本発明はフンクリートの骨材や、工場排出熱水の循環系
における放熱低下材料として用いられる肉色の人工軽量
骨材に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flesh-colored artificial lightweight aggregate used as an aggregate for Funkreet or as a material for reducing heat radiation in a circulating system of hot water discharged from a factory.
近年、各地で高層建築が盛んとなるに従い、その購吸材
であるコンクリートの軽量化が要求されると共に、骨材
の不足解決の対策としても、人工の軽量骨材が要求され
てきた。この為一部には、軽石の如さ天然のものが利用
されたこともあるが強又と吸水率の点で満足すぺさもの
が安定して入子できなかった。そこで人工的に軽量骨材
ご製造しようとする試みが為され、粘土、頁岩、石炭灰
などを原料として研究が始められた。In recent years, as the construction of high-rise buildings has become popular in various places, there has been a demand for lighter concrete, which is the absorbing material used for these buildings, and there has also been a demand for artificial lightweight aggregates as a solution to the shortage of aggregates. For this reason, natural materials such as pumice have been used in some cases, but materials that were satisfactory in terms of strength and water absorption were not able to be stably nested. Therefore, attempts were made to artificially produce lightweight aggregate, and research began using clay, shale, coal ash, etc. as raw materials.
粘土を原料とする場合には、天然に産する塊を粗砕して
骨材に適する形状、大きさのものを、そのま＼炉で焼成
、発泡させて軽量化する方法が採られており、又、頁岩
を原料とする場合には頁岩を粉砕して１５０μの以下程
度にした後、これに水を加えて：３湿し、造粒、乾燥後
焼成する方法が実用されている。When clay is used as a raw material, the method used is to roughly crush naturally occurring lumps into shapes and sizes suitable for aggregate, then fire and foam them in a furnace to reduce the weight. In addition, when shale is used as a raw material, a method is practically used in which the shale is crushed to a size of about 150 μm or less, water is added thereto, moistened, granulated, dried, and then fired.

共に粘土色ないし：ま黒色である為、化粧仕上げの構築
物（こ対しては、溝築物表面に施工する塗装材の塗布工

ていた。Although the above conventional method significantly improves the weight of the aggregate compared to manufacturing it, since the surface and interior of the aggregate are clay-colored to black, it is difficult to construct a decorative finish. Since the process of applying a coating material to the surface of a trench structure is cumbersome, a lightweight white aggregate has been desired.
又、熱水を放出する工程ごもつ工場では、省工ネルギー
の観点から、これを一時滞留させ潜熱を利用しているが
この場合滞留中の熱放散を防止する為に発泡ポリエチレ
ン等の合成樹脂製のポールを浮遊させ蒸発石抑止させる
ことが多い。In addition, in factories that have processes that release hot water, from the perspective of saving energy, the hot water is temporarily retained to utilize the latent heat, but in this case, synthetic resin such as polyethylene foam is used to prevent heat dissipation during retention. In many cases, evaporite is deterred by floating poles made of wood.
しかしながら合成樹脂製のボールは熱に弱く、耐久性に
欠けるものがあった。更に、従来の骨材を利用してみた
が、色が災いして美観を損なう為利用されにくかった。However, balls made of synthetic resin were sensitive to heat and lacked durability. Furthermore, attempts were made to use conventional aggregate, but it was difficult to use because the color affected the aesthetic appearance.
本発明は前記現状に鑑み、コンクリート骨材や、保温材
として用いることのできる白色の人工軽量骨材の製造方
法を供すること３目的とする。In view of the current situation, the present invention has three objects: to provide a method for manufacturing a white artificial lightweight aggregate that can be used as a concrete aggregate or a heat insulating material.
本発明はこの目的を達するため鉄含有率が１重量％以下
のセリサイトを原料とし、これに炭化硅素と酸ｆヒ錫及
び硼砂からなる群から選ばれた一種以上ビ、内割り重量
％にて炭化硅素は０．１〜１．０％、酸化錫は１．０〜
１０．０％、硼砂は０．０１〜２．０％の範囲で添加し
、造粒して乾燥、焼成することにある。In order to achieve this object, the present invention uses sericite with an iron content of 1% by weight or less as a raw material, and contains at least one type of bicarbonate selected from the group consisting of silicon carbide, an acid, arsenic, and borax in an amount of 1% by weight or less. 0.1 to 1.0% for silicon carbide and 1.0 to 1.0% for tin oxide.
10.0%, and borax is added in the range of 0.01 to 2.0%, and is granulated, dried, and fired.
雰囲気酸素濃度が８〜１３容量％の回転炉で２０〜３０
分焼成して白色の骨材を得ると云うものである。20 to 30 in a rotary furnace with an atmospheric oxygen concentration of 8 to 13% by volume.
It is said that white aggregate is obtained by firing separately.
本発明でセリサイト、長石等の主原料に含まれる鉄の割

