Feem 20-40 - crushed granite: nws hnyav, ceev, thiab lwm yam ntxwv

Thaum uas koj ua ntau hom ntawm kho los yog siv ua hauj lwm yuav tsum tau siv ntawm crushed pob zeb. Yuav tsum tau siv rau tej yam hom phiaj, crushed pob zeb ua los ntawm ntau tog. Khoom ntawm loj me me siv tau rau cov hniav hom phiaj, lub ntxhib feem uas yuav tsum tau nyob rau hauv kev tsim kho ntawm ib qho tseem ceeb hnyav khoom.

Qhov nruab nrab luaj li cas ntawm cov fractional - 20-40. Crushed granite ntawm no loj yog lub feem ntau nrov. Quartz diorite los yog granite yog siv rau nws lawm.

cov ntaub ntawv uas muaj pes tsawg leeg

Granite - yog suav hais tias yog feem ntau nyuaj pob zeb, uas yog nyob rau hauv lub ntiaj chaw. Tsaug rau nws cov tshwj xeeb zog, ua los ntawm granite cov ntaub ntawv, xws li gravel, siv qhov kev tsim kho chaw yuav tsum tau raug thaum lub sij hawm kev lag luam rau siab loads. Thiab vim hais tias cov granite pob zeb yog thoob plaws nyob rau hauv yuav luag tag nrho cov xeev, tus nqi ntawm cov ntaub ntawv los ntawm nws tseem mus siv cuag thiab nrov.

Xim ntaub ntawv nyob rau hauv dab tsi minerals muaj granite, tiam sis feem ntau nws muaj coloring los ntawm liab los grey. Tom qab kev sib cuag nrog ib tug me me npaum li cas ntawm cov zaub mov tsaus khoom tej zaum yuav muaj ib tug mottled tsos.

cov ntaub ntawv uas cov kev pab cuam

Feem 20-40 - crushed granite, uas yog suav hais tias yog qhov zoo tshaj plaws muab tub lim rau qhov kev siv sector. Tsaug rau nws siv tau tsis tau los xij sau nyob rau hauv lub tsim nyog cov ntaub ntawv, txuag, thiab heev ho, kim pob zeb hmoov sib tov. Txij li thaum grain granite muaj ib tug ntxhib tws daim ntawv no, zoo heev adhesion tshwm sim Cheebtsam, uas saib kuas zoo heev adhesion ntawm cov khoom tivthaiv.

Thaum piv rau lwm yam tog ntawm qhov luaj li cas, nws yog qhov nruab nrab grain tsim nrog tus nqi qis tshaj zog cov nqi, uas saib kuas lub feem ntau mus siv cuag cov ntaub ntawv uas cov nqi.

zog

Performance nyob rau nram qab no cov khoom:

1. Feem 20-40 - crushed granite, uas muaj lub siab tshaj plaws coj kuj thiab tuav.
2. Cov ntaub ntawv uas yuav mas ib txhis tus naj npawb ntawm freeze / thaw thiab tsis tawg ua me me.
3. Lub xub ntiag ntawm tsawg flakiness. Cov yuag tag nrho ntawm lub ntsis nplej uas muaj ca nrhiav, rab koob thiab thiaj li yooj yim compacted gravel tej nyob rau hauv designs thiab mortars.
4. crushed granite 20-40 Ceev nyob rau tus yug los ntawm uas nws tau ua. Piv txwv li, ib lub voos xwmfab ntawm cov ntaub ntawv uas cov granite nyhav txog 1370-1400 kg ntawm limestone - 1280, gabbro-diabase - 1440 kg.
5. Me porosity. Cov yuav luag tiav qhaj ntawv los ntawm pores tswj siab bandwidth thiab muaj dej haum coefficient.
6. Tsis tshua muaj radioactivity. Qhov no zoo yog ib qho tseem ceeb heev, vim hais tias nws tso cai rau koj siv cov ntaub ntawv uas nyob rau hauv kev tsim kho ntawm lub tsev vaj tse, coj mus muag, pej xeem thiab industrial. Qhov no muaj pes tsawg tus kuj muaj xws li kindergartens, cov tsev kawm ntawv thiab tsev kho mob.

raws li GOST

Nyob rau Crushed granite 20-40 GOST 8267-93 qhia tus naj npawb ntawm cov nram qab no ntsuas:

