There are many micro-cracks between the stones and the ossified cement grout.
Finally, the bond strength of FRP bars to epoxy resin and cement grout is also studied.
The effect of polypropylene fibre and polymer latex on dry-shrinkage performance of sanded cement grout is researched.
The mixing is a key link in cement grouting construction, and the different mixing manners have an important effect on grout engineering quality.
The conclusion of( mechanic) property of clay-cement grout has been successfully applied to reinforce the roadbed crossing the Jing-Zhu Expressway through a box culvert which is at Renming East Road, Changsha.
They can be laid dry or with cement grouting.
An engineering countermeasure using the superfine cement grouting to patch up the cracks is advanced.
