摘要:
This invention relates to compositions comprising a potassium silicate and/or sodium silicate powder having a water content of substantially 0%w/w and an isocyanate,to processes for preparing and hardening these compositions, to a rock bolt filled with the composition and to a rock bolting capsule formed by a water impermeable membrane and containing the composition.
摘要:
The invention relates to organo-mineral systems, obtained by reaction of a polyisocyanate component with a water glass component, whereby the water glass component comprises silane compounds containing at least two primary and/or secondary amino groups. The organo-mineral system can be used for filling drilled holes, cementing anchors in place, as a spray coating for building surfaces and a repair cement for making good defects.
