Cov yam ntxwv ntawm cov txheej txheem yooj yim uas cuam tshuam qhov twg B15 pob zeb siv yog qhov muaj zog. Tag nrho lwm yam khoom yuav tsuas yog nyob ntawm seb hom kev sib xyaw siv. Piv txwv li, nyob rau hauv tsawg cement concentrations, hardness qhov tseem ceeb yuav txawv. Qhov ceev ntawm xws li ib tug muaj pes tsawg leeg yog characterized mus rau ib tug ntau dua los ntawm muab tub lim, uas yog ntxiv nyob rau hauv daim ntawv ntawm txiv qaub, gravel los yog crushed granite. Qhov kev xaiv tom kawg yog suav tias yog qhov kim tshaj plaws, yog li ntawd, B15 pob zeb tsis tshua muaj ua nrog nws siv. Tus nqi hauv qhov no nce ntau. Yog tias koj ua raws li daim ntawv qhia nruj me ntsis, ces cov ntsiab lus ntawm ntau yam impurities thiab lwm yam suav nrog raug cais tawm thaum lub sijhawm ua noj.
Tsis zoo li hnyav analogues, B15 pob zeb xyaum tsis tas yuav suav nrog cov khoom siv tshwj xeeb. Qhov no tsis tsuas yog siv rau cov khoom xyaw uas tiv thaiv qhov sib xyaw ua tiav los ntawm khov. Lub zog ntawm qhov muaj pes tsawg leeg yog suav tias yog txaus rau kev tsim kho ntawm pob zeb screeds, kev tsim kho ntawm lub hauv paus thiab txoj hauv kev. Feem ntau nws yog siv nyob rau hauv kev tsim ntawm txoj kev slabs, raws li zoo raws li FBS blocks. Hauv kev tsim kho tus kheej, nws nquag siv thaum nchuav ntau hom hauv paus thiab erecting utilitythaj chaw.
Txog hnub no, chav kawm B15 pob zeb tau dhau los ua ib qho nrov tshaj plaws hauv kev tsim kho qis. Nws yog nws uas dhau los ua tus pabcuam tseem ceeb hauv kev tsim kho vaj tse hauv nroog suburban, muab qhov zoo heev rau tus nqi me me. Yog li, lub ntsiab kom zoo dua ntawm cov pob zeb sib xyaw ntawm cov chav kawm no yog kev sib piv pheej yig nrog cov yam ntxwv zoo heev.
Thaum tus kheej tsim lub tsev lossis lwm lub tsev, qhov feem pua ntawm cov khoom siv los npaj cov sib tov yuav tsum paub. Lub proportionality ntawm tag nrho cov Cheebtsam plays ib tug tseem ceeb luag hauj lwm nyob rau hauv lub hauv paus txheej txheem, vim hais tias nws ua raws li lub hauv paus ntawm txhua lub tsev. Txhawm rau kom lub neej ntev ntawm tag nrho cov qauv, koj yuav tsum tau saib xyuas lub hauv paus los ntawm kev npaj B15 pob zeb kom raug. Strip foundations muaj qhov zoo, tab sis muaj cov kev xaiv nyob rau hauv daim ntawv ntawm cov pob zeb pob zeb los yog blocks.
Cov khoom sib xyaw ua ke muaj xws li: dej, muab tub lim thiab khi. Cov khoom xyaw kawg yog cov cement. Tau txais cov khoom muaj txiaj ntsig zoo tsuas yog tuaj yeem lav tau los ntawm M200 hom thiab siab dua, txawm hais tias M150 yog qhov tsim nyog rau lub tsev me me hauv lub tebchaws. Raws li txoj cai, rau ib chav tsev ntawm cement muaj peb mus rau plaub units ntawm xuab zeb thiab tib tus nqi ntawm cov muab tub lim. Thaum cov pob zeb B15 tab tom npaj, cov ntsiab lus ntawm lwm cov impurities nyob rau hauv daim ntawv ntawm cov nyom, av thiab lwm yam txawv teb chaws tsis raug tso cai. Zoo dua nrog lub pob zeb sib tovdo cov sib tov zoo. Manually ua tiav cov txiaj ntsig zoo yog teeb meem heev. Tag nrho cov khoom uas muaj nyob rau hauv muaj pes tsawg leeg yog cov ntaub ntawv ntawm txawv grain loj, uas yuav tsum tau sau tag nrho cov voids tusyees.
