Description
本発明は、日光に当たっても蓄熱しにくい遮熱用セメント組成物、及び、該遮熱用セメント組成物を用いて形成される道路の舗装等の遮熱用積層体に関する。 TECHNICAL FIELD The present invention relates to a heat shielding cement composition that hardly stores heat even when exposed to sunlight, and a heat shielding laminate such as road pavement formed by using the heat shielding cement composition.
道路の舗装やコンクリート建造物等の表面の温度が、夏季の直射日光によって上昇し、ヒートアイランド現象等が生じることが知られている。
従来、ヒートアイランド現象等の抑制のために、舗装体に種々の材料を配合することが提案されている。
例えば、舗装体の表層部に、可視波長域が吸収を示し赤外線波長域では反射を示す顔料を存在させることによって、太陽熱による路面温度の上昇を効果的に抑制することが提案されている（特許文献１）。
また、舗装体の表層部に、中空微粒子を存在させることによって、太陽熱による路面温度の上昇を効果的に抑制することが提案されている（特許文献２）。
It is known that the temperature of the surface of road pavements, concrete structures, etc. rises due to direct sunlight in the summer, causing a heat island phenomenon or the like.
Conventionally, in order to suppress the heat island phenomenon and the like, it has been proposed to blend various materials into the pavement.
For example, it has been proposed to effectively suppress an increase in road surface temperature due to solar heat by causing a pigment in the surface layer portion of a pavement to absorb in the visible wavelength range and to reflect in the infrared wavelength range (patent) Reference 1).
In addition, it has been proposed to effectively suppress an increase in road surface temperature due to solar heat by causing hollow fine particles to be present in the surface layer portion of the pavement (Patent Document 2).

In recent years, the number of days of midsummer days and tropical nights in urban areas has been increasing, and there is a need for a technology that has a large effect of reducing temperature in order to suppress the heat island phenomenon and the like.
On the other hand, cement compositions such as mortar used for road paving and the like are required to have excellent wear resistance.

According to the heat shielding cement composition whose content ratio is within a specific numerical range, for example, it contains white cement, composite oxide pigment (heat shielding pigment), white aggregate and water, and wear resistance. Compared with cement composition for thermal insulation that does not contain agglomerated aggregates, it is less likely to store heat even when exposed to sunlight, and can more effectively suppress heat island phenomenon, etc. The present invention was completed by finding out that the present invention can be applied to paving and the like.
