Abstract
By replacing cement with 5% of ground rice husk powder, 4% of corn stalk powder and 30% of fly ash, and replacing natural aggregate with 25% recycled aggregate, the Mechanical Properties of green and environment-friendly self-compacting recycled concrete were studied. The experimental results show that the early strength of the concrete is lower than the common self-compacting concrete. However, the strength of 56 days is up to the design requirement and the volume stability is good. According to the test value of the compressive strength of the concrete block, the curve equation of the relationship between the compressive strength and the age is put forward, and it provides a reference for similar concrete mix proportion design.
