For ground improvement projects in Taiwan, the jumbo-jet special grouting method is often adopted in consideration of the maturity of construction technology and the project economy. The type of cementitious materials used in this method and the presence or absence of bentonite affects its strength although this is often ignored in the engineering circle in Taiwan. This study aims to address this issue by conducting a series of laboratory experiments under simulated site conditions. The findings are expected to have a positive impact on Taiwan's engineering circle.
