural properties: (a) Compressive strength of full-sized slab; (b) Deflection under uniform loading to failure; (c) Failing load of the dowel/wood wool slab joint; (d) Shear strength of full sized slab. These tests, with the exception of shear, were undertaken by TPI in consultation with the Overseas Division of the Building Research Establishment. Shear testing was undertaken by private consultants under BRE(OD) funding. Methods used and results obtained, together with additional tests including the assessment of fire propagation and wetting expansion and drying shrinkage, are given in this report. Also included as Appendix I is a technical assessment of the minimum chemical and other raw material inputs required to produce wood wool/cement slabs to meet British Standards from P. caribaea. Comments were obtained from BRE(OD) and are given in Appendix III
