Keep in mind that there will be a natural variation in the color of the CMUs, even if they come from the same manufacturing batch. stream Concrete masonry walls provide benefits such as structural integrity, fire resistance, thermal insulation and mass, low maintenance, and an aesthetic versatility unmatched byany other single building material. For instance, a 6" CMU is nominally 6" deep while a 10" CMU is nominally 10" deep. Acoustical units are often used in schools, industrial plants, and churches, and similar applications where improved internal acoustics are desired. 0000001906 00000 n Disclaimer: Although care has been taken to ensure the enclosed information is as accurate and complete as possible, NCMA does not assume responsibility for errors or omissions resulting from the use of this TEK. /C YJ*g4oGEEv2+K6i4S>d"~2ai7:|T_klw!

Be sure to work with your CMU manufacturer and paint supplier to select the right paint for your situation. Building residential block basements - Concrete Construction ASTM C90 includes minimum face shell and web thicknesses for the different sizes of concrete masonry units as listed in Table 1. 0000023790 00000 n With these and other benefits, it is no wonder that concrete blocks construction has come to be the common sense method of construction.
