About /- or more, preferably 800 yu/min 2
It is preferable to use a material selected based on any of the above criteria because the strength can be significantly improved. Examples of materials that meet this criteria include silica, emery, pyrite, magnetite, yellow jade, lawsonite, corundum, zenasite, spinel, beryl, full curb stone, tourmaline, granite, andalusite, and cross stone. , zircon, calcined bauxite,
Heavy burnt silica, boron carbide, tungsten carbide, ferrosilicon nitride, silicon nitride, fused silica,
Examples include electrofused magnesia, silicon carbide, and cubic boron nitride. Also useful are metals that can be machined, such as iron powder, stainless steel powder, and ferromanganese powder. In terms of improving strength, iron powder, austenitic stainless steel powder, and ferromanganese powder are preferable. The reason for this is not certain, but it is assumed that it has high strength itself and excellent adhesion to the cement matrix.

Furthermore, it is also very effective to combine vacuum defoaming treatment and vibration during molding.Curing can be done using different curing methods, such as normal curing, normal pressure steam curing, high temperature and high pressure curing, and temperature curing. Any of the curing methods can be employed, and if necessary, a combination of these methods can be used to obtain a high-strength hardened cement body. Note that the strongest song shows the strength value when it is cured at about 50°C.
