For example, water intervention was indispensable for the hardening of the body and the beginning of the reaction, such as when an alkaline bath solution was used to reduce the radioactivity to almost all waste. This water also has the effect of lowering the viscosity of the arsenic, making it easier to handle. However, after curing, dehydration of free water C in the gun causes cranking, causing problems with the M integrity of the assimilate. Kokutsu 3-Jl, has class 1 water absorption r to prevent urinary stress,
In addition, an assimilation method is used that affects the health of the hydride form by at least 5°C4 (zeolite, etc.).

The water in Keiki alkaline liquid exists in the form of free water and combined water. The name of each species depends on the gamma blackness and pressure brim composition of the carp. In addition, the professor of cranks of solidified materials explains that after hardening, free water evaporates, assimilates converge, and the stress concentration that occurs in the resulting mass is the original "C. Evaporation of free water: #
3, the humidity of the outside air and the moisture content of the solidified body are +
It ends with a sigh. -1 and - If the free water is evaporated before the alkaline water bath is hardened, and the free water is evaporated after hardening, the occurrence of solidification can be prevented. If a mixture of an alkaline water bath, a curing agent, and the above-mentioned rigid substance is mixed with VC in a vacuum and hit with a single blow, the evaporation of free water will be promoted and blocked before the formation of water, resulting in crank-free assimilation.坏?ll-Can be hard-made.

Figure 1 shows the content of free water M in the assimilate and the ignition rate of free water after hardening, per 1 conversion of 11 hardened eggs. From this figure, it is important to keep the degree of vacuum at 4 g torr or less to prevent free water from evaporating and to prevent the occurrence of cracks.
