| Abstract |
This research explores the engineering properties of reactive powder concrete (RPC) with the following mixtures:
The following mixtures of research:
(1) replacing the weight of silica fume ( 30 %, 50 %, 70 %) by slag.
(2) replacing the weight of cement ( 7 %, 10 %, 15 %,20%,30%) by zeolite.
(3) replacing the weight of cement ( 10 %,20%,30%) by slag.
(4) Integrated replacing the weight of silica fume ( 30 %, 50 %, 70 %) by slag and replacing the weight of cement (10 %,20%,30%) by zeolite.
The results show that：(1)The effects of replacing silica fume by slag on workability have positive impact;(2) The test results of ultrasonic pulse velocity and electrical resistance for RPC show that RPC has good durability and corrosion resistance;(3) The test results of water absorption in each group under a suitably substituted to reduce the overall amount of water absorption is helpful;(4) The test results of compressive strength shows the pozzolanic materials used in RPC has a positive effect. In each group, only the ratio of replacing the weight of cement (20%,30%) by zeolite have significantly lower. Other the ratio of high quartz content is has significantly lower in high substitution of silica fume. |
