Abstract

Chemical stabilization by cement is among the factors of optimizing the soil performance. Numerous studies have been performed in the field of using cement as a stabilizing material (Naderi Nia- Naeini SA, 2009; Dupas J, Pecker A, 1979). The results of this research show that the addition of cement to the soil increases stiffness and improves soil’s failure behavior and its engineering properties. Improving the engineering properties of the soils stabilized with cement is essentially due to hardening of cement as a result of hydration of cement and forming additional cementitious materials between the hydrated cement and clay particles in the soil (Shihata SA, Baghdadi ZA, 2001).
On the other hand, although cement industry has adopted the most modern technologies to reduce pollution, different stages of cement production and transportation have a great share in the environmental pollution. Studies indicate that to produce one ton of cement and clinker in Iran 0.655 and 0.79 tons of CO2 greenhouse gas are emitted respectively (Milika Bildrici 2019).
Therefore the cement mix optimization is such that the lowest amount of energy is used to produce it with the least damage to natural resources and finally the best performance possible is provided which is considered as a main goal (Khaleghi, M. H. 1990).
