Description of the Related Art Conventionally, as an acid-resistant and chemical-resistant coating material, an epoxy resin-based resin composition containing silica sand, sand and the like has been mainly used. However, in order to avoid the swelling of the coating film due to the influence of the moisture content of the underlying concrete, in the case of new construction, a sufficient curing period is required after casting the concrete, and an undercoat such as a primer is required.
In addition, since the composition is essentially different from that of cement concrete, the volume shrinkage of epoxy resin with time hardening is different from that of cement concrete. .

合でも弱酸性物質に対しての耐酸性のレベルであった。To solve this problem, there is a two-component type comprising a powder obtained by premixing hard aggregates such as Portland cement and garnet powder and an aqueous acrylic resin emulsion (emulsion). The working time is extremely short, and construction is often impossible, and because the specific gravity of garnet is heavy, aggregates settle after kneading,
There were drawbacks such as uneven distribution of aggregates after application and uneven strength. Also, in order to provide acid and chemical resistance,
The use of a top coat (overcoat material) was essential, and even in that case, the level of acid resistance to a weakly acidic substance was obtained.

の面で、特にクオーツが好ましい。BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail. As a hydraulic cement, Portland cement is 35 to 45% by weight, and metallurgical glass (blast furnace slag) is made into powder and granules in a weight ratio of 55 to 65%.
Use the modified metallurgical glass modified cement. High acid resistance is obtained by this cement denaturation. When the cement weight ratio is 35% or less, the strength of the cured product decreases, and when it is 45% or more, the acid resistance is poor. As the aggregate, powders and granules such as quartz, carborundum, silica sand, garnet, ceramic, and glass are used, and the average particle diameter is 300 to 600 μm.
m is optimal. Among the aggregates, quartz is particularly preferred in terms of colorability, hardness and specific gravity.

なる。However, in the above combination only, when water is added, kneaded and applied to a concrete substrate, the content of Portland cement causing a hydration reaction is low and the content of vitreous is high, so that the mixed water is applied. The water rises on the membrane surface, that is, a bleeding phenomenon occurs, and water required for a complete cement hydration reaction is evaporated and lost to the atmosphere. As a result, (1) water evaporates rapidly into the atmosphere, causing cracks and rapid hardening (deterioration of workability), (2) poor surface quality, (3) poor abrasion resistance, ( 4) The final strength is weak, (5) the chemical resistance is weak, (6) the adhesion to concrete or steel plate is weak, and only a coating film is obtained.

が、一層向上する。Therefore, in the present invention, an aqueous acrylic resin and various additives are blended in order to keep the mixed water until the cement reaches a complete hydration reaction. As the aqueous acrylic resin, a powdery resin having high water solubility such as acrylic acid, methacrylic acid, or a copolymer thereof is used. Further, as additives, generally used defoaming agents for cement, water repellents, flow control agents and water reducing agents, and curing control agents are blended. Thereby, construction workability, self-leveling performance of the coating film, and the like are further improved.

An acid-resistant composite cement composition having water resistance is constituted. The improvements are as follows. (1) The resistance to chloride ions becomes stronger.
