ものではなかった。In general, mortar plastering materials made of cement and sand have poor workability, such as peeling when troweling a wall surface and poor adhesion to the base, resulting in poor workability. Therefore,
Plastering materials made by adding methyl cellulose (MC) or polyvinyl alcohol (PVA) to this mortar have been used.6 [Problems to be solved] However, although this plastering material has improved its adhesion to the base to some extent, it cannot be applied with a trowel. Workability was not fully satisfactory.

The present invention was completed. That is, the present invention is a plastering material consisting of cement, sand, methylcelluloses and oxyalkylene alkyl ether.
以下に本発明の詳細な説明する。The present invention will be explained in detail below.

用可能である。Cement that can be used in the present invention generally includes mixed cements such as early-strength Portland cement, blast furnace cement, and fly ash cement. Sand includes river sand, crushed sand, artificial or natural lightweight fine aggregate, expanded polystyrene granules, calcium carbonate foam, etc.
These can be used alone or in combination. The sand used has a particle size of 5 grains or less. As the methylcellulose, methylcellulose (MC) can be used, and further known analogues such as hydroxyethylmethylcellulose (HEMC) and hydroxypropylmethylcellulose (HPMC) can also be used.

It is used in the mixing ratio of plastering materials. Similarly, oxyalkylene purkyl ether is 0.05 to 50 parts by weight, preferably 0.3 to 50 parts by weight.
3.0 parts by weight. If the amount of oxyalkylene purkyl ether is less than 0.05 parts by weight, the desired effect on workability such as dryness, sagging, and stickiness may not be obtained; Even if it is added to the above, the workability improvement effect will not be improved and it will simply be uneconomical.
