混凝土地板或楼板的质量在很大程度上取决于达到坚硬耐用的表面，该表面平整、相对无裂缝，并且具有适当的坡度和标高。表面特性由混合比、混凝土浇筑和接缝作业的质量决定。混凝土浇筑作业的时间安排——尤其是修整、接合和养护——至关重要。未能解决这一问题可能会导致磨损表面出现不良特征，例如开裂、耐磨性低、起尘、结垢、高点或低点、排水不良，并增加卷曲的可能性。无论坍落度如何，采用波特兰水泥的混凝土楼板在浇筑后，体积将开始减少。 只要有水、热或两者同时释放到周围环境中，这种现象就会持续下去。此外，由于板坯顶部和底部的干燥和冷却速率永远不会相同，收缩率将在整个深度上发生变化，导致铸态形状变形，体积减小。本指南包含控制混凝土正常体积变化引起的随机裂缝和边缘卷曲的建议。应用现有技术只能减少裂纹和卷曲，而不能消除。即使有最好的地板设计和适当的结构，期望没有裂缝和卷曲的地板也是不现实的。因此，设计师和承包商应告知每位业主，每个项目都会出现一定程度的开裂和卷曲是正常的，这种情况不一定会对地板设计的充分性或其施工质量产生负面影响（Ytterberg 1987； 坎贝尔等人，1976年）。有关地面混凝土板收缩和卷曲的详细讨论，请参阅最新版ACI 360R。有关钢筋混凝土板和非钢筋混凝土板裂缝的详细讨论，请参阅最新版ACI 224R。本指南介绍了如何在各种服务等级的圆形和悬挂式地板上生产高质量混凝土板。它强调施工的各个方面，如场地准备、混凝土材料、混凝土混合比、混凝土施工工艺、接缝施工、接缝间的荷载传递、拆模程序、修整方法和养护。概述了平面度/水平度要求和测量。全面的施工前会议对于促进关键参与者之间的沟通，明确制定施工期间将采用的预期和程序，以达到项目规范要求的地板质量至关重要。 对作业操作，尤其是精加工操作，需要进行充分的监督和检查。

The quality of a concrete floor or slab is highly dependent on achieving a hard and durable surface that is flat, relatively free of cracks, and at the proper grade and elevation. Properties of the surface are determined by the mixture proportions and the quality of the concreting and jointing operations. The timing of concreting operations--especially finishing, jointing, and curing--is critical. Failure to address this issue can contribute to undesirable characteristics in the wearing surface such as cracking, low resistance to wear, dusting, scaling, high or low spots, poor drainage, and increasing the potential for curling.Concrete floor slabs employing portland cement, regardless of slump, will start to experience a reduction in volume as soon as they are placed. This phenomenon will continue as long as any water, heat, or both, is being released to the surroundings. Moreover, because the drying and cooling rates at the top and bottom of the slab will never be the same, the shrinkage will vary throughout the depth, causing the as-cast shape to be distorted and reduced in volume.This guide contains recommendations for controlling random cracking and edge curling caused by the concrete's normal volume change. Application of present technology permits only a reduction in cracking and curling, not elimination. Even with the best floor designs and proper construction, it is unrealistic to expect crack-free and curl-free floors. Consequently, every owner should be advised by both the designer and contractor that it is normal to expect some amount of cracking and curling on every project, and that such occurrence does not necessarily reflect adversely on either the adequacy of the floor's design or the quality of its construction (Ytterberg 1987; Campbell et al. 1976).Refer to the latest edition of ACI 360R for a detailed discussion of shrinkage and curling in slabs-on-ground. Refer to the latest edition of ACI 224R for a detailed discussion of cracking in reinforced and nonreinforced concrete slabs.This guide describes how to produce high-quality concrete slabs-onground and suspended floors for various classes of service. It emphasizes aspects of construction such as site preparation, concreting materials, concrete mixture proportions, concreting workmanship, joint construction, load transfer across joints, form stripping procedures, finishing methods, and curing. Flatness/levelness requirements and measurements are outlined. A thorough preconstruction meeting is critical to facilitate communication among key participants and to clearly establish expectations and procedures that will be employed during construction to achieve the floor qualities required by the project specifications. Adequate supervision and inspection are required for job operations, particularly those of finishing.
