Abstract

In order to offer the condition of plant survival, present the method to reduce pH of porous concrete. Water curing is the most suitable method for reducing pH. Water/cement ratio is lower pH in $25\%$ than $30\%$, and to reduce pH, the larger size of coarse aggregate is more proper in the same water/cement ratio, neutralization management after becoming solid than early.
