Abstract

Тема выпускной квалификационной работы: «Влияние кристаллообразующих добавок на физико-механические свойства бетона». Работа посвящена исследованию физико-механических свойства бетона с применением кристаллообразующих добавок. Задачи, которые решали в ходе исследования: 1. Анализ научной литературы о влиянии кристаллобразующих добавок на физико-механические свойства бетона. 2. Выбор испытаний для исследования физико-механических свойств бетона. 3. Изготовление образцов для проведения испытаний физико-механических свойств. 4. Проведение испытаний по определению морозостойкости, водонепроницаемости и прочности. 5. Анализ результатов испытаний по определению физико-механических свойств бетона. Экспериментальные исследования проводились на базе учебной лаборатории «Аддитивные технологии и 3D принтинг» Инженерно-строительного института СПБПУ и аккредитованной научно-испытательной лабораторией «ПОЛИТЕХ-СКиМ-ТЕСТ» в соответствии с апробированными методиками с использованием сертифицированного оборудования. В ходе испытаний определялись такие физико-механические характеристики как прочность на сжатие и растяжение при изгибе, морозостойкость и водонепроницаемость бетона. Для испытаний по определению морозостойкости использовался программно-технический комплекс «КОНТАР- Консоль». По результатам экспериментальных исследований сделаны выводы, что кристаллообразующие добавки показывают возрастание и стойкость бетона против коррозионного и морозного разрушения, что свидетельствует о возможности значительного повышения долговечности конструкций.

The subject of the graduate qualification work is "The effect of crystal-forming additives on the physical and mechanical properties of concrete". The work is devoted to the study of the physical and mechanical properties of concrete with the use of crystal-forming additives. The research set the following goals: 1. Analysis of scientific literature on the effect of crystal-forming additives on the physical and mechanical properties of concrete. 2. Selection of tests for the study of physical and mechanical properties of concrete. 3. Production of samples for testing physical and mechanical properties. 4. Conducting tests to determine frost resistance, water resistance and strength. 5. Analysis of test results to determine the physical and mechanical properties of concrete. Experimental studies were conducted on the basis of the educational laboratory "Additive Technologies and 3D Printing" of the SPBPU Institute of Civil Engineering and the accredited scientific testing laboratory "POLYTECH-SKIM-TEST" in accordance with proven methods using certified equipment. During the tests, such physical and mechanical characteristics as compressive and tensile strength during bending, frost resistance and water resistance of concrete were determined. For tests to determine frost resistance, the software and hardware complex "KONTAR - Console" was used. According to the results of experimental studies, it was concluded that crystal-forming additives show an increase and resistance of concrete against corrosion and frost destruction, which indicates the possibility of a significant increase in the durability of structures.
