Consider the CBA20 found that at the age of 3 days, and 7 days have its concentration less than CSH CBA0 at the age of 14-day anniversary of assessing the concentration of the CSH increased rapidly until the 28th day is greater than the concentration of the CBA0 rate increases the intensity, aggressiveness, it continues to rise until the age of 90 and 120 day check box.Add the rise of CSH on curing this consistent with the development of compression so that the primary product is CSH affects the development of compression in the soil cement. In addition, bagasse ash in CBA20 also contributed to the increase in concentration, with higher CBA0 CSH which used the plain cement so the ash bagasse contribute add compression, with cement. The concentration of the CSH's CBA0 and CBA20 show details in table 4-7.
