Advantages of pre-fabricated reinforced concrete construction in Iraq

Abstract

With its building infrastructure almost completely destroyed during the military conflict, modern Iraq is facing an urgent need for a number of measures to increase the quality of installation, construction and reconstruction jobs and to reduce timeframes taking into account local and climatic features. To achieve this, the priority task is to develop methods and theoretical recommendations based on the analysis of existing methods for calculating construction timeframes, ones that would most accurately reflect the influence of such factors as cement class, type and an average daily air temperature. The climatic conditions in Iraq impact negatively on the properties of hardened concrete. Specifically, concrete mixture shrinks more rapidly, which entails a change in its physico-mechanical properties and further corrosion of reinforcement bars at joints in monolithic prefabricated housing construction. This paper aims to determine factors that affect construction timeframes and quality for prefabricated reinforced concrete buildings, and to develop a model on the basis of statistical research to determine the concrete hardening time at joints in prefabricated frame housing construction.
