Description
The core properties of a newly developed core binder based on Manihot esculenta-cement combination was assessed and compared with an imported binder system commonly used in the foundry. The work investigated the properties of the newly developed binder system along side with the properties of UFFA-BSA binder system, which is an imported binder system. The core mixtures were prepared using the same sand; the north bank sand, with grain fineness number of 48.03 AFS, average grain size of 353.50 microns and clay content of 0.8%. The core properties of the newly developed binder system compared well with the core properties of the UFFA-BSA binder system, and can be a good replacement or alternative to the UFFA-BSA binder system. The newly developed binder system is more environmentally friendly than the UFFA-BSA binder system. The UFFA-BSA binder system has a dry compression strength of 4400kPa, and hygroscopy of 0.38%, while the newly developed binder system has a dry compression strength of 4200kPa, and hygroscopy of 0.33%.
