The usability of olive seed and ash in cement-based composites

Cement-based composite materials are examples of composite materials whose binder material is cement, reinforcement material is aggregate. The use of cement-based composites is becoming more and more widespread due to reasons such as the rapid increase in the population, the rapid development of the construction sector and the necessity of change, especially with the increase in natural disasters in recent years. Considering the CO2 emissions released in cement production, the energy spent on aggregate supply and environmental pollution, the search for alternative materials is becoming important Jul. In the study, olive kernel and aggregate were replaced at the rates of 10%, 20%, 30% by weight, olive kernel ash and cement at 1%, 3%, 5% by weight in order to examine the usability of olive kernel and olive kernel ash in different areas in cement-based composites. A total of 9 different mixtures were obtained and the cube and beam were subjected to experiments in different sizes as samples, under different curing conditions as air and water curing. Bending strength, compressive strength, carbonation, water absorption, capillary water absorption, UDH, wear resistance, test hammer and splitting experiments were performed. As a result of the study, it was determined that olive seed ash provides improvement in strength by adding to the mortar, reduces the vacancy rate by acting as a filler, while olive seed additive increases the vacancy rate and reduces the strength as the core rate increases.
