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 the water loss through a dam foundation etc. Grouts comprise several constituents which 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, durability (especially bond strength), impermeability and resistance to chemical erosion of the grouted soil or rock mass.

A comprehensive research work was carried out concerning 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) of sand.

Keywords: stabilization, cement, acrylic resin, superplasticizer, viscosity, compressive strength, slaking, porosity.
