BACKGROUND AND PURPOSE Information about age-related changes in the striatum comes almost exclusively from cross-sectional studies. We examined age-related differences and longitudinal changes in the volume of the striatal nuclei, compared longitudinal measures of changes with their cross-sectional estimates, and addressed the question of differential aging of the basal ganglia. METHODS We me...

Preventing plastic shrinkage cracks improves the durability of concrete. This is because serve as pathways by which corroding agents can penetrate Freshly cast concrete a saturated mixture reactive and non-reactive materials. As water moves out mass used in hydration process, free reduces. Eventually, be considered to unsaturated. In this research project, viability using soil content sensors m...

Cement quick repair materials generally have the defects of brittleness and early shrinkage. The modification composite cement mortar by water-soluble glue powder—polyvinyl alcohol (PVA)—was studied in condition settled water ratio. At 90 days, maximum flexural strength was 15.4 MPa, which 1.3 times group without PVA there no shrinkage phenomenon. Through analysis porosity, improved total poros...

This paper investigates material properties of metakaolin/slag-based geopolymer mortar (GPM), relevant for composite action with conventional Portland cement-based concrete (PCC). GPM formulations different workability (soft and stiff-plastic consistencies) were developed characterized regard to their compressive tensile strength development over time, shrinkage behaviour during hardening under...

Addition of sulphoaluminate expansive agent could be one useful method to reduce the shrinkage crack destruction shotcrete. While setting and hardening behavior early age mechanical strength cement pastes containing liquid accelerators may influenced by introduction (SEA). Therefore, in this work, hydration different accelerated with SEA was investigated via times measurement, test, isothermal ...
