Using the smeared crack model available in DIANA, and from the effect of decreasing the thickness of the overlay of repair mortar (from 60 to 15 mm), and by decreasing the bond strength between repair mortar and substrate from 3 to 1 MPa, it is shown that the number of hygral shrinkage …
WebThe negative effects of concrete shrinkage lead to inefficient designs and material use, dramatically shortened service life of concrete structures, huge maintenance costs, and CO 2 emissions. PrīmX concrete is made with chemical compressive self-stress for stronger material, stiffer section, and improved hygral shrinkage control.
