Optimizing grain size distribution of aggregates
About 70% of concrete volume is made up of aggreggates of various sizes from less than 1 mm up to 64mm or even more although in normal construction a maximum size of 20-32mm is used. One of the most important consideration when combining different sizes of aggregates is the distribution on how much of each [...]
