چکیده
امروزه بتن به عنوان پرمصرف ترین و رایج ترین مصالح ساختمانی، در توسعه زیرساختهای عمرانی و اقتصادی به کار می رود. بتن از سیمان پرتلند معمولی حاصل می شود و با توجه به میزان مصرف بالای بتن و نیاز روزافزون به تولید سیمان، تحقیقات نشان می دهد که در آینده میزان تقاضای بتن سیمانی افزایش خواهد یافت و از سوی دیگر تولید سیمان مستلزم مصرف منابع طبیعی از قبیل برق و سوخت فسیلی و همچنین رهاسازی حدود 7 درصد از گاز CO2 به محیط است و فرآیند تولید آن بعد از فولاد و آلومینیوم بیشترین مصرف انرژی را دارد، به همین دلیل ارائه محصولات جایگزین جهت حرکت در مسیر توسعه پایدار، اصلی ضروری به شمار می آید. در استراتژی های میان مدت و بلند مدت کاهش گرمایش جهانی ناشی از صنعت سیمان، توسعه تکنولوژی های به صرفه به لحاظ مصرف انرژی و کاهش دهنده انتشار CO2و توسعه آنها در بازار بسیار کلیدی خواهد بود. قابلیت های سیمان ژئوپلیمری در زمینه ذخیره سازی انرژی و کاهش انتشار CO2در مقایسه با سیمان پرتلند بسیار قابل توجه می باشد بگونه ای که این تکنولوژی ضمن اینکه عملکردهای قابل مقایسه ای را با مواد سیمانی تجاری فراهم می آورد می تواند انتشار CO2 ناشی از صنعت سیمان را به اندازه80% کاهش دهد.

چکیده English

Today, concrete is used as the most widely used and common building materials in the development of civil and economic infrastructure.
Concrete is made from ordinary Portland cement, and due to the high consumption of concrete and the growing need for cement production, research shows that in the future the demand for cement concrete will increase, and on the other hand cement production requires the consumption of natural resources such as electricity. And fossil fuels, as well as the release of about 7% of CO2 gas into the environment, and its production process consumes the most energy after steel and aluminum, so the provision of alternative products to move towards sustainable development is essential.


In the medium and long term strategies to reduce global warming due to the cement industry, the development of energy-efficient technologies to reduce CO2 emissions and their development in the market will be very key.


The capabilities of geopolymer cement in the field of energy storage and reduction of CO2 emissions are very significant compared to Portland cement, so that this technology, while providing comparable functions with commercial cementitious materials, can reduce CO2 emissions from the cement industry. Reduce by as much as 80%.
