Problems solved by technology

[0005] When performing curing operations, adding these additives by metering will not only cause complicated work, but also cause the problem that the additives cannot be evenly spread over the curing target material or all the cement because the amount of additives added is several to more than 10%.
[0006] Regarding this problem, although all additives can be added in advance, only the required amount can be measured and used on the job site, but at this time there will be a chemical reaction between the additives, which will easily make the solution gel, and also due to the addition of hardened materials , so the curing reaction will be accelerated, and there will be a problem that the curing operation time cannot be ensured sufficiently
[0007] Furthermore, since there are various curing target materials, if the amount of various additives is not properly adjusted at the curing work site, there will be a problem that the required strength cannot be achieved.

Embodiment 1

[0081] A block embodiment of the curing method of the present invention will be described below.

[0082]To 30kg of incineration ash (fly ash, collected at the Cleaning Center of Kawabe Town, Kawabe-gun, Kagoshima Prefecture), 2.4kg of cement (product name: Portland, manufactured by Pacific Cement Co., Ltd.) was mixed with 60cc of 20-fold diluted After A curing agent (61% of lignosulfonate, 36% of sodium silicate, 3% of glucose-containing additive) solution, knead with kneading machine (device name: Pelegaiyer, Kitagawa Iron Works Co., Ltd.) for 4 minutes, then connect After adding 30cc of B curing agent (lignosulfonate 55%, calcium chloride 42%, glucose additive 3%) solution diluted to 30 times, after mixing with a kneader again, inject the kneaded material In the model, a block body with a length of 50mm × width of 50mm × height of 50mm is formed.

[0083] The available block compressive strength is 233kg / cm 2 , The bending strength is 60fkg / cm 2 . In addition, the resul...

Embodiment 2

[0085] To 2kg of incineration ash (coal ash, collected in Kyushu Island thermal power plant) and 0.25kg of aggregate granulated from the incineration ash, add 20cc of A curing agent (lignosulfonate 62%, Sodium silicate 35%, containing glucose additive 3%) solution, obtain the semi-finished product that has kneaded 4 minutes with kneading machine (device name: Pelegaiyer, Kitagawa Iron Works Co., Ltd. manufacture). The semi-finished product is then screened with particle diameters below 2 mm, 2 to 10 mm, and above 10 mm, and then mixed again with a weight ratio of each size of 1.8:1:1, and 0.3 kg of cement (product name: Portland, Pacific Ocean) is added. Cement Co., Ltd.), and after adding 18cc of B curing agent (52% lignosulfonate, 45% calcium chloride, 3% glucose additive) solution diluted to 30 times, knead again with a kneader , inject the kneaded material into the model at 55kg / cm 2 The punch press pressure is compressed into a block body of 50mm × width 50mm × height 50...

Embodiment 3

[0088] Add 3kg of cement (product name: Portland, manufactured by Pacific Cement Co., Ltd.), And after adding curing agent A (62% lignosulfonate, 35% sodium silicate, 3% additive containing glucose) and curing agent B (55% lignosulfonate, 42% calcium chloride, 3% additive containing glucose) , After kneading for 30 minutes with a kneading machine (device name: 25A, manufactured by Davidson Co.), the kneaded material was poured into the mold to form a block body with a length of 198 mm x width of 98 mm x height of 60 mm.

[0089] The available block compressive strength is 352kg / cm 2 , The bending strength is 74fkg / cm 2 .

Abstract

A method for solidifying and the solidifying agent can not noly hoist working performance of solidifying working but also offer materials of kinds of solidifying standard to attain proper solidifying intensity, and its character is: to the admixture of the materials of solidifying standard and calcium group, successively or simultaneously appending solution A which based on admixture of lignin group and sodium silicate and solution B which based on admixture of lignin group and calcii chloridum, solidifying the said materials of solidifying standard by mixing and agitation.

Description

technical field [0001] The present invention relates to a curing method and its curing agent, in particular to the curing method and its curing agent for curing various curing target materials in the manufacture of building materials, paving roads, curing industrial waste, etc. Background technique [0002] In the past, industrial waste such as sludge and incineration ash was solidified with cement, etc., and used as building materials such as blocks or wall panels, or kept in isolation in a solidified state. In addition, when paving roads, use the soil and sand on the paving site, or surface materials for repairing roads, etc., and use them to pave new roads after curing. [0003] When curing these various curing target materials, for example, as Japanese Patent Application No. 2003-171160, discloses methods such as cement, lignosulfonic acid, and calcium chloride used as curing agents; or Japanese Patent No. 5-339935 , to reveal the use of cement, lignosulfonic acid, sodi...
