Salih F. Ensuring the safety of properties of self-compacting concrete mixtures in dry hot climate

Object of research - self-compacting concrete, modified by additives in stages. Purpose of work - increasing the safety of the technological properties of self-compacting concrete in the dry hot climate by repeated addition of additives. Methods. Standard and special tests, rotational viscometery, calorimetry and scanning electron microscopy. Multifactorial modeling and optimization of the modifiers' impact based on temperature and other factors. Theoretical and practical results are in validation of the method of repeated addition of additives to improve the constructions' production technology in a dry hot climate. Novelty of this work is to identify the features of the composition and properties of self-compacting concrete and quantitative assessment of the impact of modifiers. The recommendations to ensure the safety of properties of self-compacting concrete, which are used in Iraq, have been implemented.