• 5-23% flakiness;
• nyob rau hauv muaj pes tsawg leeg yuav tsum tsis txhob yuav ntau tshaj 0.5% ntawm lub grain yog 5 hli thiab ntau tshaj 10% ntawm cov zauv feem uas yog me dua 20 mm.
• av nplaum hmoov av yuav tsum tsis txhob ntau tshaj 0.3%;
• Kab 1000-1400 zog;
• luj ntawm 1 m3 ntawm crushed granite 20-40 - 1.35 tonnes;
• xub ntiag ntawm nais ntawm av nplaum - nyob 0.25%;
• lub xub ntiag ntawm mos pob zeb hais - tsis muaj ntau tshaj 5%;
• loj loj ceev ntawm txog 2.7 g / cm ^3;
• endurance - qhia I1.
• qhov feem pua ntawm cov dej haum - ib tug tshaj plaws ntawm 0.4%.

Nyob rau hauv tas li ntawd, cov ntaub ntawv uas yuav tsum muaj cov nram qab zog:

1. Qhov taw qhia ntawm te kuj - F300.
2. radioactivity theem yuav tsum tsis txhob ntau tshaj 370 Coj / kg.

Thaum lub sij hawm qhov kev txiav txim ntawm cov khoom zoo ntsuam xyuas yuav siv sij hawm qhov chaw nyob rau cov no thiab lwm yam ntxwv ntawm lub rubble.

Scope

Crushed granite muaj chemico-lub zog uas muab ib cov ntaub ntawv uas zoo heev zoo. Nws uas yog txhais grain loj.

Feem 20-40 - crushed granite, uas yog siv:

1. Lub pob zeb ua kev daws teeb meem.
2. Thaum lub sij hawm tsim kho ntawm kev reinforced lug.
3. Thaum lub sij hawm pw ntawm cov me nyuam yaus.
4. Raws li tej ceev rau puag nyob rau hauv lub asphalt ntawv.
5. Yuav kom ntxiv dag zog los yog txoj kev kawm tuab si lug.
6. Thaum nres tsheb ntaus ntawv rau cov tsheb.
7. Rau ib ntus venues uas yuav host qhov kev siv cov khoom.
8. Thaum lub sij hawm tsim kho ntawm lub tram kev kev thauj.
9. Yuav kom harden lub nto nyob rau hauv lub w / e ntawm txoj kev khiav.

purchase nta

Peb yuav tsis tham txog tus txheej txheem ntawm tshaaj thiab cov kev xaiv ntawm cov khoom. Tseem ceeb tshaj, cov khoom tau ntsib tag nrho cov specs, thiab qhov no yog tau tsuas yog hais tias nws muaj raws li qhov uas yuav tsum tau ntawm GOST. Tab sis yog nws yeej tseem ceeb yog cov yam ntxwv uas yog piav nyob rau hauv no rau pej xeem cov ntaub ntawv? Yuav ua li cas tshwm sim yog hais tias tus gravel yuav tsis tau raws li lub saum toj no yuav tsum GOST?

Raws li paub tseeb hais tias los ntawm txoj kev xyaum, cov kev hloov entail deterioration. Piv txwv li, yog tias tiaj nplej nyob rau hauv tag nrho cov luj yog ntau tshaj li qhov tus kws kho tau nrog lawv cov kev siv yog tsawg qhob zoo, thiab tus nqi ntawm qhob mix yuav tau nce, uas ua rau muaj zog them.

Yog hais tias crushed granite 20-40 luj yog me me (los yog loj) dua li yog tsim nyog, yog li ntawd, nyob rau hauv nws muaj pes tsawg leeg, muaj nplej ntawm lwm tog. Yog li, qhov ntau dua qhov nyhav, cov ntau lub tag nrho pawg ntawm cov zoo nplej, thiab vice versa: loj hais nyob ntau qhov chaw, li ntawd, xws rubble yuav luj tsawg.

Yog li ntawd, los yuav cov khoom uas yuav tsis muaj lub xav yam ntxwv, tus purchase yog tsim nyog los xyuas kom meej tias koj muaj cov ntaub ntawv pov thawj, tus kab mob-epidemiological xaus, lub tu yam ntxwv ntawm cov khoom thiab nws phau ntawv hla tebchaws.
