Title:
PRODUCTION OF CEMENT MORTAR FORMED ARTICLE
Document Type and Number:
Japanese Patent JP3204329
Kind Code:
B2
Abstract:
PURPOSE: To obtain a formed article having a strength almost equal to that obtained when an asbestos fiber is mixed and lighter than the asbestos fiber- mixed article by mixing a basalt fiber, cement and an aggregate, filling the mixture in a formwork, spraying a synthetic resin and water over the mixture and press-forming the mixture.
CONSTITUTION: A basalt fiber A, cement B and an aggregate C are mixed, the mixture is filled in a formwork, a synthetic resin D and water E are sprayed over the mixture, and the mixture is press-formed to obtain the desired formed article. The fiber A is an inorg. fiber originated in basalt lava and obtained by melt-spinning basalt lava. The length of the fiber A is controlled to 0.1-10mm or preferably to 1-5mm. Although the basalt fiber is used as such, the fiber with the surface coated with a silane coupling agent is preferably used to increase the strength of the finally obtained formed article.
