چکیده
مطالعه و تحقیق روزافزون در مورد مواد تشکیل دهنده سازه‌های بتنی، باعث دستیابی به مصالحی شده، که استفاده از آن‌ها به نوبه خود توانسته است، اثرات شگرفی در تولید بتن بگذارد. بتن بدون تردید مهم‌ترین مصالح ساختمانی است، که تولید و مصرف آن روز به روز افزایش می‌یابد و تقریباً در همه سازه‌ها از آن استفاده می‌شود. عملکرد سیمان به عنوان یکی از اجزای اصلی فرآورده بتن همواره مورد توجه بوده است و با توسعه روز افزون صنعت سیمان ایران از نظر کمیت در زمینه تولید انواع سیمان، کنترل کیفیت سیمان با بررسی ویژگی‌های فیزیکی و شیمیایی بسیار مهم است. در تحقیق انجام گرفته سعی گردید تا عوامل موثر در مقاومت سیمان هیدراته مورد استفاده در بتن سازه‌های شهر شیراز مورد بررسی قرار گیرد و نتایج بررسی حاکی از کاهش مقاومت بتن بر اثر افزایش نسبت آب به سیمان و همچنین C3S و C2S دو ترکیب اصلی مسبب مقاومت سیمان هیدراته شده هستند.

چکیده [English]
Increasing study and research on the components of concrete structures has led to the availability of materials, the use of which in turn has been able to have a tremendous impact on concrete production. Concrete is undoubtedly the most important building material, the production and consumption of which is increasing day by day and it is used in almost all structures. The performance of cement as one of the main components of concrete products has always been considered and with the increasing development of Iran's cement industry in terms of quantity in the production of cement, cement quality control by examining physical and chemical properties is very important. In this study, we tried to investigate the factors affecting the strength of hydrated cement used in concrete structures in Shiraz and the results indicate a decrease in concrete strength due to increasing the ratio of water to cement and also C3S and C2S are the two main compounds causing cement strength are hydrated.
