摘要
Carbonation of non-hydraulic, γ-Ca2SiO4 and CaSiO3, mortars and powders exposed to 100% RH and 100% CO2 environments were studied. The rate of reaction and strength development is faster in γ-Ca2SiO4 than in CaSiO3. Increasing CO2 pressure from atmospheric to 5.62 MPa increases the degree of reaction in both γ-Ca2SiO4 and CaSiO3. Strength increases as a function of degree of reaction and CO2 pressures above 2.00 MPa. The potential use of non-hydraulic materials for CO2 activated cements is discussed. © 1979.
