RBP inclusion delayed initial setting time
High RBP replacement with high alkaline solution favored closed porosity, reducing thermal conductivity
RBP was detrimental to strength, but higher activator modulus or Na2O concentration compensated
RBP coarsened pores and increased irregular shapes, worsened by high alkali
