Use of $Na_2SiF_6$ powder and ester liquid as hardeners with Na silicate was studied. In each binder system, studies were conducted on the setting characteristics of sands bonded with different binders and hardener levels. Sand mixures were analyzed by using SEM and x-ray diffraction to determine the nature of the bond formed. Experiments were conducted to assess permeability, friability, knockout, and thermal properties of the sand mixts. $Na_2SiF_6$ and ester containing 90 diacetin and 10% triacetin were hardeners for Na silicate bonded sands.
