  • Proposal for a mix design method for coating mortar

    2017-12-20 · Abstract The aim of this study was to propose and analyse an experimental mix design method for coating mortars using artificial crushing sand as fine aggregate. We sought to identify and standardize the mix design procedures so as to fulfil the working conditions for an external mortar coating under the specifications of ABNT NBR 13281:2005 (ABNT, 2005a). The proposed mix design method
