Abstract: This paper investigates the temperature–time evolution of the rheological properties of nanosilica (NS)-modified cement paste. A rheometer was used to determine the rheology curves of the paste at 20°C–40°C within 2 h ...

Abstract: Opening holes in construction structures is used often to allocate electrical or ventilating lines. However, it may result in stress concentration and hence the reduction in mechanical properties. In order to manage these ...
