Building Solid Waste Recycled Concrete Carbonation Resistance Research
By using orthogonal experimental method,the carbonation resistance of recycled concrete with waste concrete as coarse aggregate was studied,with water cement ratio,replacement rate of recycled coarse aggregate,and fly ash content as influencing factors.Intuitive analysis method is used to analyze the carbonization depth of different factors at different ages,and range analysis method is used to deter-mine the overall optimal level combination.The results indicate that under the influence of a single factor,the increase in water cement ratio,replacement rate of recycled coarse aggregate,and fly ash production will all increase the carbonation depth of recycled concrete based on building solid waste.Among them,the water cement ratio has the most significant impact on the carbonation depth of building solid waste and recycled concrete.When the water cement ratio is 0.5,the replacement rate of recycled coarse aggregate is 25%,and the fly ash content is 10%,the carbonation resistance of the recycled concrete based on building solid waste is the best.
