چکیده

رابطه سن با مقاومت فشاری بتن با استفاده از تحلیل پروفایل‌ها در یک پروژه احداث ساختمان 6طبقه توسط کارشناسان کنترل کیفیت بتن بررسی‌شده است. در این پژوهش، 10 نمونه بتن در شرایط آزمایشگاهی عمل‌آوری شدند و مقاومت فشاری نمونه‌ها توسط 3 کارشناس مورد بررسی قرار گرفت. در فاز صفر با روش مطالعه ابزار، متأثر نبودن داده‌ها از خطای اندازه‌گیری موردبررسی قرارگرفت. در فاز یک با استفاده از نمودار کنترل استور و بریل، پروفایل‌های خارج از کنترل حذف‌شدند و مدلی برای برآورد مقاومت فشاری بتن برحسب سن نمونه ارائه‌شده است. در فاز دو با استفاده از 10000 داده‌ شبیه‌سازی‌شده توسط نرم‌افزار متلب ، عملکرد مدل با استفاده از نمودار (EWMA) موردبررسی قرارگرفت، نتایج نشان می‌دهد که نمودار EWMA قادر به شناسایی سیگنال‌ خارج از کنترل را می باشد، لذا کارشناسان کنترل کیفیت بتن می‌توانند عوامل تخریب بتن را پیش‌بینی کنند و اقداماتی برای ترمیم بتن بدون صرف هزینه‌های زیاد انجام دهند.

چکیده [English]

Compressive strength is one of the important properties of concrete, which is affected by factors such as humidity, water-cement ratio, cement composition, aggregate dimensions, and age of concrete. All cases except age can be controlled by making changes in the mixing plan, therefore, in this research, the relationship between age and compressive strength of concrete has been investigated using profile analysis in a 6-story building construction project by concrete quality control experts. In this research, 10 concrete samples were processed in laboratory conditions after preparation, and the compressive strength of the samples was checked by 3 experts and each expert checked each sample 3 times. In the zero phase, with the Gage study method, the data is not affected by the measurement error. In phase one, by using the Storr and Braille control chart, out-of-control profiles have been removed, and a model has been presented to estimate the compressive strength of concrete according to the age of the sample. In the second phase, using 10,000 data simulated by MATLAB software, the performance of the model has been examined using the (EWMA) chart, the results show that the EWMA chart is able to identify out-of-control signals by applying changes in the model parameters An out-of-control signal can be a warning for signs such as cracking, cracking, sanding, and discoloration at older ages of concrete. Therefore, managers and concrete quality control experts can predict the factors of concrete destruction and take measures to restore concrete without spending a lot of money.
