Laboratory evaluation of asphalt-portland cement concrete composite
Asphalt-Portland Cement Concrete Composite (APCCC) is a hot-mix asphalt with air voids in the range of 25 to 30 percent which is later filled with resin modified cement grout. The resin modified cement grout consists of portland cement, fly ash, sand, water, and prosalvia (PL7) additive. The …

Geometry assessment and strength/stiffness monitoring of lime and cement modified soils via characterization of curing-induced property changes estimated from seismic wave propagation techniques and electrical resistivity
… via binding additives such as lime and cement grout is a commonly used practice for improving the engineering properties of soil in civil and underground construction applications. Such additives change the properties of the soil by forming cementing agents that bond soil grains …

Iniciação e propagação de fraturas induzidas por injeções em solos argilosos com canalículos: aplicação ao tratamento do solo residual de fundação da barragem de terra da UHE Balbina
… was decided to treat the foundation with a soil-cement grout courtain which, by means of induced hydraulic fracturing, would permit the grout to penetrate and obstruct the intercepted canalicules, reducing the average permeability to values prescribed in the project (K ≤ 10-4 cm/s). This work …

Kinetics of microfine cement filtration during constant rate permeation through sands
Permeation grouting is a cost-effective ground improvement technique that involves the injection of grout into the voids of geological material to improve the engineering properties by reducing the permeability and/or increasing the strength. Permeation grouting can be performed with either …

CHARACTERIZATION OF SENSING REPAIR MATERIALS
… sensing capabilities. In this study, polymer and cement based structural grouting materials with compressive strengths in the range of 30 to 70 MPa were modified to have sensing capabilities. Piezoresistivity was considered as the sensing property and materials were tested under various service …
