| Abstract: | To expatiate how to control the mass concrete crack caused by hydration heat temperature difference when pumping concrete and concrete shrinkage.And pointing out that adding fiber into cement could improve the tensile strength of concrete,control the formation and development of micro fissure in basal body.Combining the calculation of the concrete anti-cracking safety in a certain project,it puts forward that it is feasible and effective to add Dura fiber to prevent mass concrete crack of tall buildings. |
