Abstract
As a result, the lowest plastic viscosity was observed in mixtures with DS/FA ratio of 20% and increased as DS/FA ratio increased over 20%. The yield stress decreased as DS/FA ratio increased up to 20% or 40% and increased over those DS/FA ratios. The detailed DS/FA ratio which could lead to the lowest plastic viscosity and the lowest yield stress was calculated by regression. The DS/FA ratios for the lowest plastic viscosity were 33% in W170 mixtures and 28% in W160 mixtures. Also, the DS/FA ratios for the lowest yield stress were 32% in W170 mixtures and 37% in W160 mixtures, respectively. The effect factor of crushed sand (CS) on the plastic viscosity could be calculated the range of 49-57% in comparison with the effect factor of DS, and the range of the effect factor of coarse aggregate (CA) was 2-56%.
