| Abstract | ||
| It has done in this research a new investment which it is the use of okra cuplet which we cut before cooking, as binder material for sand casting instead of famous materials used for this purpose such as cement, date -juice, bentonite...the practical experiments proved that compression strength for sand bounded by this material was ( 18.3 - 46.8 N/ mm 2 ) which is high comparing with date juices ( molasses ) (0.1 - 1.99 N / cm 2 ) and bentonite (36-2.3 N / cm 2 ) with same percentages mixtures , the material proved its successes in moulding and the patterns was very easily with fine smoothness without any sides falling when extracting the pattern . The mixture percentages were (3 % - 10 %) in weight, max strength was in (9 %) percentage. Since this material is from waste (actually from rubbish) and it gave such a high compression strength it forms anew strength free binder material. | ||
