Dab tsi yog qhov txawv ntawm pob zeb pob zeb thiab cov cement slab?
Qhov sib txawv ntawm cov cement thiab pob zeb Txawm hais tias cov ntsiab lus cement thiab pob zeb feem ntau siv sib hloov, cov cement yog cov khoom xyaw ntawm cov pob zeb. Lub pob zeb yog qhov sib xyaw ntawm cov khoom sib xyaw thiab muab tshuaj txhuam. Cov aggregates yog xuab zeb thiab gravel los yog crushed pob zeb; cov tshuaj nplaum yog dej thiab portland cement
Dab tsi yog qhov sib xyaw zoo tshaj plaws rau cov pob zeb pob zeb?
Kev sib xyaw ua ke ntawm 1 feem ntawm cov cement: 2 qhov chaw xuab zeb: 4 qhov sib xyaw ua ke (los ntawm ntim) yuav tsum tau siv rau kev taw qhia. Cov pob zeb yuav tsum tau muab tso rau hauv ib nrab ib teev ntawm kev sib tov.Brickwork - Muab koj cov pob zeb tso rau hauv koj lub trench
Dab tsi yog qhov taw qhia ntawm pob zeb pob zeb?
Ib tug footing yog muab tso rau hauv qab ntawm Frost kab thiab ces cov phab ntsa ntxiv rau saum. Qhov taw qhia yog dav dua phab ntsa, muab kev txhawb nqa ntxiv ntawm lub hauv paus ntawm lub hauv paus. Lub hauv paus T-shaped yog muab tso rau thiab tso cai rau kho; thib ob, cov phab ntsa yog tsim; thiab thaum kawg, lub slab yog nchuav ntawm phab ntsa
