To keep the barite in suspension, a minimum gel strength of 3 lbf/100ft2 is required and normally obtained with water-bentonite fluid. The bentonite itself adds viscosity and density to the water. The most common weight treatment is that of increasing the density of the fluid by adding barite.

In this study, barite is used as fine aggregate mixed with Portland cement to design HWC. Different barite concrete mixes were designed, where barite is used once as an addition while maintaining constant the amount of cement (400 kg/m 3) and as a substituent, with different percentage (38, 46, 53 and 57%) to reach different concrete densities.
