Inert khoom yog cov khoom siv dawb-ntws tsis yog xim hlau ntawm lub hauv paus chiv keeb thiab khoom tsim, siv hauv kev tsim kho pej xeem, txoj kev thiab kev lag luam. Nws kuj yog siv rau kev tsim kho vaj tse. Cia peb saib ze dua ntawm cov ntaub ntawv inert: lawv yog dab tsi, lawv siv qhov twg.
Ntau yam ntawm cov ntaub ntawv inert
Cov ntaub ntawv tsis muaj zog yog mined thaum lub sij hawm quarrying, nrog rau kev ua ntawm ntau yam pob zeb. Lawv yog cov ntom thiab ntxeem tau, sib txawv ntawm qhov loj ntawm cov feem. Nyob rau hauv cov ntaub ntawv nplua-grained, qhov luaj li cas ntawm cov seem tsis pub tshaj 5 hli. Scope ntawm daim ntawv thov nyob ntawm lawv cov yam ntxwv. Inert tsev cov ntaub ntawv yog cov khoom tsis-combustible minerals:
- Gravel yog lub pob zeb uas muaj kev suav nrog lwm hom minerals, sib txawv ntawm qhov loj me.
- pob zeb crushed - yog ib lub pob zeb nrog ib feem me me ntawm 5 mm, tau los ntawm crushing.
- Sand yog cov khoom xoob nrog me meqhov loj me, mined hauv dej nyab thiab chaw txua txiag zeb.
- Cov av nplaum nthuav dav - yog cov khoom siv ntau nrog cov feem uas muaj cov qauv ntxeem tau, tau tsim los ntawm kev tua av nplaum lossis slate.
Cov khoom siv tsis zoo yog cov khoom siv pheej yig. Lawv kuj suav nrog tag nrho cov khoom siv ntuj tsim, suav nrog chalk, av nplaum thiab plhaub pob zeb. Lawv tau siv rau ntawm qhov chaw tsim kho hauv cov ntim loj thiab tuaj yeem txo tus nqi ntawm kev tsim kho. Cov cuab yeej tshwj xeeb yuav siv rau kev khawb av.

Cov khoom siv tsis zoo yog cov khoom siv raw siv los ua cov khoom siv pheej yig hauv asph alt thiab pob zeb mortars, nrog rau hauv cov khoom sib tov qhuav. Cov khoom siv ntau yog siv rau hauv qhov chaw hauv qab no:
- thaum npaj lub vaj thiab thaj chaw uas nyob ib sab, hauv kev tsim toj roob hauv pes;
- rau theem saum npoo lossis muab nws nyem raws li kev teeb tsa;
- rau kev tso cov kua dej, kev sib txuas lus thiab kev tso dej;
- kev tsim vaj tsev nyob, chaw tsim khoom thiab ntau yam qauv;
- hauv kev tsim kho txoj kev thiab kev tsheb ciav hlau;
- rau qhov ntxhib thiab ua tiav ntawm qhov chaw, hauv kev tsim cov vuas ceramic.
Cov khoom siv hauv tsev tau yooj yim xa mus rau qhov chaw tsim kho los ntawm cov tsheb ntawm ntau lub peev xwm nqa tau. Lawv raug thauj nyob rau hauv tej los yog xa nyob rau hauv lub hnab. Qee hom khoom siv inert, xws li xuab zeb, yuav tsum tau ua ntxiv ua ntejxav siv. Los ntawm kev ntxuav, cov impurities txawv teb chaws raug tshem tawm ntawm cov xuab zeb, thiab sieving tso cai rau koj cais cov feem loj.
Yuav ua li cas xaiv cov ntaub ntawv inert?
Inert cov ntaub ntawv hauv tsev yog lub hauv paus rau kev tsim kho ntiag tug thiab kev lag luam. Qhov zoo ntawm kev ua haujlwm ncaj qha nyob ntawm qhov kev xaiv raug ntawm cov khoom siv hauv tsev. Cov khoom no lossis lwm yam khoom ntawm cov khoom ua rau lawv xav tau hauv qee qhov chaw. Vim Frost tsis kam, crushed pob zeb yog siv rau nteg lem, npaj railway embankments thiab toj roob hauv pes. Nws yog tsim nyog raws li ib tug muab tub lim thaum pouring lub hauv paus uas muaj peev xwm tiv taus nce loads. Granite kev tshuaj ntsuam yog ntxiv rau asph alt qhob thiab paving slabs. Cov pob zeb-xuab zeb sib tov yog qhov zoo rau kev ua kom thaj chaw, nrog rau kev tsim cov pob zeb ntxiv.
Recycled Inert Materials
Cov khoom siv rov ua dua tshiab yog cov uas tau rov qab siv dua. Lawv tau ua tiav ntxiv, xws li crushing, thiab khaws lawv cov yam ntxwv qub. Kev siv cov khoom siv rov ua dua tshiab tuaj yeem txo cov nqi tsim kho. Cov khoom siv hauv tsev thib ob suav nrog:
- asph alt chips;
- sib ntaus sib tua ntawm pob zeb thiab cib;
- secondary rubble.
Asph alt crumb yog tsim rau kev tsim kho ntawm txoj kev ib ntus, npaj qhov chaw, backfilling potholes thiab pits. Kev sib ntaus sib tua ntawm pob zeb yog tsim nyog rau kev npaj cov chaw nres tsheb thiab cov chaw tsim kho, backfilling ntawm reservoirs. Secondary crushed pob zeb yog siv los sau cov khoom siv dag zog,kev npaj ntawm txoj kev thiab "alpine toj". Cib sib ntaus sib tua yog tsim rau sau lub gabion, nyob rau hauv lub screed, raws li zoo raws li nyob rau hauv toj roob hauv pes tsim.
