Influence of the Polymer Styrene Butadiene Rubber on Some of Clay Brick Properties

Abstract

This research studied the improvement of clay brick durability by using twomethods of treatment, the first one by coating with Styrene Butadiene Rubber(Polymer) solution and the other by submerging bricks in polymer solution forvarious periods.The results showed that using coating method causes a slight increase in thecompressive strength with a maximum percentage of 3.8% for both yellow andgreen brick in comparison with untreated bricks, while the compressive strengthfor the two types of the brick reduced when they treated using submergingmethod, the percentage of reduction increases by about 26% and 7% for yellowand green brick respectively at submerged period of 24 hours.The results also indicated that no efflorescence appears for all treated bricks(treated by coating and submerging methods for all periods) and a decrease inabsorption with maximum percentages of 26.8% and 14.5% for yellow and greenbricks respectively when the specimens submerged in polymer solution for 24hours. All the results were compared with tested samples untreated with polymersolution.
