It is known that when sodium silicate solution and an acid are mixed, a gel is sooner or later formed. The speed of gelation depends on a number of factors. The fundamental factors on which gelation depends are- (l) The concentration of water glass (2) The concentration of acid (3) Agitation (4) Temperature In this work, these four factors were kept as constant as possible. It is also known that the presence of NH3 considerably reduces the time of set. In this work, the effect of CH3 NH2, which is closely related to NH3, was studied. The effect of methyl ammonium chloride was also studied.
