“…It should be noted that smaller and regularly formed air bubbles produce higher compressive strengths than coarser and irregularly formed air bubbles [ 46 ]. Mechanical properties are strongly influenced by the distribution of pores within the hardened aerated slurry [ 47 , 48 ]. The spherical and distributed nature of foams in Figure 12 b with higher air content led to a viable level of compressive strength which was not lower than that provided by the aerated slurry shown in Figure 12 b with lower content of irregularly-shaped air bubbles.…”

Cementitious composites, including ferrocement and continuous fiber reinforced cement, are increasingly considered for building construction and repair. One alternative in processing of these composites is to infiltrate the reinforcement (continuous fibers or chicken mesh) with a flowable cementitious slurry. The relatively high density of cementitious binders, when compared with polymeric binders, are a setback in efforts to introduce cementitious composites as lower-cost, fire-resistant, and durable alternatives to polymer composites. Aeration of the slurry is an effective means of reducing the density of cementitious composites. This approach, however, compromises the mechanical properties of cementitious binders. An experimental program was undertaken in order to assess the potential for production of aerated slurry with a desired balance of density, mechanical performance, and barrier qualities. The potential for nondestructive monitoring of strength development in aerated cementitious slurry was also investigated. This research produced aerated slurries with densities as low as 0.9 g/cm3 with viable mechanical and barrier qualities for production of composites. The microstructure of these composites was also investigated.

“…When this material is mixed with cement, the alkalies released by the hydration of the cement are often adequate for the activation of GGBFS. Activation of GGBFS may be achieved by direct mixing with lime water and used for the production of super-sulfated cement by adding sulfates (Olorunsogo and Wainwright, 1998). The use of slag significantly reduces the permeability of the soil mixture.…”
