Figure 1 shows the percentage distribution of the data according to the geographical regions of the country for each one of the four strength classes of concrete studied in this work. A first attempt towards reliability-based calibration of Brazilian structural design codes. As the objective of this study was to obtain statistical descriptions that represent the sets of concrete produced in the country, the data from different construction sites were grouped and analyzed in blocks.

The results expressed in the graphics have a strong relation with the strength classes usually used in each region. It should be mentioned that in the existence of an efficient control, the strength values are grouped close to the mean and the distribution curve is high and narrow; on the opposite scenario, the strength values spread out and the curve becomes low and wide. Therefore, this study of strength conformance of the concrete produced in the country is fundamental to achieve the final goal.

Compressive strength of concrete The compressive strength of concrete is random by nature, its variability is a result from the constituent materials, test procedures, production and operation equipments. DON sushi looked spacious and well laid betlneira inside. Acknowledgments The authors are grateful to CNPq for the founding, as well as the professionals betooneira provided the necessary data for the accomplishment of this work: In relation to the regionalized results, concretes produced in the South and Center-West netoneira presented the lower variability than the ones produced in the Southeast and Northeast region.

This figure let clear that in the interval of five years the concrete produced in Brazil presented an increase of mean strength, although the variability also increased.

The variation coefficient was calculated through the ration between the standard deviation and the mean, see Eq. The calibration is being developed by the authors of this paper, though it has already been addressed in a preliminary way by Beck and Doria [ 5 ], Beck et al. Currently only sold on Lazada. September 23, ; Accepted: Table 1 shows a quantification of the specimens according to the different regions. CTS M Sdn Bhd is an established company that is synonymous with power transmission and conveying system related parts and This study was accomplished using a database of over twenty-seven thousand cylindrical specimens molded in loco and tested at 28 days with instantaneous and monotonic load.

Exhibitors, List of Companies at International Foodtec Conveyors Conveying Systems in Some studies also indicate the dosing plants are centralizing the dosage strength in the characteristic strength and not in the average strength [ ]; which is probably the main reason for the frequent occurrences of nonconforming concrete in Brazilian construction sites. These results emphasize the importance of a rigorous control in manufacturing and reception of concretes in order to reduce the nonconforming cases.

It should be mentioned the results from each studied classes came from the same population, which they propose to represent. Figure 7 presents the probability distribution curves based on database from this studyas well as the probability distribution curves based on database from Santiago and Beck [ 1 ] The concrete production involves its dosage which is the process used to obtain the best proportion between cement, aggregates, water, additives and addition in order to meet certain specifications [ 10 ].

Design Optimization for Modification of Trough Belt The necessary measures to reduce variability involves the quality control of each one of the variables and the more efficient it is, the more homogeneous is the concrete produced [ 9 ]. Regional results Figure 5 presents the probability distribution curves obtained for concretes produced in different geographic regions of the country.
