Nws tsis muaj qhov zais cia tias txhua qhov nthuav dav tseem ceeb hauv kev tsim kho. Yog tsis muaj qhov no, tsis muaj ib qho chaw ua lag luam, txawm tias ib lub tsev me me, tuaj yeem ua tau. Nws yog ib qho tseem ceeb heev uas yuav tsum tau coj mus rau hauv tus account qhov hnyav ntawm cov khoom siv hauv tsev thaum txhim kho ib lub tsev thiab cov khoom.
yog dab tsi? Ua ntej, nws yuav pab tau zoo heev nrog kev xaiv ntawm cov khoom tsim nyog rau kev thauj mus los. Qhov thib ob, paub txog qhov hnyav ntawm cov khoom siv hauv tsev, koj tuaj yeem xaiv txoj cai nqa cov txheej txheem rau lawv cov kev teeb tsa (yog tias, ntawm chav kawm, lawv xav tau txhua). Ntawm lwm yam, tus nqi no yuav tsum paub txhawm rau txheeb xyuas txhua qhov tsim nyog ntawm lub tsev.
Yog li qhov hnyav npaum li cas thiab qhov ntsuas tau los ntawm qhov twg? Qhov ntsuas no sawv cev rau tag nrho qhov hnyav ntawm cov khoom ib lub cubic meter lossis ib square meter (nyob ntawm seb hom khoom twg peb tham txog). Piv txwv li, yog hais tias peb xav tau lub volumetric luj ntawm pob zeb, ces nws yuav tsum tau ib tug cubic meter, thiab yog hais tias peb xav tau lub volumetric hnyav ntawm slate, ces peb yuav tham txog ib square meter. Nws tseem tsim nyog xav txog tias qhov hnyav volumetric suav nrog txhua yam uas tsis tau sauqhov chaw (cua pores), nyob rau hauv lwm yam lus, nws tsis yog lub net (lub sij hawm "specific" yog siv nyob rau hauv kev tsim kho) uas yog coj mus rau hauv tus account.
Y Ua piv txwv, xav txog qhov hnyav ntawm cov pob zeb crushed, tshwj xeeb yog granite. Granite crushed pob zeb yog cov khoom siv nrov heev siv hauv kev tsim kho ntawm txhua qhov teev.
Thiab, qhov chaw zoo li no yog vim nws cov yam ntxwv siab. Nws yog ruaj, Frost-resistant thiab muaj ib tug grain muaj pes tsawg leeg. Cov nplej no tau nthuav tawm hauv daim ntawv cuboid, thiab nws yog daim ntawv no uas yooj yim tshaj plaws rau kev siv ntawm qhov chaw tsim kho. Lwm qhov tseem ceeb ntawm qhov zoo yog nws qhov hnyav hnyav hnyav. Yog li, granite rubble nrog ib lub ntim ntawm ib lub cubic meter yog kwv yees li 1.4 tons, uas yog qhov qhia tau zoo.
Qhov hnyav hnyav ntawm pob zeb crushed yog tshwm sim los ntawm qhov muaj me ntsis ntawm qhov tsis muaj pob zeb ntawm nws cov nplej. Thiab qhov no yog qhov txiaj ntsig tsis tuaj yeem. Ua ntej, yog tias crushed granite yog siv los tsim txhua yam ntawm lub tsev sib tov xws li pob zeb, ces koj tuaj yeem suav rau qhov tshwj xeeb lub zog ntawm cov khoom tiav. Qhov thib ob, vim tias tsuas muaj cov voids me me xwb, muaj kev txuag tseem ceeb hauv cov cement slurry. Thiab qhov no yog qhov muaj txiaj ntsig dua, tab sis los ntawm qhov kev xav ntawm kev lag luam.
Paub qhov ntsuas qhov ntsuas qhov hnyav ntawm cov khoom siv hauv tsev yuav pab siv nws nrog kev ua haujlwm siab tshaj plaws, suav nrog nws qhov zoo (xws li hauv cov ntaub ntawv ntawm crushed granite) los yog ua taushortcomings.
Nws tsim nyog sau cia tias txhawm rau ua kom yooj yim rau kev ua haujlwm ntawm cov neeg tsim qauv, cov kws tsim vaj tsev thiab cov tsim tsim, muaj cov rooj tshwj xeeb uas qhia txog qhov hnyav ntawm ib qho khoom siv.
Kev tsim ua haujlwm tseem xav tau kev paub txog lwm yam khoom siv: ntom, porosity, Frost tsis kam, thermal conductivity, tshav kub muaj peev xwm, lub zog, hardness, elasticity, dej permeability, thiab lwm yam.
