19	Objective of the Course:	The aim of this course is to introduce the rheological properties of building materials to civil engineers. The effect of the choice of components of cementitious systems on rheological behavior will be examined. In addition, within the scope of this course, students will be given the ability to solve the placement problems that may be encountered in the construction site related to fresh concrete. It is aimed that students will perform small-scale laboratory experiments with the help of a rheometer developed for cement-based materials and gain experience by preparing reports with their findings.
