In order to demonstrate more specific features of each region, the climate was partitioned in subunits.
Thus, consistency correction through water addition or other plasticizer additives are common. Our mission is to drive science-based innovation that achieves breakthrough outcomes for children facing adversity. Concrete slump correction with water, nbr or even a combination of both is a usual and traditional practice to solve material loss [6, 11, 12].

After the preparation 0 min and after 30, 60, 90,and min, concrete samples were taken, in order to verify slump loss, through slump test, as shown in Figure 2. International standards have a methodology for analysis of similar. Tecnologia do concreto estrutural: Considering such environmental factors and admitting that concrete is hardly ever placed immediately after its preparation, water addition to adjust the material consistency is a usual practice at construction sites in the studied region.
