The Designer and Contractors are mainly responsible to\nminimize this type of cracking by following the specifications limits and doing\nthe temperature control on time.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Usage of Port land Cement that generates\nrelatively low heat.<\/li><li>Avoid specifying&nbsp;\nan excessively low w\/cm (water-cementitious materials ratio)<\/li><li>Thermal Control measures has to be decided\nbefore starting the construction<\/li><li>Using the cooling pipes if necessary during the\ncooling process.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Drying Shrinkage Cracking<\/strong><\/h3>\n\n\n\n<p>Drying Shrinkage mainly occur for usage of more water in\nconcrete mix.
