The 28-Day Myth - National Precast Concrete AssociationOct 28, 2013 . Some regulators characterize concrete as “green” if it has not cured for a certain time frame, not realizing this leads to unnecessary delays and higher project costs. An evaluation of the concepts of measured compressive strength and curing is in order to shed light on the mystery that surrounds the 28-day.concrete strength chart,Strength of ConcreteStrength of Concrete. ▫ In concrete design and quality control, strength is the property generally specified. ▫ This is because, compared to most other properties, testing strength is relatively easy. ▫ Furthermore, other properties of concrete, such as elastic modulus, water tightness or impermeability, and resistance to.Compressive Strength of Concrete -Cube Test, Procedure, ResultsApr 2, 2014 . Compressive strength of concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher.
