Dothi lomwe lili ndi dothi limawonedwa ngati choletsedwa kwambiri pamachitidwe achikhalidwe a zinthu za konkriti. Mwachidziwitso, pamene matope ali oposa 3%, mphamvu ya mankhwalawa idzachepa mofanana ndi kuwonjezeka kwa matope. Chovuta kwambiri kutaya zinyalala zomanga ndi zinyalala zosiyanasiyana zolimba ndizosenga. Ndi lamulo lokhwima la chitetezo cha chilengedwe cha migodi ya mchenga ndi miyala, mtengo wa mchenga ndi miyala ukukwera chaka ndi chaka. Pochita ndi zinyalala zolimba, zophatikiza zonse zobwezerezedwanso zitha kugulitsidwa mwachindunji pamtengo wabwinoko. Zotsalirazo zitha kugwiritsidwa ntchito pomanga msana kapena kumanga misewu.

Makina opangira njerwa a Honcha Cinder, ndi mphamvu yodabwitsa ya 360 KNb ndi kugwirizanitsa magwero amitundu yambiri, amalola zipangizo za slag kuti zigwiritse ntchito pafupifupi 8% ya madzi, pambuyo popanga, pamwamba pa zinthuzo zingathenso kusungunuka, konkire imatha kusungunuka kwathunthu, yotopa, kupanga kachulukidwe kwambiri!

Ntchito ya Honcha Yiwu idatsogolera pozindikira kuti slag yonse imathanso kupanga njerwa. Poyesa kupanga njerwa zobiriwira zakale, zida zonse zopanda slag-dothi zimagwiritsidwa ntchito. Zimapezeka kuti kupanga zotsatira zabwino ndi attenuation mphamvu zochepa. Zofunikira zamphamvu zitha kukwaniritsidwa pongosintha gawo la simenti kukhala 10%. Kwa zaka zingapo, polojekiti ya Tiger Pit Project ku Shenzhen yakhala ikupanga njerwa kuchokera ku zinyalala zomwe zasinthidwanso ndikutsuka pochotsa zinyalala pamoyo watsiku ndi tsiku kuti apange magetsi. Ndi zofunika zachilengedwe komanso kukwera mtengo kwa kutaya zinyalala, kampani anayesera kusakaniza zinyalala zinyalala kupanga njerwa. Zotsatira zake, mphamvu ya simenti imatha kufika pamlingo womwewo pokhapokha powonjezera zinthu za simenti kuchokera ku 8% mpaka 9%, pomwe kachulukidwe kake kamawonjezeka kwambiri ndipo kuchuluka kwa mayamwidwe amadzi kumafika pazofunikira zazinthu zapamwamba. Huizhou Hongli Project, mosayembekezereka anaunika mchenga wamwala mu ufa wamwala, ndipo matope otsalawo anagwiritsidwa ntchito kuumba njerwa.

The ntchito zotsatira za owerenga ambiri limasonyeza kuti kachulukidwe mankhwala ndi zofunika thandizo kwa mphamvu mankhwala, ndi konkire zonse liquefaction, simenti malowedwe mu ngodya iliyonse ya mankhwala, makamaka mankhwala pamwamba slurry, kupanga mkati kachulukidwe thandizo, kunja matope thandizo, kotero kuti mankhwala kukwaniritsa zofunika zosiyanasiyana khalidwe ndi ntchito zizindikiro.
