Study on Influence Factors of Rubber Concrete Compressive Strength

摘要

Rubber is mixed into concrete replacing sand, gravel and both sand and gravel with the same volume. Test compressive strength change trend of 7d and 28d concrete mixed into different volume rubber of 20 mesh, 40 mesh, 60 mesh and 80 mesh and study influence of different way, powder size and dosage on rubber concrete compressive strength. The results show that tenacity, cracking resistance and failure characters of rubber concrete are significantly better than that of ordinary concrete and that compressive strength of rubber concrete declines with increase of rubber dosage.
