Use of granite sludge wastes for the production of ...

2010-9-1 · Mineral limestone was a fine aggregate containing more than 98% CaCO 3. Two types of masonry mortar were prepared. The first series (samples A–D) was obtained simply by replacing some cement with GS; in the second (samples E–G), the limestone filler was increasingly replaced with GS. The composition of the seven samples is shown in Table 2.
