Design and construction of concrete mix proportions under long-distance sea transportation conditions in tropical regions
For the Coal Terminal to serve Java No.7 Power Plant in Java of ua Indonesia,the concrete for the cross beam is designed with strength grade of C40.The concrete is transported by ship to the site and then placed in a hanging tank.It is necessary to ensure that the concrete satisfy the pouring requirements after 3 hours in a non-stirring state,The high temperature in the region throughout the year results in rapid loss of concrete slump,which is even more unfavorable for concrete control.In this paper,by controlling the quality of raw materials,adding mineral admixtures and polycarboxylate high-performance water-reducing admixtures into concrete and other methods,to optimize the mix ratio,improve the mechanical properties of concrete,improve the workability of concrete,and ensure the smooth operation of the project The Implementation of the series of measures can save the costs for the project and provide reference experience for concrete mix design in tropical regions.
