Development of dosage methodology for mortar to plaster

Abstract

Grouting mortar can be defined as a dry industrial product composed of Portland cement or other binder, mineral aggregates and chemical additives which, when mixed with water, form a sticky, plastic and adherent mass, which is used in the construction of wall cladding. Existing dosage formulations are deficient in producing a quality mortar and are often not intended for use. In the ceramic industry a very efficient suspension dosage methodology based on the Brongniart formula is used. In this work, using a scientific methodology, a new mortar dosing procedure was proposed comparing with the standard formula with Brongniart formulation. To validate the methodology the following parameters were determined: consistency, bulk density and suspension volume. The results showed that the mortar with new methodology can be used satisfactorily in the dosage.
