The experiments were carried out with the grout mixtures including of 4, 8, 12, 16 and 20% content of RHP and 0.75, 1.00, 1.25 and 1.50 ratios of water–cement. The purpose of the study is to provide a new knowledge about using RHP as a filler in cement grouts in order to improve the grout methods and services, and achieve a good product performance. Test results showed that the increase in RHP content in the mix increases the plastic viscosity with all water–cement ratios. At 0.75, 1.00 and 1.25 ratios of water–cement, the grout mixtures showed shear-thinning behavior. On the other hand, this behavior changes to shear-thickening behavior at w/c = 1.50 at all RHP percentages. Experimental results indicated that this waste product can be utilized as a filler in cement grout for geotechnical application such as filling large voids.

The experimental program consisted of fifteen different mixture having 5%, 10%, 20%, and 30% RHA content and three different water to binder ratios (w/b = 0.75%, 1.00%, and 1.25%). Workability properties (marsh cone flow time, plate cohesion, and mini slump diameter), plastic viscosity, apparent viscosity, and the yield stress of the mixtures were determined. Test results showed that increasing replacement level for the RHA amount increases marsh cone flow time, plate cohesion, plastic and apparent viscosity, and the yield stress, but also decreases mini slump diameter. Shear thickening and pseudo-plastic behavior was observed for high RHA content for w/b ratios greater than 1.00.

The investigates the fluidity and rheological properties of the cement based grout mixed with rice husk powder (RHP). The experimental program consisted of twenty-four different mixture having 4%, 8%, 12%, 16% and 20%. RHP content and four different water to cement ratios (w/c= 0.75, 1.00, 1.25 and 1.50). Workability properties (marsh cone flow time, plate cohesion, and mini slump diameter), plastic viscosity, apparent viscosity, and the yield stress of the mixtures were determined.
