Summary:One of the best ways to understand the improvement in tensile or compression strength properties of sodium silicate binder systems is to take a microscopic view of the binder bridge of the cured sodium silicate. Fig. 3 is an example of a binder bridge of a weak system with round grain silica sand. At the contact points of the individual sand grains, the binder has formed a cup-shaped impression where the adjacent sand grain was removed.
