Unlike more traditional materials, such as wood siding or cement-based stucco, a critical flaw of the new materials is that any water or moisture that penetrates into the system, either through cracks in the surface (caused by thermal expansion or damage), unsealed joints, or incorrect flashings, becomes trapped inside the wall, potentially ...
One reason why the carbon emissions are so high is because cement has to be heated to very high temperatures in order for clinker to form. A major culprit of this is alite (Ca 3 SiO 5), a mineral in concrete that cures within hours of pouring and is therefore responsible for much of its initial strength. However, alite also has to be heated to ...
The leaky homes crisis is an ongoing construction and legal crisis in New Zealand concerning timber-framed homes built from 1988 to 2004 that were not fully weather-tight. . The problems often include the decay of timber framing which, in extreme cases, have made buildings structurally unsou
Stucco plaster reliefs, such as this work at the Château de Fontainebleau, were hugely influential in Northern Mannerism. A plaster low-relief decorative frieze is above it. Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. [ 1 ]
Stucco or render is a construction material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as a decorative coating for walls and ceilings, exterior walls, and as a sculptural and artistic material in architecture.
Because the masonry veneer is non-structural, it must be tied back to the building structure to prevent movement under wind and earthquake loads. Brick ties are used for this purpose, and may take the form of corrugated metal straps nailed or screwed to the structural framing, or as wire extensions to horizontal joint reinforcement in a fully masonry veneer or cavity wall.
In materials science, creep (sometimes called cold flow) is the tendency of a solid material to undergo slow deformation while subject to persistent mechanical stresses. It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material. Creep is more severe in materials that are ...
The ground froze on June 9; on June 12, the Shakers had to replant crops destroyed by the cold. On July 7, it was so cold that all of their crops had stopped growing. Salem, Massachusetts physician Edward Holyoke—a weather observer and amateur astronomer—while in Franconia, New Hampshire, wrote on June 7, "exceedingly cold.
