Highly heat insulating load bearing composite masonry - comprising pref. insulation filled perforated bricks and special mortar

摘要

The load bearing masonry walling, for improvement of heat preservation in buildings, has a high heat insulating capacity. It is constructed as a composite unit, incorporating at least two materials. This involves a masonry unit with enhanced heat insulating capacity, such as perforated bricks of at least 75 kp/cm2 crushing strength, with additional heat insulation inserted into its hollow spaces, effecting a heat conductivity coefficient of 0.18 kcal/mh deg.C. This is combined with a special mortar with similar heat conductivity coefficient. Load bearing and heat insulating functions are efficiently combined.
