Research on Additional Water of Mix Proportion for Recycled Aggregate Concrete

摘要

After analysis for the defects and limitations of the existing calculation have been put forward. Regarding the unawareness about a percentage of brick dregs in the recycled aggregate, it designed a test about the water absorption of recycled aggregate with brick dregs and studied the features of water absorption of recycled aggregate with different proportions' brick dregs. Based on the existing calculation methods, it put forward a calculation method of the additional water in the mixing proportion design about the recycled aggregate with brick dregs allocating recycled concrete. It has certain value of application and promotion.
