HEAT SHIELDING CEMENT COMPOSITION AND HEAT SHIELDING LAMINATE
PROBLEM TO BE SOLVED: To provide a heat shielding cement composition hardly accumulating heat even when directly irradiated with sun rays and having excellent abrasion resistance, capable of being used as a material for paving of drive ways or concrete buildings, and to provide a heat shielding laminate.SOLUTION: There is provided a heat shielding cement composition containing white cement, an abrasion aggregate, a composite oxide-based pigment and water and the abrasion aggregate is an aggregate that has the content of α-alumina of 90 mass% or more and contents of each element of Fe, Ca and K are less than 3 mass% in terms of oxide. There is provided a heat shielding laminate 1 having water permeability and manufactured by laminating a surface layer 2 consisting of the heat shielding cement composition and a base layer 3 consisting of a cement composition containing no abrasion aggregate.
【課題】車道の舗装やコンクリート建造物等の材料として用いることのできる、日光に当たっても蓄熱しにくく、かつ、優れた耐摩耗性を有する遮熱用セメント組成物、及び、遮熱用積層体を提供する。【解決手段】白色セメント、耐摩耗性骨材、複合酸化物系顔料、及び水を含む遮熱用セメント組成物であって、耐摩耗性骨材が、α−アルミナの含有率が９０質量％以上で、かつ、Ｆｅ、Ｃａ、Ｋの各元素の酸化物換算の含有率が３質量％未満の骨材である、遮熱用セメント組成物。遮熱用セメント組成物からなる表層部２と、耐摩耗性骨材を含まないセメント組成物からなる基層部３とが積層されてなり、かつ、透水性を有する遮熱用積層体１。【選択図】図１
