T1 - Use of waste nano-silica rich sludge from photovoltaic production process in self-compacting mortars (SCM) : survey on the replacement of cement and common fillers by waste nano-silica rich sludge (from the PV industry) for the production of SCC mixes used by Kijlstra Betonmortel B.V.

N2 - This progress report presents the second stage of the project. The activities carried out during the last six months (effective date of start: April 2011) of the project can be divided into several parts. First, stable slurries with higher a solid content (26.5% by mass) were designed to be used as liquid additives during the concrete production on site. Second, self-compacting mortars were designed based on the actual self-compacting concrete recipes of the company. The reference SCMs were tested and modified by the replacement of CEM I 52.5 R with the silica-sludge at different levels
(10, 20, 25, 30 and 100% by mass). The fresh and hardened properties of the SCM were determined at 16 hrs, 7 days and 28 days. Additionally, the total chloride content of the SCM were measured by titration method and compared with the calculated values based on the equivalent chloride content of each component in the mix. Finally, three vibrated cocretes (VC) with olivine nano-silica additions were designed and tested to evaluate the potential replacement level of this type of new nano-silica.
