Performance tests were conducted on concrete with different infiltration crystallization dosages. The influence of the dosage of permeable crystallization on the mechanical properties and durability of concrete is analyzed. The results show that infiltration crystallization has a significant improvement effect on the mechanical properties and durability of concrete. When the infiltration crystallization dosage is 1.2%, the increase in compressive strength, tensile strength, and compressive tensile elastic modulus of concrete reaches its maximum. When the infiltration crystallization dosage is 0.6%, the increase in the ultimate tensile strain value of concrete reaches its maximum. When the infiltration crystallization dosage increases within the range of 0–1.2%, the water seepage height and quality loss rate of concrete decrease to varying degrees, and there is a different degree of improvement compared to the dynamic modulus. The research results can provide reference for the mix design and engineering application of permeable crystalline concrete.

摘要

Performance tests were conducted on concrete with different infiltration crystallization dosages. The influence of the dosage of permeable crystallization on the mechanical properties and durability of concrete is analyzed. The results show that infiltration crystallization has a significant improvement effect on the mechanical properties and durability of concrete. When the infiltration crystallization dosage is 1.2%, the increase in compressive strength, tensile strength, and compressive tensile elastic modulus of concrete reaches its maximum. When the infiltration crystallization dosage is 0.6%, the increase in the ultimate tensile strain value of concrete reaches its maximum. When the infiltration crystallization dosage increases within the range of 0–1.2%, the water seepage height and quality loss rate of concrete decrease to varying degrees, and there is a different degree of improvement compared to the dynamic modulus. The research results can provide reference for the mix design and engineering application of permeable crystalline concrete.
