Annotation. High water absorption in concrete significantly impacts its structural integrity. This article investigated the impact of used engine oil on concrete to assess water absorption, which enhances its durability while also serving as a method for disposing of waste oils, thus reducing environmental risks. Used engine oil was added to the concrete mix at 0.1 % to 1.6 % by weight of cement. The results showed that used engine oil enhanced concrete properties and reduced water absorption by 51 % while maintaining strength without any significant negative effects, also addressed waste management issues in line with environmental sustainability goals.
Keywords: water absorption, concrete, used engine oil, ASTM С1585, durability

Влияние отработанного моторного масла на водопоглощение бетона
Аннотация. Высокое водопоглощение бетона существенно влияет на целостность конструкции. В данной статье исследовалось влияние отработанного моторного масла на бетон для оценки водопоглощения, которое повышает его долговечность, а также служит способом утилизации отработанных масел, снижая тем самым экологические риски. Отработанное моторное масло добавлялось в бетонную смесь в количестве 0,1–1,6 % от массы цемента. Результаты показали, что использование моторного масла улучшило свойства бетона и снизило водопоглощение на 51 %, сохранив при этом прочность без существенных негативных последствий, а также позволило решить проблемы управления отходами в соответствии с целями экологической устойчивости.
Ключевые слова: водопоглощение, бетон, отработанное моторное масло, ASTM С1585, долговечность
