It is scheduled to be completed by the start of the 2016 construction season. Properties and mix designation Chapter 3 Mix design Chapter 4
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

Aug 14, 2017· In the 1980s, MnDOT and other state transportation agencies began using such recycled aggregate in the concrete course as well. But this latter practice was discontinued by the early 1990s due to mid-slab cracking observed in pavements constructed with such concrete. Using recycled concrete aggregate (RCA) in the base course has continued, however.
Class 5, Architectural Concrete, Class S Severe Weather Exposure, which covers all of Minnesota, still allows a fraction of the aggregate to contain particles which are not freeze/thaw durable. Similarly, MN/DOT Specification 3137 allows the same. Even with aggregates conforming to ASTM C33 5S and MnDOT 3137, popouts can
Effects of Aggregate Properties on Concrete Size Grading. Effects of aggregate properties on Concrete like Grading of aggregates depends on the proportions of coarse and fine aggregate If grading of aggregate is varied it also changes cement paste content cost economy workability of the mix density and porosity It is an important factor and has a maximum influence on workability

In general, the amount of adhered mortar and the quality of the original concrete have a significant effect on the properties of resulting concrete. The increase of RA content and w/c ratio results in poorer durability of concrete. In comparison, the negative effect of recycled fine aggregate is more obvious than that of recycled coarse aggregate.
