A recent development is the production of low-density SMC. By replacing the calcium carbonate and other SMC fillers with hollow glass microspheres, the density of SMC can be reduced from a specific gravity of 1.9, for traditional SMC, to as low as 1.3, with a small reduction in stiffness. These low-density grades may be applicable to interior ...

The agglomeration of nano-CaCO 3 (NC) is the largest bottleneck in applications in cementitious materials. If nano-CaCO 3 modifies the surface of micron-scale limestone powder (LS), then it will form nano-CaCO 3 /limestone composite particles (NC/LS). It is known that micron-scale limestone is easily dispersed, and the “dispersion” of NC is …
