Paper Title:
Optimized Aggregate Gradation for Bangladesh
  Abstract

Aggregate is one of the most important and strength determining ingredients of concrete as it serves as reinforcement and occupies three quarter of the total volume of concrete. Moreover, for good compact concrete, aggregate with minimum void is always desirable. This paper represents a study on obtaining the effective dense gradation by combining naturally available aggregate in Bangladesh. In this purpose a program has been developed based on analytical approach to find out the desired mix proportion of different aggregate samples to reach the target of getting an compact, economic and environment friendly concrete. Finally after preparing the concrete in the laboratory with different mix design ratio and combined gradation of prepared single sized aggregate is found to have 20% more strength than that of the concrete made with the same design mix and combination of aggregate gradation presently available in the industry.
