BRICKS

Exercise 23. Read the text and label the pictures.
Bricks are made from clay. Clay is dried, preheated and fired at 800–1100°C for about three hours. Some types of high-fired bricks are fired at 1100–1200°C. Brick fired at sufficiently high temperatures so that it sinters completely (fireproof brick) is used mostly in chimneys and fireplaces. Brick with a varying degree of high-firing characteristics is available. And it is best to use brick which has been fired at as low a temperature as possible. There are solid bricks and hollow bricks. Additives such as sand, sawdust or finely ground brick can be added to minimize shrinkage during firing. When sawdust is added, it burns off and leaves spaces that have an insulating effect. Brick is, in principle, maintenance-free. A new product is honeycomb brick. Walls made with this are no thicker than 2–3mm. It is made of especially fine-pored clay using thin cellulose fibres as porosity builders. With honeycomb brick, insulation values similar to lightweight concrete can be achieved. Brick can be used as construction material, lining, and floor and ground covering (pavers). There are also special hollow brick block units that can be used in ceilings or walls as well as in floor structures. Brick surfaces can be treated with linseed oil (floors), can be polished, whitewashed or painted (walls). Bricks can be reused after the mortar has been removed. If brick is to be reused, quality control checks for compressive strength, frost resistance and contamination should be carried out. 1.______________ 2._____________ 3._____________ 4.______________ 5.__________ _________
