Sandstone ndi thanthwe la sedimentary lopangidwa ndi zidutswa za simenti zokhala ndi mchenga. Ndilo lopangidwa makamaka kuchokera ku nyanja, nyanja ndi nyanja sedimentx komanso pang'ono kuchokera ku mchenga wa mchenga. dongo, chitsulo, gypsum, asphalt ndi zinthu zina zachilengedwe.

Grit ili ndi maubwino angapo osatsutsika:

Kuchulukitsa kukana kutentha kwambiri, kukana chisanu kwambiri komanso kuyamwa kochepa kwa chinyezi;

Kuphatikizika bwino kwa zida zapadera (egconstruction rollers);

Kulumikizana bwino ndi phula ndi simenti mor;

Zizindikiro zowoneka bwino (kukhalapo kwa singano ndi magawo a lamela);

Otsika kwambiri radioactivity ndi mkulu chilengedwe ubwenzi;

Chifukwa chake kufunikira kokonzanso zida zamatawuni ndi zakumidzi;

Mtengo wake ndi wochepa kwambiri, womwe umadziwika kuti umakhudza mtengo wonse kwa wogula.

Gravel giredi M400 ndi M600

M400- Mphamvu zofooka.

Amagwiritsidwa ntchito pomanga misewu, kupanga konkriti wopepuka, zokongoletsa ndi kukongoletsa malo.

M600- Mphamvu zapakatikati.

Zoyenera kupanga misewu, kupanga zomangira zolimba za konkriti ndi konkriti yolemera, kukongoletsa malo, kutsekereza denga, ndi zina.

Derbis

5-20millimeters - gawo labwino kwambiri lofunika kwambiri. Amagwiritsidwa ntchito popanga konkriti ndi zomangira zake, uinjiniya wafoundatin, kuthira zida za mlatho, ma decks a mlatho, misewu ndi mabwalo a ndege ndi maziko.

20-40millimeters-wapakatikati mphambu.Imagwiritsidwa ntchito popanga konkriti, zomangira zolimba za konkriti, kumanga misewu yayikulu ndi njanji, mizere ya tram, komanso kukhazikitsa maziko ndikumanga nyumba zamafakitale.

40-70 millimeters mu gawo lalikulu, ntchito kupanga konkire, strctures lalikulu, ndi kusamalira kuchuluka kwa konkire.Amagwiritsidwanso ntchito pomanga misewu, nyumba zamakampani, ndi zomanga mkati mwa midzi.

Sandtone yophwanyidwa imakhala ndi ntchito zambiri-kuyambira kupanga ndi kukonza konkire kupita ku mapangidwe amtundu.

Zinthu zosagwirizana ndi chinyezi zomwe sizimakhudzidwa ndi nyengo ndipo sizizimiririka chifukwa cha kuwala kwa dzuwa.

Shanvim Industry(Jinhua) Co., Ltd yakhala ikugwira ntchito ndi zida zopukutira & zida zosinthira kwazaka zopitilira 20. Nthawi zonse timayesetsa kupereka chithandizo chodalirika pambuyo pogulitsa kwa kasitomala aliyense. thandizani makasitomala athu kukwaniritsa zolinga zawo zopanga m'njira yabwino kwambiri komanso yotsika mtengo.

Ngati mukufuna mankhwala apamwamba qualiy kuthamangitsa cholinga chachikulu, chonde tiyeni tikuthandizeni ndi njira yabwino kwambiri.
