“…In most cases, dynamic elastic modulus is measured [47][48][49][50][51], while in others the complex experimental fixture described in ASTM 469-02 for the measurement of E in cylindrical concrete specimens [52] was applied to lime-based mortars [53]. The application of strain gauges is usually limited to the lower surface in the flexural strength test, i.e., in the zone subject to tensile stress [54][55], and however a high standard deviation is reported for E measured according to this procedure with respect to dynamic modulus of elasticity [55]. Some authors seem to have determined the Young's modulus by measuring the displacement of the plates of the testing machine [56], which is probably acceptable for weak materials as NHL.…”

“…The incorporation of basalt fibers (chopped fibers, continuous filaments or milled fibers) into mortars (prepared using natural hydraulic lime, dry premix and inert aggregates, respectively dry premix and inert aggregates with crushed bricks and tiles-cocciopesto) was proposed by Santarelli et al [115]. The authors observed that the fibers addition increased the compressive properties of the mortars, while the chopped fibers imparted post-peak stress of the hydraulic lime mortar.…”

Vernacular buildings are usually constructed using materials at hand, including wood, natural stone and bricks (either clay or mud bricks). All those materials are exposed to a series of environmental factors, affecting their structure and integrity. The literature review was conducted using different databases (Scopus, Web of Science, ScienceDirect, SpringerLink) using as keywords the historical material, "heritage" and the terms regarding the desired effect, within the envisaged time period (2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019). The assessment of the results was performed by manual inspection (reading the entire article) and the selection of the works to be inserted in the current review was made by evaluating the contribution to the field. This review summarizes different aspects related to the restoration and conservation of wooden and masonry elements of traditional buildings, including materials used for biocidal interventions, protection against abiotic factors, cleaning and consolidation agents. Finally, a critical discussion regarding the current limitations and future perspectives concludes the review work, envisaging the role of researchers specialized in materials science in the context of cultural heritage conservation.

“…e test results showed that the modified CRC with 1.0% steel fiber content had relatively high compressive and splitting tensile strengths. Santarelli et al [20] studied the physical and mechanical properties and microstructures of three kinds of hydrated lime mortars with different compositions of basalt fibers. It was found that basalt fibers could delay cracking, improve compressive strength, and reduce the capillary water absorption coefficient of mortar.…”

The strength of crumb rubber mortars can be improved by the addition of basalt fibers. However, limited studies have been conducted on basalt fiber crumb rubber mortars (BF-CRM), and the constitutive model is still very immature. In this paper, uniaxial compressive stress-strain curves are obtained for several groups of BF-CRM specimens with different contents. By comparison with the GZH model, modified GZH parameters that can be used in a BF-CRM constitutive model are obtained. Then, taking the support scheme of the main substation of a mine as the background, FLAC3D is used to simulate the roadway support, BF-CRM replaces the ordinary mortars in the original support, and triaxial compression tests are performed at different confining pressures. In this way, the application of BF-CRM in roadway support is studied and analyzed.
