Learn MoreOur products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
concrete elements are designed on the basis of a 28-day cubes crushing strength. a 28-day cubes strength actually represents the characteristic strength of the concrete. it is mandatory to test the concrete cubes or cylinders at the age of 28 days as per almost all building code requirements. now, once your 7-day test and even your 14-day
