摘要: Abstract Assessment of the optimal mixture is an important issue to obtain desired quality. This paper integrates grey relational analysis and objective weighting technique into Taguchi method propose weighted Grey-Taguchi method. can be employed assess with multiple responses. In application this method, water/cement ratio, volume ratio recycled coarse aggregate, replacement by river sand, content crushed brick, cleanliness aggregate are selected as control factors responses slump, slump-flow, resistivity (7-day, 14-day, 28-day), ultrasonic pulse velocity compressive strength 28-day) concrete. Results demonstrate verify that has a 0.5, fraction 42.0%, 100% 0% water-washed aggregates.
