In general, the L material has a compressive strength of around 100 kgf / cm 2 , and the compressive strength of the concrete of the base material is 250 to 30
It was about 1/2 to 1/3 compared to 0 kgf / cm 2, and there was an obstacle such as a dent when a load was applied at a fixed point for a long period of time. Further, the coating thickness is 10 to 30 as described above.
mm, it is necessary to thicken it, and when it is applied to high-rise buildings such as these days, the weight increase due to the SL material increases the weight of the entire building, and beams and the like with even greater bending strength are required, As a result, it also causes an increase in construction costs. If it is applied to an existing building, the beam will be overloaded, leaving a problem in terms of durability. In addition, rust on the metal part is also a problem.

で示される。(2) Oil absorption is 0.05 or less; by using a lightweight aggregate having an oil absorption of 0.05 or less, even if a large amount of the aggregate is added, the self-leveling property is good, and the bone is contained in the resin liquid. It is possible to mix a large amount of the material, and as a result, it is easy to obtain a lightweight SL material having a smaller curing shrinkage rate. Here, the oil absorption amount is an appropriate amount of oil until the adjusted aggregate becomes putty-like, and the amount of linseed oil dropped (cc) relative to the volume of lightweight aggregate (cc).
