Abstract :
Background and Objective: Global warming is caused by the emission of greenhouse gases, mainly (CO2). Reducing greenhouse gases and monitoring the environment are important goals of today's mankind. Cement factories are the main producers of greenhouse gases. The main goal of this research is to find a material with cement properties (pozzolan) that can be replaced in a part of concrete cement with the aim of reducing cement consumption and reducing CO2 greenhouse gas emissions. The local mineral pozzolan under research has similar properties to world-famous pozzolans and has the relevant standards.Material and Methodology: To find the optimal amount of pozzolan in the concrete, In Sep. 2021, four cases of 5, 10, 15 and 20% by weight was studied and its effect on concrete compressive strength and CO2 emissions and its ability to reduce pollution Environmental was evaluated in comparison with conventional cement concrete. Findings: Experiments showed that the best amount of replacement of this pozzolan to cement in concrete is 15% by weight and increases the strength by 2.4%. Also, this pozzolan emits less CO2 than normal cement concrete equal to 15.20 kg/m3.Discussion and Conclusion: Considering the favorable effects of this pozzolan in strengthening the structure and reducing the consumption of cement in concrete, it can be introduced as a cement-reducing and environmentally friendly material.
