WEAR-RESISTANT PLATE AND MANUFACTURING METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a wear-resistant plate that is hard to be worn even in applications such as coastal structures or river structures, and has excellent wear resistance.SOLUTION: Provided is a wear-resistant plate made of a concrete having a compressive strength of 80 N/mmor more, which is a hardened body of a cement composition that comprises: a binding material that contains at least cement, silica fume, and a filler having a larger particle size than the silica fume; a fine aggregate; a coarse aggregate; and water, and in which the ratio of the coarse aggregate in the cement composition is 20 volume% or more and the mass ratio of water/the binding material is 0.18 or less, as well as having a thickness of 18 to 100 mm.SELECTED DRAWING: None
【課題】海岸構造物や河川構造物等の用途においても磨耗が生じ難い、優れた耐摩耗性を有する耐摩耗版を提供する。【解決手段】セメント、シリカフューム、及び、シリカフュームに比べて大きな粒度を有するフィラーを少なくとも含む結合材と、細骨材と、粗骨材と、水を含むセメント組成物であって、セメント組成物中の粗骨材の割合が２０体積％以上であり、水／上記結合材の質量比が０．１８以下であるセメント組成物の硬化体である、圧縮強度が８０Ｎ／ｍｍ２以上のコンクリートからなり、かつ、厚さが１８〜１００ｍｍである、耐摩耗版。【選択図】なし
