Construction waste in Our country has a good recycling system, can carry out the production of various recycled building materials. In order to understand the availability of red brick in construction waste, the effect of the content of red brick in recycled aggregate on the physical properties and strength of recycled concrete is discussed to explore whether recycled concrete containing red brick is suitable for application in masonry blocks. The results show that there is no significant correlation between the content of red brick and the compressive strength of recycled concrete, while the slurry strength is positively correlated with the compressive strength of recycled concrete. The strength of recycled concrete can be improved by reducing the water-cement ratio. However, reducing the water-cement ratio will reduce the workability of concrete, which needs to be compensated by adding water-reducing agent. According to the experimental results of unit weight, water absorption, ultrasonic wave velocity and resistance properties of recycled concrete, the content of red brick can improve the porosity of recycled concrete and have a negative effect on durability. The overall experimental results are verified by the relevant specifications, and the recycled concrete containing red brick is suitable for class N block and meets the relevant requirements of the specifications.
