Influence of sludge content on compressive strength of sintering sludge-shale bricks

Sintering sludge-shale brick is a new kind of environmental protection and energy saving material. In order to study the different sludge content on the influence of compressive strength of sintering sludge-shale bricks, through the experiment and comparison to the finished products of the five groups of the sludge content with the method of contrast test, the reasonable content is found. The result shows that the compressive strength of the brick decreases sharply with the increase of the sludge content in the same experimental condition. In order to realize the greatest degree of sludge utilization, the best sludge content of sintering sludge-shale brick is 30%.
