Mass concrete wall construction.

Built in a day while t mass walls cost more than wood they also go up faster. When they do there are many options available for insulating concrete masonry construction. This comes with the requirement that any mix considered mass concrete expected to have a core temperature greater than 165 f must have 35 to 50 fly ash or 50 to 70 slag. Although the thermal mass and inherent r value u factor of concrete masonry may be enough to meet energy code requirements particularly in warmer climates concrete masonry walls often require additional insulation.

The insulation must be at least 50 on the exterior or integral to the wall to count. In heavy civil construction the florida department of transportation fdot sets the maximum temperature of concrete at 180 f. The heat takes several hours to travel through the wall before it is released into the home s living areas. Otherwise you re back in the wood frame wall insulation requirements.

Concrete thermal mass walls are not only highly energy efficient and conducive to healthy indoor air but homes built with thermal mass walls require substantially less lumber and produce less construction waste than stick built homes. Any volume of concrete in which a combination of dimensions of the member being cast the boundary conditions the characteristics of the concrete mixture and the ambient conditions can lead to undesirable thermal stresses cracking deleterious chemical reactions or reduction in the long term strength as a result of elevated concrete temperature due to heat from hydration aci 207 1r. A trombe wall is a north facing heavy wall made of concrete or some other thermal mass material located behind a layer of glass. They have acoustic and thermal properties.

It defines mass walls as walls that are made of concrete block concrete insulated concrete form masonry cavity brick earth adobe and solid timber or logs.
