[Construction – Section 132]

Clay bricks are very sensitive to moisture. They offer but in dry and hot climate zones of the southern part of the earth-and that, despite less isolation, key advantages over conventional building materials.

The special thing about them is their heat storage. In these countries it is almost year-round sunny. Therefore heat up the mud-brick during the day. At night, they then stored heat slowly. It is built of mud brick building cool during the day and warm night.

Clay bricks are air-dried in the shade. A direct solar irradiation would lead to cracks, because too rapid evaporation of water would arise. This makes bricks unusable or brittle. Only some special bricks species, which in some countries in a special way is to be produced under blazing sun dried.

USE OF CONCRETE AGGREGATES

In construction, the use of recycled concrete aggregates and crushed mud-brick as aggregates in a unbound subbase material news. The results show that the use of recycled concrete aggregates paper increases the optimum moisture content, and reduces the maximum drying density of the subbase material compared to natural materials. Furthermore, the replacement of paper recycled concrete aggregates crushed by mud-brick further increases the optimum moisture content, and reduces the maximum density dry. This was mainly due to the lower density particles and higher absorption of water crushed clay bricks in comparison to the concrete from recycled aggregates. The unsoaked and soaked CBR values of the subbase material, with the total recycled concrete aggregates are lower than those of natural subbase material. The CBR values continue to decrease as the replacement level of recycled fibers crushed by concrete aggregates mud brick increased. However, the soaked CBR values for most recycled subbases, more than 25%, which is a minimal effort. Moreover, the recorded percentage swells to all subbases are less than 0.12%, which is actually irrelevant.
