Lub Xya hli ntuj 10, 2025 · Dingxi, Gansu
Lintao Xinhao Mining tau tshaj tawm qhov kev sib tw rau kev tsim kho ntsuab ntawm kev tsim cov xuab zeb, nrog rau qhov tseem ceeb yog kev tsim kho txhua xyoo 430,000 cubic meter tsim cov xuab zeb ntau lawm kab, txhawb nqa los ntawm crushing, tshuaj xyuas, thiab cov khoom tiv thaiv ib puag ncig. Lub cev ore yog greyish - daj xuab zeb conglomerate, nrog gravel accounting rau 60% (particle loj 4-40mm), xuab zeb 33%, thiab argillaceous khoom 7%. Qhov project yuav tsum ua kom tiav nyob rau hauv 92 hnub, thiab cov neeg sib tw yuav tsum tuav cov chav kawm II lossis siab dua hauv kev cog lus dav dav rau kev tsim kho, qhia txog kev taw qhia txog kev siv cov peev txheej zoo thiab kev tsim khoom zoo ib puag ncig².
Kev Lag Luam Tseem Ceeb: Qhov project teb rau cov cai ntawm kev tsim ntsuab ntawm cov xuab zeb thiab gravel aggregates nyob rau sab qaum teb sab hnub poob ntawm Tuam Tshoj, muab cov ntaub ntawv tsim nyog rau kev tsim vaj tsev. Nws xav tias yuav txhawb nqa lub regional recycled aggregate peev xwm los ntawm 30%².
2. Kev hloov pauv hauv Ecological Slope Protection: C20 Zaub -Kev Loj Hlob Ua tiav tau ua tiav hauv Handan River Regulation Project
Lub Xya hli ntuj 10, 2025 · Handan, Hebei
Cov nroj tsuag C20- loj hlob pob zeb tsim los ntawm Handan ceg ntawm Jinyu Concrete Group tau ua tiav qhov kev txhim kho hauv Liulei River ib puag ncig kev txhim kho dej. Siv optimized gradation ntawm 10-16mm crushed pob zeb aggregates, nws compressive zog mus txog 22.6MPa (ntau tshaj li ib txwm C10). Los ntawm cov txheej txheem txo alkali tom qab hardening, pore pH tus nqi yog txo kom qis dua 9.0, daws qhov teeb meem ntawm cov nroj tsuag ciaj sia. Tsis pub dhau peb lub hlis, 519 cubic meters ntawm kev tiv thaiv txoj kab nqes ua tiav tiav cov nroj tsuag tag nrho, nrog cov hauv paus hniav nkag mus rau 15cm rau hauv cov txheej txheem txheej txheem, ua ib qho "cog-concrete-subsoil" ecological tiv thaiv system³.
Technical Innovations:
Aggregate Gradation Design: Concentrated pores nyob rau hauv coarse aggregates los pab txhawb cov hauv paus nkag.
Txoj kev tsim kho tshiab: 分次布料 + Lub teeb kev co kom tsis txhob slurry thaiv qhov pores.
Alkali Reduction Scheme: Txau cov tshuaj tov tom qab teeb tsa kom tsis txhob muaj zog thaum ntxov ³.
3. Toj roob hauv pes kho dua tshiab: Shanghai Launches Disney- Sib npaug iav Aggregate Gravel Flooring
Lub Xya hli ntuj 9, 2025 · Shanghai
Qishi Pem Teb Engineering Co., Ltd. tau tshaj tawm gravel polymer art ntxuav xuab zeb flooring, uas yog sib xyaw ntawm cov xim iav pob zeb, siab - cov khoom sib xyaw zoo, thiab cov khoom tshwj xeeb. Nws tuaj yeem hloov kho nrog cov qauv qauv (yam tsawg kawg nkaus 50㎡, xa hauv 2 hnub). Ameslikas siv hauv Disney chaw ua si, cov khoom siv no muaj qhov hnav tsis kam thiab tiv thaiv- cov khoom plam, haum rau kev taug kev toj roob hauv pes, chaw ua si, thiab lwm yam xwm txheej, nrog tus nqi tsuas yog 60% ntawm cov tsoos nyuaj paving⁵.

4. Resource Trading Dynamics: 46,000 Tons ntawm Xuab zeb thiab pob zeb Auction tsis ua hauj lwm hauv Xiangyin qhia txog kev lag luam hloov pauv.
Plaub Hlis 10, 2025 · Yueyang, Hunan
Lub Nroog Xiangyin tau teev tseg 46,297 tons ntawm cov xuab zeb thiab pob zeb pov tseg (34,030 tons ntawm xuab zeb + 12,267 tons ntawm pob zeb) rau kev sib tw, nrog tus nqi pib ntawm 1.6 lab yuan. Thawj qhov kev sib tw ua tsis tiav vim qhov kev cia siab tsis sib xws. Lub batch yog thawj zaug npaj rau kev pov tseg nyiaj txiag, xav kom cov neeg sib tw them 500,000 yuan tso nyiaj. Thaum kawg, nws tau raug muag hauv qhov kev sib tw thib peb ntawm 13.16 yuan / tuj, qhia txog qhov xav tau kev ua kom zoo tshaj plaws hauv cheeb tsam cov xuab zeb thiab gravel mov-xov kev hloov kho mechanisms¹⁴.
Kev lag luam Trend Summary
| Teb | Core Trend | Tsav Factors |
|---|---|---|
| Green Mining | Tsim cov xuab zeb ntau lawm kab + thaiv plua plav tswj | Tightening ib puag ncig txoj cai rau mines |
| Ecological Building Materials | Nroj tsuag ntawm cov nroj tsuag- loj hlob pob zeb kev tiv thaiv kev siv tshuab | Kev thov nruj rau kev tswj hwm tus dej thiab pas dej |
| Kev tsim kho toj roob hauv pes | Tus nqi txo ntawm customized gravel flooring | Kev loj hlob tawg ntawm lub tiaj ua si kev lag luam |

"Gravel yog hloov los ntawm ib qho yooj yim muab tub lim mus rau ib qho 'ecological nruab nrab' - Handan cov nroj tsuag - loj hlob pob zeb kho cov ntug dej, Shanghai lub iav aggregates reshape toj roob hauv pes, thiab Lintao cov mines ntsuab txo cov pa roj carbon monoxide. Txhua lub pob zeb yog rejuvenated los ntawm kev txhawb nqa technology. "
