Abstract
This study narrates the quality of concrete production as slump wet in warm and hot zones. The quality of concrete mixture is of inevitable concern to all stakeholders in the construction industry in the zones when the climatic conditions of the zones are considered. Absence of National standards, environmental and climatic conditions and other factors are the main factors that affect the quality of concrete produced in the area. The affected mix ratio is examined and all the prevailing construction/production practices are considered. All necessary measures for improving the quality of concrete produced are surveyed considering the relationships between various variables used in the mixture. Three major factors (variables) that are found to be influencing the quality of concrete in the south east, Nigeria. The absence or lack of implementing the existing building code, climatic conditions in the zones and types of construction materials available, all remain the major variable influencing the quality of present concrete production in the zones of south east, Nigeria.
