Evaluation on Compressive Strength and Workability of Green High-Performance Concrete by Grey Relational Grade
Applying grey relational analysis method, this paper calculated the relational grades between the mix proportion parameters and the compressive strength, the slump of green high-performance concrete (GHPC) respectively. Besides, the sequence results of influencing degree of the factors affecting the compressive strength and workability were obtained. The results indicate that the compressive strength and slump of GHPC are affected by various mix proportion factors with different sensitivity, and the sensitivity could be well analyzed by the grey relational analysis. Among the four selected parameters of mix proportion such as water to binder ratio, cement dosage, fly ash dosage and sand ratio, the water to binder ratio and the cement dosage greatly influence on the compressive strength of GHPC, the water to binder ratio and the sand ratio greatly influence on the workability of GHPC.
