Later, there were construction materials such as earthen bricks, clay bricks, and wood in the mountains. In modern times, concrete with sand and gravel was used. How to get materials on site and even use waste to make durable building materials becomes a challenging direction. In addition, in the country, the removal of sludge from the reservoir is an important issue to extend the life of the reservoir. How to deal with sludge is even more critical. Previous studies have used a new generation of inorganic polymer materials as cement to enhance the performance of alumina bricks, but their strength is still less than that of high-pressure bricks. If the concept of making high-pressure bricks can be combined with the bonding reaction of inorganic polymeric materials, there is a chance to achieve the goal of recycling the muddy reservoir. In this study, the reservoir sludge was added to the inorganic polymerization liquid to mix the slurry, and the test body was prepared by compaction to test the compressive strength and other properties. Although the result is not satisfactory, it also has a strength of about 50 kgf/cm2 or more. If a small amount of solid matter is replaced by hearth powder, its 28-day average compressive strength can reach 243 kgf/cm2, which exceeds the CNS specification of two bricks with a strength of 200 kgf/cm2. In terms of the overall results obtained, different properties can be used for different applications, and it is a beginning for the consumption of reservoir sludge waste.
