A modification of fabrication techniques for cement paste can significantly affect its properties. Specifically, the static compressive strength can be increased over that of specimens cured under normal temperature and atmospheric conditions. The effects of two fabrication techniques are discussed, the application of elevated temperature and elevated pressure during the initial curing cycle of cement paste, both of which, under the proper time variable, have been shown to increase the measured compressive strength of cement paste. The increase in strength, as high as 23. 2 percent, is shown to be dependent upon the ambient temperature and pressure and the length of time to which the specimens are subjected to these conditions. The effects on sample strength of applying temperatures ranging from 22 - 104 C (72 - 220 F) and pressures ranging from 0 - 1550 kPa gage (0 - 225 psig) were investigated.
