The purpose of this invention is to propose a laminate that has good adhesion between a cementitious molded body and ceramics, and in particular has significantly improved impact strength by laminating ceramics on a cementitious cellular molded body, and a method for manufacturing the same.

点を改善することはできなかつた。 Cementitious molded products tend to absorb moisture, and cementitious cellular molded products in particular have a high hygroscopicity and must be protected by coating with an exterior material, which has the disadvantage that they are easily damaged during handling or use. In order to improve these drawbacks, a ceramic laminate has been proposed in which ceramics are laminated and reinforced on the surface of a cementitious foam. However, cementitious foams made by simply laminating ceramics do not have sufficient adhesive strength between the ceramics and the foams, and cannot necessarily improve the deficiencies of the foams.

℃の温度が好適である。 An example of this manufacturing method is as follows. Foaming cement slurry is poured into the formwork with or without reinforcement, and it is foamed and hardened.
This is cut into a predetermined size and subjected to steam curing to form a cellular molded product. For example, cement, silica stone, aluminum powder, quicklime, or a slurry mainly composed of cement, such as cement, silica stone, or metal soap, serves as the raw material for this molded body. Thereafter, the surface of the cellular molded body to be sewn is pretreated with hydrofluoric acid or its salt, that is, heat-treated at 400 to 700°C in the presence of hydrofluoric acid or its salt to cause a reaction between the cementitious material and the hydrofluoric acid or its salt. A laminate can be obtained by forming a layer of the material, applying pongee or dip coating to the treated surface, and baking the layer.
The firing temperature is 400 to 1000 as long as it does not damage the base material.
A temperature of 0.degree. C. is preferred.

向上を図つたりすると効果が大である。 Cementitious cellular molded bodies, such as ALC plates (autoclaved lightweight cellular concrete plates), have a thermal conductivity of about 0.1 Kcal/m・℃・hr and are 2.5 to 15 cm thick.
If so, the required level as a heat insulating material can be satisfied. For example, if a rectangular parallelepiped of the ceramic laminate according to the present invention using ALC board as a base material is laid out on the waterproof layer of a flat roof with the ceramics facing upward and fixed to the building frame using mortar etc., it will have water resistance, weather resistance, It is possible to lathe a heat insulating layer of an external heat insulating structure that has strength to withstand damage and fire resistance. In addition, the thickness of ceramics can be adjusted from 0.5 to
If the thickness is about 1 mm, it can be strong enough to withstand walking loads. Furthermore, the density of ceramics is
It is 1.5 to 2.7 g/cm 3 , and higher density is preferable because it has higher strength. The dimensions and shapes of these ceramic laminates for external heat insulation structures can be appropriately selected within a range that is convenient for handling and construction. If the vertical and horizontal dimensions are large, it will be inconvenient to transport and handle, while if the vertical and horizontal dimensions are small, construction will take a lot of effort. The shape is generally a flat rectangular parallelepiped, and when installed, the joints must be closely connected to maintain high watertightness. In addition, when fixing the laid-out laminate with mortar, asphalt, synthetic resin, synthetic resin latex, etc. are mixed into the mortar to improve water resistance, and asphalt, synthetic resin, cement, etc. are mixed into the joints. Bonding and filling with fillers to improve watertightness are highly effective.
