SOIL PAVEMENT MATERIAL
To provide a soil pavement material that excels in quick curability, resistance to frost damage, weeding capacity, and cracking resistance; becomes dense by natural carbonation; and has high strength and weeding effect.SOLUTION: A soil pavement material contains an admixture containing at least one non-hydraulic compound selected from the group consisting of γ-2CaO SiO2, 3CaO 2SiO2, α-CaO SiO2, and calcium magnesium silicate, calcium aluminate with a vitrification rate of 70% or more, a CaO/Al2O3 molar ratio of 1.0-2.7, and an impurity content of 15 mass% or less, a gypsum, and the soil. The non-hydraulic compound contains Li. In the non-hydraulic compound, the content of the Li is 0.001-1.0 mass% in terms of oxide.SELECTED DRAWING: None
【課題】速硬性、凍害への抵抗性、防草性、耐ひび割れに優れ、かつ、自然炭酸化で緻密となり、高い強度及び防草効果を有する土壌舗装材料を提供する。【解決手段】γ－２ＣａＯ・ＳｉＯ２、３ＣａＯ・２ＳｉＯ２、α－ＣａＯ・ＳｉＯ２、及びカルシウムマグネシウムシリケートからなる群から選ばれる１種又は２種以上の非水硬性化合物を含む混和材と、ガラス化率が７０％以上、ＣａＯ／Ａｌ２Ｏ３モル比が１．０～２．７、不純物含有量が１５質量％以下であるカルシウムアルミネートと、石膏と、土壌とを含む、土壌舗装材料であって、前記非水硬性化合物中にＬｉを含有し、前記非水硬性化合物中におけるＬｉの含有率が酸化物換算で０．００１～１．０質量％である。【選択図】なし
