  • The performance of ultra-lightweight foamed concrete

    Apr 29, 2021 · where C is the mass of the cementitious materials added (kg/m 3) and A is the mass of the aggregates (kg/m 3).According to this formula, 60 kg/m 3 of fine lightweight aggregate required a cementitious material content of 240 kg/m 3, for all mixtures.. Four dosages were used to study the influence of nanosilica on the performance of foamed concrete: 1.25, 2.5, 5, and 10 wt.-% of cement.

  • Effects of slag type and curing method on the performance

    Nov 30, 2020 · 1. The strength, expansion, and transport properties of expansive concrete were weakened by the incorporation of pure slag at 50% cement replacement by mass due to its slow hydration. 2. The use of slag with gypsum was found to enhance the performance of slag-blended concrete by promoting slag hydration.
