SAND TOO COARSE When the sand is too coarse the cement cannot fill the void space between sand grains the affect on the final product? Open course surface texture Jeading to increased permeability higher potential for efflorescence SAND TOO FINE Sands which are finer than ideal tend to produce tiles which are less strong Jess durable than expected These mixes require high water demand increasing the chance oflock splay and may lead to surface bubbling. Very important, the void content between particles affects the amount of cement required for the mix. The following slide has an illustration that will further explain. leading lock
