Abstract
- This paper studies the influence of stone dust on adaptability of polycarboxylate superplasticizer and cement by the experiment of paste slump and mortar slump flow. The results indicate that polycarboxylate superplasticizer mixed in mortar increases with stone dust mixed because of large specific surface and water demand of stone dust. There is little effect on fluidity loss when the dosage of stone dust is below 18%, and it will increase significantly with the dosage more than 18%. The adaptability of polycarboxylate superplasticizer and cement will be bad when the content of stone dust in manufactured sand is over 10%. The adaptability of polycarboxylate superplasticizer and cement can be evaluated by the method of mortar slump flow.
