砼裂缝产生因素的试验分析

Experimental Study of Portable Infrared Temperature Detector and Concrete Cracks

砼浇筑体在凝固过程中,由于某些原因的影响会出现裂缝。在研究因温度变化引起的板状砼浇筑体裂缝时,需要通过试验来论证,然而因测温仪器和测温手段的限制,使试验搁浅。巧在“非典”期间研发出了“便携式红外体温快速检测仪”,将其用于试验测温,使试验得以继续进行,从而论证了板状砼浇筑体在凝固过程中较大的环境温度温差会使其产生裂缝的现象。

The experiments to research into the relation between ambient temperature difference and cracksof slaty concrete are often unable to carry out,because of the limitation of temperature detectors. Fortunately,we solve the problem by using portable infrared temperature detector invented in the battle against SARS.Based on the experiments,this paper draws the conclusion: great ambient temperature difference is one of thereasons leading to the cracks of slaty concrete in the course of concretion.
