Fundamentals of Concrete

For example, consider a concrete mix design that calls for 282-pounds of water (ie free- water) and contains 1100 pounds of fine aggregate and 2000 pounds of coarse aggregate The mix design shows fine aggregate absorption to be 2% and coarse aggregate...

What is the size of coarse aggregate used in concrete?

Generally the size of coarse aggregate used is 10-125 mm If we use the proportional mix of different sizes small to large (>45 mm to 20/25 mm), this make the concrete structure compact by align themselves in voids depending upon their size and compact mass will be formed with increased strength...
