Figure 4-17 shows the relationship between the concentration of calcium silicate hydrate (CSH) are packed with CBA20 found that the rate of increase is lower than the CBA0 Low compression. (In the early days of curing, curing or short) and the strength increase CBA20 rate increases are higher than CBA0 clearly during high compressive strength. (In the latter stages of curing, curing or long-term), the third car observed from the graph, the relationship is steeper than the graph CBA20 relationship CBA0.
