STUDY ON PASTES AND MORTARS OF PORTLAND CEMENT WITH REPLACEMENT BY SANITARY WARE

Abstract

In this paper the Sanitary Faience, use as a replacement for portland cement is analyzed. Replacements used were 8, 24 and 40% by weight; the assays used contemplated the evolution of hydration from the first minutes (up to 48 hours) by calorimetry, and from 2 days (to 28 days) by the fixing of calcium hydroxide, water chemically combined, mechanical flexural and compression and porosity. The results showed that with increasing the percentage of replacement, at the earliest ages the effect of dilution overlaps and contrats with the physical stimulation; and at the 28 days all blends showed, as well as physical stimulation, chemistry stimulation, trough of pozzolanic reactivity.
