چکیده

بتن یکی از مصالح شاخص و پرکاربرد در صنعت راه و ساختمان است. ساخت بتن رنگی نیز در دهۀ اخیر از طرح‌های نوین تحقیقاتی صنعت یادشده است. بتن‌های رنگی در سازه‌های شاخص شهری علاوه بر مقاومت مطلوب نسبت به بتن معمولی و دیگر مصالح در بهبود پالت رنگی شهر و غنای چشمی محیط‌های شهری نقش بسزایی دارد. هدف از پژوهش حاضر، بررسی تأثیر رنگ‌دانه‌های معدنی بر مقاومت فشاری بتن رنگی با تأکید بر نقش بهبود پالت رنگی شهرهای معاصر است. بدین منظور نمونه‌هایی از بتن رنگی با 2، 4 و 6 درصد رنگ‌دانه و بتن معمولی مورد آزمایش قرار گرفت. نتایج پژوهش بیانگر درصد افزایش مقاومت نمونه‌های بتن رنگی نسبت به بتن معمولی به ترتیب 2.3، 4.9 و 8 درصد بوده است که این مهم بر مقاومت و استحکام بتن رنگی برای استفاده در سازه‌های شهری تأکید دارد.

چکیده [English]

In the civil engineering industry, concrete is a material that is widely used and highly significant. The production of colored concrete has also been considered in recent decades as one of the emergent research projects in the desired industry. Using colored concretes in prominent urban structures, besides adding the desired resistance to usual concrete and other materials, play an important role in improving the urban`s color palette and the visual richness of urban environments. This study aims to investigate the effect of mineral pigments on the compressive strength of colored concrete by focusing on the role of the improved color palette in current cities of Iran. For this purpose, the samples of colored concrete with 2, 4, and 6% pigments compared to ordinary concrete were tested. The research results showed that the percentage increase in the strength of colored pigmentation of concrete samples compared to the usual concrete was 2.3%, 4.9%, and 8%, respectively, which emphasizes the strength and rigidity of colored concrete to be used in urban structures.
