The materials used in civil construction are undergoing significant advances to achieve reduced maintenance and increased durability. This study analyzed the self-cleaning potential of Glass fiber Reinforced Concrete (GRC) with the addition of titanium dioxide (TiO2) in contents of 3, 5, and 7% with respect to the mass of cement. We evaluated the self-cleaning GRC plates and the compressive and flexural strength of cylindrical and prismatic specimens. Prepared GRC sample plates were stained with dye solution (rhodamine B and methylene blue) and exposed to the four cardinal solar orientations of a building façade (north, south, east, and west) at different inclination angles (0°, 45°, and 90°) with respect to ground level. Results showed that the samples that presented the greatest performance were plates positioned in a north orientation and inclined at 0° in relation to ground level. The inclusion of TiO2 positively affected the consistency of the mixtures and improved the properties of the GRC in the hardened state. Measured rupture stresses were greater than 100 MPa in compressive strength and 20 MPa in flexure. The results of this study showed that the introduction of TiO2 in concrete with high strengths did have great relevance for the self-cleaning of white concrete.

Clay bricks are one of the most widely used materials in building construction due to their advantages, including local availability, ease of fabrication and cost‐effectiveness. Fire is one of the dangerous hazards that can cause damage the life and property. Lightweight plasters play a vital role in insulating the masonry construction during fire accident. There is only limited data and information available on the fire performance of Clay Brick Masonry (CBM) insulated with lightweight plaster. An extensive investigation was undertaken to evaluate the residual strength properties and physical characteristics of CBM prisms exposed to elevated temperatures. CBM prisms plastered with M‐sand mortar, vermiculite mortar, and perlite mortar were used for the investigation. Protected prisms were exposed to elevated temperatures following the ISO 834 standard fire curve for durations of 30 min (821°C), 60 min (925°C), 90 min (986°C), and 120 min (1029°C). Mechanical properties such as axial load carrying capacity, stress–strain behaviour, elastic modulus, and crack pattern were examined. The mechanical properties of CBM prisms were found to be highly influenced by the type of plastering, intensity, and the duration of heating. The microstructure and image analysis confirmed the effects of temperature exposure on protective plasters. Equations are proposed to determine the residual axial compressive strength and the elastic modulus of CBM. It was found that the specimens plastered with perlite mortar had better fire resistance.

Increasing the thermal resistance of masonry wall systems is one of the effective ways to reduce energy consumption in the operation of masonry buildings. This increase is also demanded by newer, more stringent energy codes. However, the effective thermal resistance ( R-value) of masonry walls is affected by many factors, such as thermal bridging, which occurs in places where highly conductive structural components penetrate insulating materials. Thermal bridging is common when connecting masonry veneers to structural backup walls. Furthermore, quick and precise methods for estimating the R-value are needed for thermal design improvements and code-compliance calculations. This study presents a comprehensive literature review on key factors that influence the overall thermal performance of masonry walls, methods to effectively estimate and measure R-values, and improvements in thermal design. In addition to identifying the main technical and practical challenges and the corresponding progress made on each front, key design considerations, such as code compliance, material properties, insulation types, and location, as well as special ties and shelf angles types, are also discussed. This study summarizes critical information and recommendations that will help improve the thermal design of masonry walls, hence reducing the energy consumption of buildings.
