Description : |
The Rockwool – RWP is a man-made inorganic fiber produced mainly from basalt (igneous) rock, mainly destined for industrial landfills, generating negative environmental impacts. The aim of this research was to find the pozzolanic potential of Rockwool waste to its valorization as a pozzolanic material. The greatest innovation of this work was to analyze the possibility and the effect of replacing Portland cement with Rockwool waste in mortars, with the aim of making the method viable and sustainable. The results of the tests carried out show that the waste of Rockwool is classified as class II A - non-inert (not dangerous), it has a characteristic of amorphous solid and showed a potential development of pozzolanicity at an advanced age. The granulometric distribution curves exhibited a multimodal character and the presence of a fine fraction for the two milling times around 3 μm, in addition to a very fine fraction around 0.2 μm for a 2-h grinding.
