摘要：

The carbonation of wetted powders of beta‐dicalcium silicate (β·2CaO·SiO2=β‐C2S) and tricalcium silicate (3CaO·SiO2= C3S) was studied as a function of reaction conditions. The water/solids ratio is an important parameter and there is an optimum value for each silicate. Relative humidity and the partial pressure of CO2 also strongly affect the reaction. The rate of carbonation can be conveniently represented by plotting the degree of carbonation against the logarithm of time. C‐S‐H and calcite are the initial reaction products. Subsequently, carbonation of the C‐S‐H produces silica gel, whereas aragonite may form if the system is allowed to dry out. Copyright © 1979, Wiley Blackwell. All rights reserved
