ЦЕМЕНТИРУЮЩИЕ КОМПОЗИЦИИ НИЗКОЙ ПЛОТНОСТИ ДЛЯ ПРИМЕНЕНИЯ ПРИ НИЗКИХ И ВЫСОКИХ ТЕМПЕРАТУРАХ
A cementitious binder, includes a hydraulic binder in an amount in the range from 50 to 80% by weight of the cementitious binder; a first siliceous based material in an amount in the range from 0.5 to 35% by weight of the cementitious binder, the first siliceous based material having a (SiO2)/(Al2O3) ratio by weight greater than 2.5; a second siliceous based material in an amount in the range from 10 to 25% by weight of the cementitious binder, the second siliceous based material being different from the first siliceous based material and having (a) a (SiO2)/(Al2O3) ratio by weight greater than 10 and (b) a BET specific surface area greater than 5 m2/g; and an aluminum based material in the range from 0 to 10% by weight of the cementitious binder and having a (SiO2)/(Al2O3) ratio by weight lower than 2.5, wherein 0.09<0.28, where AlEFF=molar content of alumina aluminum in the hydraulic binder, and SiEFF=molar content of silica in the first siliceous based material for particles having a size lower than 3 μm+molar content of silica in the second siliceous based material.
