Cement mortar is used as a conglomerate in the majority of construction work. There are multiple variants of cement according to the type of aggregate used in its fabrication. One of the major problems that occurs while working with this type of material is the excessive loss of moisture during cement hydration (setting and hardening), known as shrinkage, which provokes a great number of construction pathologies that are difficult to repair. In this way, the design of a new sensor able to measure the moisture loss of mortars at different age levels is useful to establish long-term predictions concerning mortar mass volume loss. The purpose of this research is the design and fabrication of a new capacitive sensor able to measure the moisture of mortars and to relate it with the shrinkage.
水泥砂浆在大多数建筑工程中用作集料。根据制造过程中使用的集料类型，水泥有多种变体。在使用这类材料时出现的一个主要问题是水泥水化（凝结和硬化）过程中水分过度流失，即收缩，这会引发大量难以修复的建筑病害。因此，设计一种能够测量不同龄期砂浆水分损失的新型传感器，有助于对砂浆质量体积损失进行长期预测。本研究的目的是设计并制造一种新型电容式传感器，该传感器能够测量砂浆的水分，并将其与收缩率联系起来。
