Abstract

The influence of zeolite powder on humidity, autogenous shrinkage and mechanical properties inside the self-compacting concrete as the self-curing material are researched. The addition amount of zeolite powder is 0%, 2%, 4% and 8% respectively, the results show that self-compacting concrete with zeolite pow-der as self-curing materials can improve the slump loss. When addition is 2%, it have influence on compressive strength at early age and less influence at later age. Compared with benchmark self-compacting concrete, when internal relative humidity decreases from 100% to 90%, it takes 4d for benchmark self-compacting concrete while self-compacting concrete with 2%, 4% and 8% zeolite powder respectively takes 6d, 14d and 24d. Self-compacting concrete with zeolite powder addition is 2%, 4% and 8%, autogenous shrinkage of 2d respectively decrease 21.4%, 34.9% and 57.3% and 7d autogenous shrinkage respectively decrease 12.6%, 26.8% and 39.4% compared with benchmark self-compacting concrete.
