The results confirm the orthotropic nature of masonry where for hollow blockwork, tensile strength parallel to the bed joint is two to four times higher than tensile strength normal to the bed joint. Grouting of the blockwork resulted in a greater increase of strength for tension normal to the bed joint so that these ratios are between 1 and

Lightweight concrete can be defined as a type of the concrete which is lighter than conventional concrete density in the range of 140 to 150ib/ft3 (2240to 2400 kg/mm3). Lightweight concrete can be categories into three types which is nofine concrete, aerated/foamed concrete and lightweight aggregate concrete.
