Pozzolanic properties of residues of sugar industries (second part)
Results of studies conducted in lime pozzolana pastes are introduced in this paper. The pozzolana was sourced from Sugar Cane Baggasse Ash (CBC) and Sugar Cane Straw Ash (CPC). The hydration of this binder was carefully monitored by means of instrumental

The thermal properties of mortars modified by the effect of combining polymers and SCMs
The thermal performance of the building materials is relevant to any use of composite materials, especially in relation to constructions where it is desirable to have high specific heat, low thermal conductivity and slight or no decrease of stiffness ...
