Lightweight CMU

WebConcrete containing lightweight aggregates and carbonate aggregates retain most of their compressive strength up to about 1200 oF. Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and therefore generally provides increased fire resistance. WebLightweight CMU is made with lightweight course aggregates whereas normal-weight units are made with normal-weight coarse aggregates. Lightweight CMU is not as strong under compression and loads as … WebUse Lightweight CMU When Available Concrete masonry can be manufactured with different types of lightweight aggregates, providing lighter weight units that reduce the load on a structure. Lightweight CMU also offers higher sound ratings, fire ratings, and greater insulating properties. cytanet news today
