In addition, by coating or penetrating the surface with a waterproofing agent, the surface of the polymer cement mortar layer can not only significantly improve waterproofness, but also serve as surface decoration and reinforcement, improving weather resistance, etc. Not only does it improve its performance as a frame, but it also improves its quality as an exterior or interior material. In addition, the untreated surface is excellent as a base for spraying, painting, tiling, etc. without penetrating the waterproofing agent.

When the polymer addition effect is less than 5% (weight) for polymer dispersion and less than 0.1% (weight) for water-soluble cellulose ether, it is insufficient, and when it exceeds 15% and 1%, respectively. The upper limit was set because not only was it not recognized that the effect of polymer addition would be further improved, but there was also the possibility that various adverse effects would occur due to too much polymer.

(Function of the invention) According to the present invention, the formwork is constructed by layering lightweight polymer cement mortar on a lightweight heat insulating material with reinforcing material interposed, so the entire formwork is extremely lightweight (for example, the thickness is 3Q
Cm, length 2.8m, width 0°9m (less than 45 in 9), and easy to handle. In addition, since it is a polymer cement mortar, it has strong adhesion even when layered on insulation materials with different properties, and there is no risk of peeling (even if anchors are provided, fewer anchors are required compared to ordinary cement mortar). Of course, there is no risk of chipping or cracking. In addition, when layering polymer cement mortar, the finished flatness is good and the workability is also very good, and there is no risk of it slipping down even if it is moved after layering and before hardening.

The polymer cement mortar of the present invention had a unit volume mass that was much lighter than other mortars in an unhardened state. The air-dried specific gravity was also very light. The water absorption rate is higher than that of ordinary polymer cement mortar, so mortar containing polymer has a water absorption rate of 12%.
Waterproofness is recognized as below. Thermal conductivity showed a very small value, and the insulation effect was excellent. Although its bending strength is comparable to that of ordinary cement mortar, its compressive strength is low, so its brittleness coefficient is small, and it is not brittle, making it suitable for the disposable formwork of this invention. Since it is lightweight, it has a high specific strength in terms of bending strength, is not brittle, and exhibits flexibility, making it more suitable for the disposable formwork of this invention than other cement mortars.

If a mesh or perforated sheet is used as a reinforcing material, the bending flexibility will be even better, and if the surface or surface layer is coated or penetrated with a waterproofing agent, the water absorption rate can be sufficiently reduced. Cement mortar made of solid ordinary aggregate such as silica sand is hard, strong, and brittle, so if copper reinforcement is used, the tensile strength of copper is lower than that of steel, so the copper mesh will be weak under bending load. It stretches, has no reinforcing effect on ordinary mortar, and causes cracks in the mortar.

On the other hand, the polymer cement mortar of this invention
It has excellent flexibility and low compressive strength, follows the elongation of copper under bending load, and bends and deforms in balance with the tensile resistance of copper, so it is less prone to cracking and can withstand bending loads during conveyance and assembly of disposable formwork. It is characterized by being able to sufficiently flex against the impact loads of WJ and WJ, and is less prone to chipping and cracking. m
Even if 1 mesh is used, the reinforcing effect is sufficient. By incorporating polymers and using granulated blast furnace slag, the polymer cement mortar of the present invention has an increased adhesion effect with reinforcing materials,
The integration of both ministries will be ensured.
