Methods of Processing Efflorescence of Clay Brick

The current work involves an experimental investigation of the efflorescence processing in clay brick. The experimental program consists of forming and testing forty-two specimens. The main variables considered in this study were: the effect of using artesian wells water, the amount of salts in the soil used, use silica fume, use dates vinegar, use kaolin, use waste glass powder and clay brick burning temperature on the phenomenon of efflorescence. The second part of this study is concerned with how to remove the efflorescence after completion of construction or during construction. From the results of this work, it was concluded that the average of efflorescence was reduced by a very large percentage of about 92.02% when the addition of silica fume 15% of soil weight. It was found that the best technique to processing efflorescence was used dates vinegar because this technique was highly decreased an average of efflorescence (about 89.69%), simple and cost-effective. Also, the best efflorescence removal techniques were washing clay brick by using dates vinegar.
