1. Mesh reinforcement in masonry mortar coatings: a systematic literature review
Abstract Mortar coatings have a major influence on a building’s aesthetics, valorization, and habitability, with significant effects on the mechanical behavior of masonry walls. Multiple types of meshes can be embedded in plaster to enhance both masonry and coating’s mechanical behavior, restrain crack formation, enhance the bonding between layers, and i

2. Methodology for evaluation of the influence of roughness and capillary absorption of ceramic blocks on the render’s tensile bond strength
Abstract The literature indicates that it is difficult or even impossible to associate with strong statistical confidence the bond strength of a mortar coating with the properties of the ceramic block, such as roughness and water absorption. In this work, it is assumed that the variability in capillary water absorption and roughness, and the use of methods t

3. Mechanical properties and fractography of cement-based composites reinforced by natural piassava and jute fibers
Abstract Today’s demand for environmentally friendly and energy-efficient solutions to the construction industry has driven researchers to match natural resources with traditional technics to develop new building technologies. However, there are literature limitations about the correlation of fiber-matrix interface with the failure of natural fibers in mor

4. Evaluation of the use of blast furnace slag as an additive in mortars
Abstract Clinker is the raw material used in the manufacture of cement. However, this material is very harmful to the environment, since it is estimated that for every ton of clinker produced, about 1.0 ton of CO2 is released into the atmosphere. For this reason, alternatives were sought for the use of other materials that are less harmful to the environment

5. Effects of the addition of graphene on the compressive strength of geopolymeric mortar developed from k-feldspar mining waste
Abstract Contemporary organizations are showing a growing interest in the reuse of solid waste from industrial processes with the intention of reducing environmental impacts and reducing costs. The mining activity is one of the main waste generators in Brazil. In parallel, geopolymeric materials have been gaining prominence in studies that make it a possible

6. Prevalence and level of Salmonella spp. Contamination on selected pathways of preparation and cooking of fried chicken at the household level
Abstract Homemade foods have been reported as an important contributor to some foodborne outbreaks. This study determined the prevalence and number of Salmonella spp. on selected pathways of fried chicken preparation and cooking at the household level and investigated their antimicrobial resistance. Salmonella serovar was confirmed by polymerase chain reacti

7. Ternary system Portland cement-calcium aluminate cement-calcium sulfate applied to self-leveling mortar: a literature review
Abstract The modernization of building systems is increasingly demanding products that improve efficiency during their processing. The development of self-leveling mortars for the regularization of flooring is a consequence of this evolution. The high contents of binder and water to obtain self-flowing property, plus the application of thin layers over large

8. Evaluation of mortars produced with Baosteel slag short flow (BSSF) steel slag as fine aggregate
Abstract The objective was to evaluate the influence of Baosteel slag short flow (BSSF) steel slag, a byproduct of a Brazilian steel mill, as a fine aggregate on the properties of fresh state and on the compressive strength of mortars. The experimental work was to characterize the BSSF steel slag and to produce simple mortars (only cement) and mixed mortars

9. CONTRIBUTION OF ENZYMATIC METHOD FOR ANALYZING SUCROSE AND STARCH IN TRADITIONAL CHINESE LIME- AND EARTH-BASED MORTARS
Brown sugar and sticky rice were frequently used as organic additives in Chinese mortars. This study applied enzymatic spectrophotometric methods to identify sucrose and starch contents in traditional Chinese lime- and earth-based mortars. The focus was to understand and evaluate the qualitative detection capacity of enzymatic method in mortars, by first app

12. Hardening and Dynamic Recovery During Hot Compression Test of Copper Simulated as Viscoplastic Material
The Norton-Bailey equation was used to simulate by finite elements the hardening and dynamic recovery of copper during the hot compression tests. The constants of Norton-Bailey equation were determined from the Voce-Kocks model. The simulation assumes a Mortar Contact with Coulomb friction and axial symmetry. Numerical results were compared with experiments.
