Abstract

Grouting is the most common technical method with many applications; e.g., it is used for soil stabilization and strengthening, for reduction of water ingress to underground facilities or of water loss through a dam foundation, etc. Grouts comprise several constituents, that are combined in many ways depending on the in situ conditions and the outcome desired each time. Superplasticizers, accelerators, antifreezers, air-entraining agents and many others are generally used to improve the quality of cement grouts and, consequently, their effectiveness on strength (especially bond strength), durability, impermeability, and resistance to chemical erosion of the grouted soil or rock mass.

A comprehensive laboratory work was carried out in order to study the rheological properties of acrylic resin (latex)—superplasticized grouts and their influence, when injected, on the physical (water permeability, porosity) and mechanical characteristics (compressive strength, elastic modulus, durability) of a granular soil.
