Abstract

Adjuvant for acceleration of set of hydraulic binder according to the main patent FR. 1,566, 705, in which wood fibre is added after the mineralisation step, to obtain a lightweight concrete. The wood fibre is pref. soaked in formates solution containing 2 - 98% formate. The formates can be mixed with potash, acetate, aluminate, carbonate, lignosulphate, lignosulphite permanganate, stearate triethanolamine or their derivatives.
