In one kind of construction, blocks of materials such as brick, stone, orconcrete, are put together to form solid walls. These materials are heavy, however, they can support the structural loads because they have theproperty of high compressive strength. Walls made up of blocks bothsupport the building and divide the space in the building. 2. In another type of construction, sheet materials are used to form walls, which act as both space dividers and structural support. Timber, concreteand some plastics can be made into large rigid sheets and fixed together to Unit 1: Properties and shapes Page 9 of 9form a building. These building are lighter and faster to construct made up of blocks thanbuildings. 3. Rod materials, on the other hand, can be used for structural support, but notfor dividing spaces. Timber, steel and concrete can be formed into rodsand used as columns. Rod materials with high tensile and compressivestrength can be fixed together to form framed structures. The spacesbetween the rods can be filled with light sheet materials, which act asspace dividers but do not support structural loads.Now say which paragraph discusses:a). constructionb Planar). Frame constructionc). Mass construction