中に含まれると、骨材の色調が本発明で提示する白色限
界を超える為である。又、添加剤として炭化硅素、酸化
錫、硼砂の添加量を内割り重量％にて炭化硅素は０．１
〜１．０％、酸化錫は１．０〜１０．０％、硼砂は０．
０１〜２．０％と定めたのは、これらの範囲未満の添加
量ては骨材の比重低減効果が顕著でなく、又これらの範
囲ひ超えた添加量ではその効果が飽和してしまうからで
ある。In the present invention, the proportion of iron contained in the main raw materials such as sericite and feldspar is set to less than 1% by weight because if more iron is contained in the main raw materials, the color tone of the aggregate will change according to the present invention. This is to exceed the white limit. In addition, the amount of silicon carbide, tin oxide, and borax added as additives is divided into % by weight, and silicon carbide is 0.1.
~1.0%, tin oxide 1.0-10.0%, borax 0.
The reason for setting it at 01 to 2.0% is that the effect of reducing the specific gravity of aggregate will not be significant if the amount added is less than these ranges, and the effect will be saturated if the amount added exceeds these ranges. It is.
本発明は、頁岩を主体とする従来の骨材に比較して、鉄
分を下げているため骨材の焼成時に赤褐色や黒色に変化
する恐れがなく白色コンクリートと同系色の色調であっ
てしかも比重の軽いものが得られる。Compared to conventional aggregates mainly made of shale, the present invention has a lower iron content, so there is no risk of the aggregate turning reddish-brown or black when fired, and the color tone is similar to that of white concrete. You can get a light one.
以下に実施例を示す。 Examples are shown below.

After adding in a range of 0.01 to 2%, the mixture was mixed and pulverized using a 0.5 m3 vibrating mill, the humidity was controlled using a known method, and the mixture was granulated using a pan-type pelletizer to give an average particle size of 7 mm. After drying the granules in a hot air circulation dryer for 6 hours, the oxygen concentration is 8~
The mixture was transferred to a rotary kiln with an atmosphere adjusted to 13% by volume, and fired at 1050 to 1200C for 20 to 30 minutes.

す。After firing, it was cooled in a rotary cooling furnace and used as aggregate. In addition, as a comparative example, an aggregate using sericite as the main raw material and silicon carbide as an additive was produced in the same process as the present invention, and as an aggregate that exceeds the scope of the present invention, carbonized aggregate was added to sericite as an internal weight percentage. Aggregate with 0.5-1.0% silicon added and then 0.5-2.0% iron oxide, and then simply 4% iron oxide added.
．． Is it the same process for aggregate with 5% addition? The specific gravity of each aggregate was measured in accordance with the specific gravity and water absorption rate test method for lightweight coarse aggregates for construction in ``Technical Engineering S-A-1135''.The color tone was determined using the color tone comparison standard for white paints. The whiteness was measured using Kataishikawa.Furthermore, the crushing load (average of three pieces) was measured for some of the aggregates.The measurement results are shown in Table 2 and below.

0.17 As shown in the above results in Table 2, the method of the present invention resulted in a white color,
Aggregates with a specific gravity of up to 0.5 were obtained, and aggregates with a crushing strength similar to that of conventional materials were stably obtained.
長石を主原料とした場合も同様な結果が得られた。Similar results were obtained when feldspar was used as the main raw material.

工程が少なくて済むようになった。According to the present invention, a white, light-weight aggregate is easily available, and the pigment application process can be reduced when used in constructions that require a decorative finish.

骨材Ｐ用いることでこの問題も解消された。Furthermore, when used as a floating pole to prevent heat dissipation in a hot water retention tank, it has improved durability compared to conventional synthetic resin balls. Further, conventional aggregates were brown or black, which lowered the appearance value of the hot water retention tank, but this problem was solved by using aggregate P according to the present invention.
