Abstract:
Using recycled brick powder instead of quartz sand to prepare engineering cementitious composites(ECC), the influence of different brick powder substitution rates on the mechanical properties of ECC was studied. Based on the results of mechanical performance tests, recycled brick powder was selected to replace quartz sand 100% to prepare recycled brick powder ECC. The frost-resistance durability of ECC with reference mix ratio and concrete of the same strength grade were compared under different media(water, NaCl solution, Na2SO4 solution, and NaCl Na2SO4 mixed solution)erosion. The frost-resistance durability life of benchmark mix ECC and recycled brick powder ECC under different erosion medium were predicted. The result show that as the substitution rate of recycled brick powder increases, the flexural and compressive strength of ECC gradually decreases. At 100% substitution rate, the flexural strength of matrix is 16.5 MPa and the compressive strength is 33.7 MPa. Under different substitution rates of brick powder, the tensile strain of matrix can reach over 2.5%, and the bending toughness is good. After 300 freeze-thaw cycles, the mass loss rate, change rate of relative dynamic modulus of elasticity, and compressive strength loss rate of C30 concrete are the highest, followed by recycled brick powder ECC, and the benchmark mix ratio ECC is the lowest. The benchmark mix ratio ECC and recycled brick powder ECC both have good salt freezing resistance. Recycled brick powder ECC has a good frost resistance in the “Three North” and the frost-resistance durability life is area, up to more than 90 years in a single freeze-thaw environment and more than 65 years in a single salt freezing environment.
