Dense aggregate light aggregate and cellular aircrete sometimes known as aerated concrete.

Concrete blockwork can generally be divided into three categories. C w m k is the concrete thermal conductivity and. And the thermal conductivity is 0 12 w m k the same with aerated concrete. 400 x 250 x 200mm l x w x h 3.

Their distinctive properties of durability and strength make them an ideal and cost effect solution for all types of load bearing walls. This paper investigated the thermal properties of hollow shale blocks and walls. C k w is the thermal resistance of the concrete section l m is the thickness of the section in the direction of the heat flux k. Dense aggregate concrete blocks are manufactured from cement sand and aggregates.

It is a readymixed concrete solution offering improved thermal conductivity performance actual range λ 0 45 to 0 54 w m k with assured structural performance 30 n mm2. Thermal conductivity is a material property that describes ability to conduct heat thermal conductivity can be defined as the quantity of heat transmitted through a unit thickness of a material in a direction normal to a surface of unit area due to a unit temperature gradient under steady state conditions.
