用板は凍害を受は易いという問題があった。[Background technology 1] The performance required for construction boards is to have excellent frost damage resistance, light weight, and high strength. For this reason, the pore size distribution of the mixed material is such that it contains many particles with a particle size that is difficult to cause frost damage. By making the material distributed and creating voids to reduce weight,
It is conceivable to increase the strength by increasing the lk density. For this reason, in the past, aggregates such as perlite and shirasu balloons were mixed into cement compositions and pressure-formed to produce architectural boards, but the strength of the aggregate itself was low and the bones were difficult to form during pressure-forming. The material is broken! Not only is it not possible to reduce the weight of the material due to L, it is not possible to ensure the strength, and although the particle size is such that it is not susceptible to frost damage, the obtained construction board is easily susceptible to frost damage due to its high water absorption. There was a problem.

A foamed glass aggregate 2 having closed cells 3 is mixed into this cement composition 1. This blending ratio may be a normal mixing ratio of 1 part of this cement composition and 2 parts of foamed aggregate.
After mixing and kneading the mixture with an admixture and water, it is packed into a mold, pressure-molded at a pressure of, for example, 80 kBf/as'' or more, demolded, and cured to obtain a construction board A.

。[Effect of the invention 1 In the present invention, foamed glass aggregate is mixed into the cement composition and pressure molded, so that it can be thoroughly densified, and furthermore, foamed glass aggregate is mixed into the cement composition. Because of this, foamed glass aggregate is pressure resistant and will not break even when pressure molded, making it possible to reduce weight.Furthermore, foamed glass aggregate has fine closed cells. Because of this, it has low water absorption and excellent frost damage resistance.
As described above, according to the present invention, it is possible to manufacture a construction board that has excellent frost damage resistance, is lightweight, and has high strength.
