摘要：The invention relates to a product for the internal coating of a pipeline component (1), in particular a metal pipeline component, comprising an internal wall (4) of high curvature. This product comprises a solid charge and a liquid. The liquid is a solution of an alkali metal silicate and the solid charge comprises sand, between 20 and 30% by mass of a binder which sets chemically by reaction with the liquid, and between 4 and 10% by mass of plasticizing adjuvants. The solid charge and the liquid are intended to be mixed (in 5) with a liquid/binder ratio by mass of between approximately 0.3 and 0.45. Application to pipelines for discharge of waste water made of spheroidal graphite cast iron.
