Study on Reducing Water Absorption of Recycled Aggregates (RAs) by Microbial Mineralization.

As shown in Figure 3 a, comparing the same conservation method, the water absorption of the RAs under the effect of three bacterial liquid concentrations of 1%, 3%, and 5% did not decrease with the increase in the bacterial liquid concentration, but showed a trend of decreasing and then increasing with the increase in the concentration of the bacterial liquid.
