A silicon piezoresistive sensor is applied here to in-situ record the curing stress profile, the distributions of the residual stress and the stress evolution profile during thermal treatment.
On similar projects, with 50m span length (single spans, cantilevering 1/5), the cycle time is usually approx. 10 - 12 days without steam curing, reinforced in-situ by hand.
类似项目50米跨（单线，1/5悬臂）没有使用蒸汽养生和预制钢筋笼，一个工作循环为10-12天。

The vulcanization course of NR with traditional sulfur curing system was tracked insitu by FTIR and the effect of the new anti-reversion agent Z-500 on the vulcanization of NR was investigated.
