The overall objective of this study is to find an alternative solution for the large volume of sludge produced in the wastewater treatment plants in the Gaza strip.
The generated quantities of sludge are expected to be 55.74 tons of solid per day by the year 2025.
This large quantity of sludge is related to the scarcely of land area and high population density represented the Gaza strip sludge problem.
Many researchers worldwide have been trying to explore new and suitable solutions to solve part of sludge problem.
One track of these solutions is to use sewage sludge in construction field.
The current study presents the usage of dry sewage sludge in the concrete mixtures and in manufacturing interlock brick samples.
According to results findings, no significant strength loss was observed when low organic sludge was used in making concrete cube specimens.
The strength loss was increased to 17 % when 10 % of high organic sludge pellets by cement weight was added to concrete mixture.
The results showed that the dry sludge retarded the strength development and has more adverse effect on compressive strength when it has higher organic content and its particles became finer.
The addition of dry sludge to interlock brick paste produced a reduction in compressive strength by only 12 %.
The presence of sludge in interlock samples decreased its density and increased its absorption coefficient. The NEN 7345 leaching test results indicated that the concrete matrix could be fixed more than 73 % of total organic material in the worst case. Finally the study concluded that the dry sludge can be used in as an additive to concrete mixtures and to interlock brick paste as one of the available disposal options for Gaza Strip sludge.
The study recommended that more researches are needed to evaluate the durability of sludge concrete and the behavior of reinforced sludge concrete.
