Shrinkage Characteristics Of South Island Concrete
Elastic modulus of concrete is a simple way of determining the stiffness of the material. stiffness provides restraint and should therefore limit hardened concrete movements such as drying shrinkage. figure 4 shows that whilst concretes had elastic moduli.Energy, characteristic length, and elastic modulus of concrete produced at different strength levels with 28-day target compressive strengths of. 30, 60, and 90 mpa, respectively. concretes considered in this paper were produced using crushed quartzite, crushed granite, limestone, and marble coarse aggregate. the results get.
