Abstract: A downhole treatment fluid made up of a binding composition and a proppant, the binding composition including an aluminosilicate source, a metal silicate, an alkali metal activator. The binding composition may form a coated particulate or an aggregate with the proppant and provides strength-enhancing properties. The binding composition has easy handling properties facilitating on-the-fly preparation and downhole injection procedures. Furthermore, the binding composition has a low strength-hardening temperature and so may strength-harden in the presence of downhole temperatures.
