Abstract

This paper describes an experimental research study designed to evaluate the feasibility of usage of the crushed clay brick and concrete block as fine aggregate raw materials producing recycled aggregate infill wall materials. To better understand the influences of various factors, an investigation was carried out with 96 specimens made by regenerated brick granule and concrete block. The regenerated brick granule content (regenerated brick granule and concrete granule proportion), water–cement ratio, aggregate–cement ratio, lime content and aggregate replacement rate were considered in an orthogonal experimental design method (DOE method) involving five factors and four factor levels. The mechanical properties of the recycled aggregate infill wall materials (RAIW) between each factor and level were evaluated by compressive strength, flexural strength and the flexural–compressive ratio. The empirical relationship among mechanical properties and factors of recycled aggregate infill wall materials was proposed by using multivariate regression analysis. The results showed that the water–cement ratio was 0.7–0.8 which is especially effective for improving the compressive strength and flexural strength of recycled aggregate infill wall materials, and the aggregate–cement ratio was the most significant factor in the flexural–compressive ratio.
