We are doing manufacturing. However, centrifugal force forming11. Approximately 4 to 6% of the concrete 1 waste liquid of product type J, i: is squeezed out.
現在、コンクリート廃液の処理方法としては、薬液によ

しかし、多量に排出されるコンクリ−１・廃液に月して
、今後廃棄場所等の確保が困如］となる状況が予想され
ることから、従来のような廃棄処理方法が行き詰まるこ
とが考えられる。However, given the large amount of concrete and waste liquid that will be discharged, it is predicted that it will be difficult to secure a disposal site in the future, and it is thought that conventional waste disposal methods will reach a dead end. .

。Research and testing on the reuse and utilization of concrete waste liquid has been conducted to date, but very few have been put into practical use due to problems such as cost and the inability to use conventional treatment facilities. If this problem is solved, it will also help with resource and energy conservation issues.
さて、従来の再利用の方法の問題点であるが、それは、

ない点にあった。Now, the problem with the conventional reuse method is that
The manufacturing process involves firing, which costs 14,000 yen per liter in utility costs, and the fired bones must be crushed using a crusher. Ta.
本発明はその問題を解決するものである。The present invention solves that problem.

十分にあり、それだけでコンクリ−１・骨祠として十分
使用できるのではないかと実験を始めた。The present inventor noted that when concrete 1/waste liquid is divided into water and sludge, the cement content is more than 70% of the sludge lll1. ! I started experimenting with the idea that laitance had sufficient hydraulic properties and could be used as concrete and a bone shrine.

The compressive strength of the cylinder fJ1 of 300 to 250 kg/an' was determined to be 111 at 4'' age 28 El as a specimen.

た。Next (20 volumes of fecalized laitance 1 to 51 bones 4)
As part 4, a comparative test with crushed stone was conducted. l m' This January 801~g cement used rat, 10cm x 20
A cylindrical specimen with a diameter of 4 cm was prepared, and the compressive strength of 4) 28 LI was determined. As a result, the result was that Laitance bone No. 4, which was crushed at 205 kg/a and hardened, was almost equivalent to 2011~g/c+u' and could be used as bone 4.4.
なお、３０（１ｋｇ／ｌ・＋１１・までの強度の骨４）

In subsequent tests, it was confirmed that it could be used as bone 44.

, "j′-(The present inventor has obtained crushed sand from Jiang II1, crushed sand,
(using fly ash, etc.) and laitance that had just been dehydrated were added, and the mixer was rotated. The rotation speed is 7
It was 4RPM. By rotating the mixer, the laitance gradually becomes smaller and the corners become rounded, making it almost spherical.
A minute 1;:l child attached to its surface, and it became a bone H at the same time as a movement to prevent other laitances from landing.
It also helps to increase the adhesion of - to concrete 1.

。In addition, if the fine particles were in excess, they would not adhere to the laitance and could be used for the next production.

強度を延ばす小と考えられる。Artificial bone No. 4 of Laitance, which was released in 1999, is approximately 31:
If you put 1 of 1, it has enough strength to mix and add 1. It is thought that the strength of the concrete will be increased along with the concrete that was poured in January.
なＪｊ、レイタンスの人工骨４４の比重は表面乾燥飽水
状態で２．１程度、含水率２１％程度であった。The specific gravity of Laitance's artificial bone 44 was about 2.1 and the water content was about 21% when the surface was dry and saturated with water.
なおコンクリ−１・の重量であるが、砕イ１を使用した
ものと比較して１２％程度軽量化されている。The weight of Concrete 1 is approximately 12% lighter than that using Concrete 1.

る。The J1β shape is also close to a spherical shape with no corners, and has fine bones 4.4! +
Compared to crushed stone and crushed sand, it has a lower capacity of 11.
It is also thought to have an advantageous effect on the amount of cement used, the amount of water used, etc., and lead to a reduction in concrete costs.
