内張り材が必要となっている。SUMMARY OF THE INVENTION Among the above lining materials,
Concrete pipes have problems that they are heavy and have low heat resistance. On the other hand, asbestos slate tubes and asbestos calcium silicate tubes obtained by round netting are relatively lightweight, but have a problem in that asbestos, which is a carcinogenic substance, is used. 2. Description of the Related Art In recent years, the number of cases in which emergency power generators are installed has increased due to the multifunctionality of buildings, and power generation equipment has also been increased in size and performance, and the exhaust gas temperature has become high (400 to 600 ° C.). In addition, regulations on asbestos are strict, and there is a need for a chimney lining material that does not use asbestos and has substantially the same heat resistance as asbestos.

There are clay minerals such as feldspar, frog eye clay and bentonite, and it is particularly preferable to use Kibushi clay. The compounding amount is preferably 5 to 60 parts by weight based on 100 parts by weight of cement.
Addition of clay increases the strength, but if it exceeds 60 parts by weight, the dimensional change after heating increases, and there is a problem in heat resistance. In addition to the above composition, an inorganic filler and a reinforcing fiber may be added.
