砂浆和糊剂的小样本固化28天，然后经受各种干燥和碳酸化条件。一般而言，对于给定的CO2浓度，碳化的程度取决于渗透性、含水量和时间，但碳化收缩的程度和最终体积稳定性取决于骨料的可压缩性、水/水泥比、浆体的成熟度、干燥环境和速率以及干燥和碳化的顺序。这些结果的一些实际影响。
Summary Small specimens of mortar and paste were cured for 28 days and then subjected to various conditions of drying and carbonation. In general the extent of carbonation, for a given CO2 concentration, depends upon permeability, moisture content and time, but the extent of carbonation shrinkage and ultimate volume stability depend on the compressibility of the aggregate, the water/cement ratio, the maturity of the paste, the drying environment and rate, and on the sequence of drying and carbonation. Some of the practical implications of these results are noted.
