Giatec iCOR™

Giatec iCOR™是一款测量多种混凝土表面参数的手持式装置。iCOR™运用最先进的算法对所收集的数据进行分析,从而快速准确地得出钢筋的 “锈蚀速度” 。钢筋的“锈蚀速度”是估算混凝土结构使用寿命最重要的参数。该技术曾用于2013年7月的对埃利奥特莱克(Elliot Lake)商场坍塌事件调查的取证分析。

在有一个小的极化(ΔE < 20 mV)和腐蚀电位周围的电流(ΔI)之间存在线性关系,这一假设是几乎所有钢筋混凝土结构腐蚀速率测量技术的基础。其中,Rp=∆E/∆I,其中Rp为所谓的极化电阻。一旦确定极化电阻(Rp)的数值,就可以用斯特恩基尔方程,icorr= B/(AxRp)来算出腐蚀速率;其中A是钢筋极化面积的临界值,B是由于阳极和阴极的塔费尔斜率决定的常数。极化电阻(Rp)的数值可通过直流(DC)或交流(AC)阻抗谱测得。交流(AC)技术需要在非常低的频率进行和较长的测量时间,而腐蚀电位可能无法再测量期间保持稳定。此外,交流阻抗谱需要专业人员的来读取分析。恒电流脉冲和带有传感电流遏制的线性极化技术是目前运用最广泛的现场直流电测试技术。对这项技术内在问题的研究和关键评论都以非常充分,这为研发Giatec iCOR™提供了强大的动力。

What Giatec iCOR™ “不是”:

Giatec iCOR™ 不是一个半电池电势的测量装置,所以它不仅能提供腐蚀的可能性,还能提供腐蚀速率。

Giatec iCOR™ 不使用极化电阻(RP)来测定腐蚀速率,所以它没有使用极化电阻带来的常见问题。

Giatec iCOR™ 不会极化螺纹钢,所以它不需要极化面积来计算腐蚀速率。

Giatec iCOR™ 不需要电流限制保护环,因为它没有极化电流通过混凝土和钢筋。

Giatec iCOR™ 避免了使用费时且复杂的交流阻抗测量方法,且依然能提供对腐蚀速率的精确测量。
