The cements mixed with 20 wt% NaH_2PO_4 solution required a extremely long time to set, whereas the setting time of the cements mixed with 20 wt% NaH_2PO_4 and 20 wt% DL-malic acid solution were about three minutes, regardless of the difference in α-TCP/TeCP ratio of the cements. The pH of setting cement varied from neutral to weekly alkaline in every combination of powder and liquid. The diametral tensile strengths of all cements immersed in distilled water increased gradually with time, and reached 5 MPa for the ct-TCP/TeCP=2/1 cement mixed with 20 wt% NaH_2PO_4・20 wt% DL-malic acid solution.
