Lightweight wall construction
A low or no fines lightweight concrete mixture. The mixture comprises one part by volume of a cementitious binder, 2-10 parts inert coarse aggregate, a cement additive in an amount of 0.05 to 0.3 % by weight of the cementitious binder and an effective amount of water, the additive including 40-99 %...

Abstract | A low or no fines lightweight concrete mixture. The mixture comprises one part by volume of a cementitious binder, 2-10 parts inert coarse aggregate, a cement additive in an amount of 0.05 to 0.3 % by weight of the cementitious binder and an effective amount of water, the additive including 40-99 % of a viscosity enhancing agent, which in water either dissolves or forms colloidal dispersions, and 1-60 % of an air entrainment agent/surfactant adapted to entrain air when mixed with water and/or pumped. The mixture is particularly suitable for constructing a building panel where a frame is prepared, the front and rear faces being covered by fibre reinforced cementitious sheets and the cavity therebetween at least partially filled with the lightweight concrete mixture which flows in a manner similar to loose fill. |
