The osalimba a mchenga

Sand anthu yaitali kuigwiritsa ntchito pa zomangamanga, popanda nyumba siziri chimodzimodzi kumanga. Iye chimagwiritsidwa ntchito zosakaniza youma zomangamanga, amene amagulitsidwa m'masitolo kapena ngati chigawo cha yokonza matope simenti. Yomanga mchenga umagwiritsidwa ntchito malingana ndi osalimba ake Mwachitsanzo, mitundu ina ntchito kulenga zomangamanga matope, ndi zina kuti apange screed konkire.

Sand - ndi nonmetallic, ndi lotayirira zakuthupi kapangidwe nyumbayi. Childs, chisakanizo cha kukula mbewu ya 0,14-5 mm, yomwe inakhazikitsidwa m'zaka za kuwonongedwa kwa miyala achilengedwe. Pali zingapo mitundu ya mchenga. Iwo yodziwika ndi okhutira osiyana ndi tinthu zabwino dongo kapena kungoti zinthu fumbi.

The choyeretsetsa cha iwo, ndi wapamwamba - izi ndi mtsinje mchenga. M'madzi poipa, popeza kale mbali ya mchere, amene ziyenera kutsukidwa. Dzenje mchenga ndi miyala yodziwika ndi pamaso pa dongo zapathengo, motero khalidwe la mankhwala pansipa. Sand ambiri ali zikuchokera: khwatsi, feldspars, ndi zosafunika mu mawonekedwe a silicates ndi dongo lomwelo.

Pakuti makhalidwe a nkhaniyi nyumbayi pali chinthu monga osalimba a mchenga. Akuti porosity chiŵerengero. Mwachitsanzo, kalasi zabwino adzalandira index wa 0,75. Kachulukidwe yomanga mchenga, ubwino wake nthawi zonse anatsimikiza ndi kukhalapo m'menemo dongo. Kumathandiza akufuna ntchito ndi chiyero wapadera - Mtsinje mankhwala. Iwo ali osalimba a 1.3 T. Per mita kiyubiki. kachulukidwe wa mchenga ndi wokhutira dongo kale pamwambapa 1.8 m. Mu buku chomwecho.

Nkhanizi ndi maziko a zaka zambiri simenti ndi nyimbo konkire. Iwo anafuna kwambiri atagona misewu, ndi zimawombera nkhani galasi ndi ulimi.

Pomanga wofunika kwambiri kwa maganizo osalimba, ndilo chiŵerengero cha unyinji wa mchenga ndi buku wake, ali muyeso wagawo: g / cm3, makilogalamu / M3. Natural kachulukidwe chochuluka cha mchenga ndi 1300-1500 makilogalamu / M3.

Chochuluka zipangizo zomangamanga, chithunzi ichi ndi variable ndi zimadalira mlingo wa compaction. Iwo ankadziwa kuti yofanana mankhwala amatenga ndalama osiyana. Kachulukidwe mchenga mosasintha amadalira chinyezi ndipo aliyense wa Kusiyana kwake kudzakhudza motani kachulukidwe chochuluka. Pa mbewu apamwamba chinyezi ataphimbidwa ndi wosanjikiza madzi ndi mogwirizana ndi kuchuluka kwa ukuwonjezeka mchenga kwambiri. Kuti kachulukidwe chochuluka mchenga wa oscillation chinyezi nkhani pamene kuwerengetsa mlingo wa mchenga voliyumu ankafuna. Ngati mulibe kuganizira chinthu ichi, matope sadzakhala ndi zofunika chitetezo malire ndi akukhudzidwira zomangamanga kapangidwe adzakhala kwenikweni.

Tsopano zimagwiritsa ntchito alluvial mchenga, Tingafinye ake ndi losavuta - kusamba mchenga miyala. Izi zachitika motere: buku waukulu wa madzi therefrom anatsuka dongo ndi fumbi.

kumanga mchenga kachulukidwe zimadalira dongosolo tirigu. Mwachitsanzo, mlingo mkulu wa umboni mwachindunji chakuti mbali ya wandiweyani, wamphamvu kwambiri ndi ozizira zosagwira mbewu yake. Izi ndi nkhani ndi koyefishienti yapamwamba singasiyanitsidwe kwa nyumbayi mu zinthu Madzi oundana. Iye ndi maziko a mkulu-mphamvu konkire, ndi hardiness kwambiri.

Kachulukidwe wa khwatsi mchenga mu mkhalidwe lotayirira yodziwika ndi index wa 1500 makilogalamu / M3, koma angadwale kwa 1700 makilogalamu / M3. Iwo amakhala ndi makhalidwe abwino ukhondo ndi kusamba ndi calcined youma zinthu zachilengedwe. Pamene ntchito yomanga kuonetsetsa mkulu makhalidwe ukhondo kukhala. The kachulukidwe ya mchenga khwatsi - ndi chizindikiro chofunika kwambiri chimene n'komwe pa ntchito yomanga.
