8 cze 2023 · This study presents a comparative analysis of laboratory-produced masonry mortars, compacted using four different methods, namely manual tamping and tapping and mechanical jolting and vibration, all of which are specified in masonry and cement-specific standards.
Test methods for mortar characterization including ASTM C1324 as well as alternatives and other historical methods were reviewed to compare the mortar qualities relevant to mortar characterization and techniques used to examine such properties.
7 lip 2018 · From our experience, the most accurate method to determine the binder nature of an historic mortar is the wet chemical analysis which comprises of dissolution of the binder in acid followed by aggregate separation (Alvarez et al. 1999; Middendorf et al. 2004; Van Balen et al. 1999).
1 gru 2021 · In this study, the influence of three types of mixers (planetary mixer, drum mixer and horizontal shaft mixer) and different mixing times (120, 180 and 240 s) and their relationship with the properties in the fresh and hardened state of industrialized mortars of multiple use were evaluated.
6 sie 2021 · By treating high-resolution microphotographs with chromatic analysis software, we can obtain valuable information about the features of the aggregate and the binder, the presence of organic and inorganic admixtures (such as fibres, hairs, plants, etc.), and the roughness of the mortar and its pathologies (Fig. 1).
1 paź 2024 · This paper discusses solutions for the design and development methods of new compatible restoration mortars for the architectural heritage, covering four significant aspects, namely: i) visual analysis of the heritage building in question, ii) experimental analysis of the original mortar samples for their physical, mineralogical and chemical ...
1 wrz 2007 · This article describes an experimental methodology offering mixing efficiency criteria for granular materials in terms of their dispersion capability. This methodology is based on the analysis of the dispersion kinetics of colored, cohesive, tracer particles that progressively disagglomerate during stirring.
