Abstract
The quality of sand of kut shores is regarded one of the best Iraqi ones which can be used in plumping both ferrous and non- ferrous metals, since it contains high percentage (8 -12%) of clay in comparison with standard world sands which contain percentage of (5 – 20%) of sand weight, that constitutes the main part of the wet sand mold, The addendum of connective and added materials can improve its mechanical properties. The present research studies the effect of connective materials (cement, pentonite ) added materials ( charcoal , phenol, and dates paste ) and the effect of water ratio upon mechanical properties of kut beaches sand. The study has concluded that it is possible to improve mechanical properties of sand used via adding connective materials. The best added percentage has been (4%) for cement; and (2%) for pentonite respectively. As for added materials, the best percentage has been for the charcoal (4%)، and phenol (6%)، whereas the best added water percentage has been (4.5%).the other materials had little effect on the mechanical properties of the used sand .
