Studies in Ontario,Canada,indicate that bearing strength is reduced below that expected for granular base (using naturalQ&A: Basics of recycled concrete Fruitful,The demand of recycled concrete and aggregate overall is on the rise. Why is it so, how recycled concrete is used and much more answered in this Q&A. Better loadbearing capabilities have been measured with thinner layer thickness when crushed concrete was used. One other good example is the use of crushed concrete as riprap

Better loadbearing capabilities have been measured with thinner layer thickness when crushed concrete was used. One other good example is the use of crushed concrete as riprap erosion control. What are the benefits of using recycled concrete instead of natural rock? Using recycled concrete saves both the environment and money.Processes Free FullText Study on Mechanical Properties ,Settlement of the pile ends in endbearing rigid pile composite foundations is generally minimal, so only relying on the cushion to coordinate the pile soil deformation may result in insufficient deformation adjustment capacity. Using a deformation adjustor with a specific stiffness on the top of the pile is a method to coordinate pile–soil ,
