An extensive program of laboratory testing will be undertaken to quantify the extent of cracking in concrete walls and slabs due to early-age cooling and shrinkage of concrete. Analytical models for quantifying restraint in walls and slabs will be developed, as will methods for the prediction and control of crack widths and crack spacings.

将进行一项广泛的实验室测试计划，以量化混凝土墙和板由于混凝土早期冷却和收缩而产生的裂缝程度。 将开发用于量化墙和板中约束的分析模型，以及用于预测和控制裂缝宽度和裂缝间距的方法。
