The construction materials used in building
design have changed over time, and their properties continue to evolve.
Currently, the most widely used construction material is concrete. Concrete
possesses important characteristics such as high strength, durability, low
cost, and easy accessibility. However, the preparation and consumption of
cement, which is the primary basic material for concrete, contribute to CO2
emissions, accounting for 5-8% of total emissions. In recent years, researchers
have been conducting various studies to reduce this ratio. One of the most
important alternatives is the use of binders with pozzolanic properties
alongside cement. In this study, mortar specimens were produced using different
proportions of obsidian powder with pozzolanic properties, ranging from 0% to
30%, in conjunction with cement. The compressive strengths of mortar specimens
were measured by subjecting them to mechanical tests on different days such as
3, 7, 14, 28, 56, and 90. However, one of the significant challenges concerns
the direction and rate of change in compressive strengths of concrete at later
ages. To overcome this challenge, the SVM-ARIMA fusion forecasting model is
used in this paper for predicting short-term compressive strengths of mortar
specimens. Using this model, compressive strength values for the next 30 days
were predicted based on the 90-day compressive strength data. The analysis
results yielded R2 values of 0.982, 0.974, 0.979, and 0.977, respectively.
These results indicate that the use of statistical models is appropriate for
predicting the compressive strengths of mortar specimens.
