[0016] The first embodiment of the present invention will refer to the attached Figures 1 to 4 to describe.
[0017] like figure 1 As shown in , the brick 10 of the first embodiment can be used, for example, to pave roads. Brick 10 has a rectangular brick body 11 . like figure 2 As shown in , the brick body 11 uses first sand 12, second sand 13, and ceramic aggregate (artificial ceramic aggregate) 14 as aggregates. The brick body 11 is produced from an initial mixture 16 obtained by mixing said sand 12 , 13 and ceramic aggregate 14 with cement (also called “bulk cement”) 15 . The particle size distribution of the first sand 12 and the second sand 13 differs from one another. The second type of sand 13 is coarser than the first type of sand 12 .
[0018] The sand 12 and 13, the ceramic aggregate 14, and the cement 15, which are materials used to manufacture the brick 10, will be described in conjunction with Table 1 shown below.

[0044] A second embodiment of the present invention will now be described. The second embodiment differs from the first embodiment in the aggregate of the initial mixture. The second embodiment will be described focusing on its differences from the first embodiment. Components of the second embodiment that are the same or similar to those of the first embodiment will be given the same reference numerals and will not be described.
[0045] Table 2: Proportions of first sand, second sand, granular ceramics and cement for each particle size.
[0046]
[0047] As shown in Table 2, the brick 10 of the second embodiment uses sand 12 and 13, and granular ceramic 26 as aggregates. Brick 10 is produced from a starting mixture 16 produced by mixing sand 12 and 13 , granular ceramic 26 and cement 15 . The granular ceramic 26 has an absorptivity of 12% or higher. The granular ceramics 26 have many pores to form a porous water-permeable structure. The porous structure of the granul...
example 1
[0056] The mixing of sand 12 and 13, granular ceramics 26, and cement 15 makes the first sand 12 constitute 55.8% by mass of the initial mixture 16, the second sand 13 constitutes 5.3% by mass of the initial mixture 16, and the granular ceramics 26 constitute the initial 14.8% by mass of the mixture 16, the cement 15 constitutes 19.6% by mass of the initial mixture 16. Water W is then added for mixing, and water W constitutes 4.5% by mass of the initial mixture 16 . The initial mixture 16 is then homogeneously mixed in the mash tun 22 . The initial mixture 16 is then poured into the mold 24 and cured to complete the production of the brick 10 .
