  1. 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.

  2. 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).

  3. performed. This Lab manual mainly deals with the common and universal laboratory tests of different types of construction materials. Normal consistency and initial setting time determination of cement; compressive strength of cement mortar; sieve analysis of fine and

  4. 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.

  5. Mortar testing was required to confirm the binder type, mix composition and details of aggregate composition from samples supplied to the laboratory, to enable the mortar in the rebuilt sections to match the existing mortar of the surrounding areas.

  6. 21 sie 2024 · This work presents an analysis procedure to identify mortar binders by combining EDS microanalysis and petrography. Mortar samples of known composition were used as a reference for analyzing mortars from historic buildings.

  7. analysis of historic mortars includes the following: • the composition of the mortar, including the original binder components; the mineralogy, character, and source of the aggregate; and the presence and type of admixtures • the proportions of the original mix, specifically binder-to-aggregate ratio, but possibly also the origi-nal water ...
