Zusammenfassung:	SOLUTION: A ground structure consists of a base consisting of arranged concrete blocks and artificial turf fixed to the base. The concrete block contains cement, sand, and inorganic water retaining materials, and has a water permeability coefficient of 1.0×10-4 m/s or more and 10.0×10-4 m/s or less measured in accordance with JIS A 5371; further, the water retention amount measured in accordance with JIS A 5371 is 0.10 g/cm3 or more and 0.40 g/cm3 or less. The artificial turf is composed of a base cloth made of synthetic resin and having water-passing holes and synthetic resin piles fixed to the base cloth.EFFECT: To provide a ground structure with low temperature rise due to solar radiation.SELECTED DRAWING: Figure 2 【解決手段】グラウンド構造は、配列されたコンクリートブロックから成る基盤と、基盤に固定された人工芝とから成る。コンクリートブロックはセメントと砂と無機保水材とを含み、ＪＩＳＡ５３７１に準拠して測定した透水係数が１.０×１０－４ｍ／ｓ以上で１０.０×１０－４ｍ／ｓ以下、かつＪＩＳＡ５３７１に準拠して測定した保水量が０.１０ｇ／ｃｍ３以上で０.４０ｇ／ｃｍ３以下である。人工芝は、合成樹脂製で通水孔を有する基布と、基布に固定された合成樹脂パイルとから成る。【効果】日射による温度上昇が少ないグラウンド構造を提供する。【選択図】図２
