INVESTIGATION OF THE EFFECT OF SEWAGE SLUDGE ASH ON THE MECHANICAL PROPERTIES OF MORTAR SPECIMENS

In recent years, the rising awareness of environmental protection and the rapid depletion of natural resources have increased the strategic importance of sustainable building materials, especially in the construction sector. Increasing construction trends lead to a noticeable increase in the use of materials. In this context, the environmental impacts of cement production come to the forefront with the amount of energy used in clinker production and the resulting CO2 emissions. Recycling of waste materials can solve the problem of waste storage and reuse of waste materials can form the basis of sustainable construction approaches to reduce energy consumption. This research focuses on the incineration of dewatered sewage sludge into ash and its usability as a building material. In this context, the incinerated sewage sludge ash was ground and used as an additive material at different ratios instead of cement to produce mortar specimens. Flexural and compressive strength tests were carried out to determine the mechanical properties of the sewage sludge ash admixed specimens by comparing them with mortar specimens produced with Class F fly ash on the 7th, 28th and 90th days.
