Investigation of effects of Portland cement fineness and alkali content on concrete plastic shrinkage cracking

From a material viewpoint, modern concrete’s frequent propensity to plastic shrinkage cracking can be attributable to a combination of low water-binder ratio use and ever-changing properties of binding materials. To obtain a better understanding of this phenomenon, this paper explores the effects of cement fineness and alkali content on the plastic shrinkage cracking of concrete manufactured with two water-binder ratios. Results indicate that...
