Yintoni na eziphathekayo ezinqinileyo

uhlobo ngalunye zokwakha kubandakanya ukusetyenziswa kobugcisa ezithile kunye nezinto. Ngoko ke asisoloko kufuneka imfuneko yokusebenzisa eziphathekayo aqhelekileyo ngokulungiselela yoyilo ezahlukeneyo. Oku ingathathelwa indawo lelinye uhlobo udaka, kulula ukuba ukusebenza kunye nokuveliswa. Kwaye oku ihlangabezana neemeko ezithile eziphathekayo ezinqinileyo. Kwaye lisetyenziswa ngenxa iipropati zabo.

eziphathekayo Idla - uhlobo lwe udaka, apho ipesenti Umatshini usezantsi kakhulu isiqulatho lokufaka. Asinto ixesha elide kakhulu. Kodwa inzuzo yayo ephambili ixabiso eliphantsi kunye lula ufakelo. Ku fanele ukuba udidi enzima izinto B5, V7.5, B10, V12.5, V15. Usebenziso ngokubanzi iye yafunyanwa kwi yabucala kwindlu-isakhiwo, okt. To. Iimpawu zayo amandla kwanele kule ndawo. Kwakhona, le hlobo ngodaka ekuthiwa ubunjwe. Oku kungenxa yokuba yona isoloko isetyenziswa ekwakhiweni kwendlela, t. To. Yena lula nokuqalisa umgaqo irola indlela.

Ukuyondelelana kwendlela umthamo esetyenziselwa amacandelo eziphathekayo wayama ngayo ngu: 1, masilivakalise yesamente, 3 - isanti 6 - lokufaka. Ngoko ukuba axube cc 1 ngokweemitha isisombululo efunekayo 160 kg zesamente, 2200 kg zesanti kunye lokufaka, namanzi zibe ngumqulu seelitha 75. Ngamanye amaxesha imali zesamente kwi plasticizers ezizodwa ezidityaniswe isicombululo. Kubaluleke gqitha ukuqwalasela ukuba okukule amasuntswana ezahlukeneyo zodongwe uthuli kwaye kulo lonke isisombululo khange igqithe-10%. Kungenjalo, umgangatho imveliso ogqityiweyo kuya kuba phantsi. Ngokuxhomekeka kubungakanani lokufaka, eyinxenye ye ngekhonkrithi wayama ngayo, siyahlukana ibe entle-olungisiweyo kunye umxhesho ontlakantlaka-olungisiweyo. Ukubunjwa lokuqala siqulathe zithutha-5 mm, kwaye eyesibini - 40 mm. Emva kokuba ngokuxuba ukuyondelelana yesisombululo kufuneka efanayo emhlabeni umanzi.

kuqamba eziphathekayo iphilile eliquka inani elincinane imixube ibambane lisetyenziswa kwi kulawulo labucala. Ngayo ukwenza isiseko isiseko okanye ubhale screed kwi yoluhlu endlwini. Kudla isetyenziselwa umgangatho sokulinganisa. Kuwo ungakwazi ndakhe udonga, isiseko bands, izithsaba zidlulela, ngokunjalo thina imigangatho, nobhazabhaza womnyango monolithic. Kodwa oku kunokwenzeka kuphela xa kusakhiwa ezisezantsi-suka, okt. A. Xa iimpawu amandla umthwalo ebalulekileyo, nto leyo iba ngekhonkrithi obhityileyo, kusenokuba azanelanga, nto leyo inokukhokelela nemiphumela emibi kakhulu. Ukusetyenziswa kunayo yonke le nto ifumaneka ukwakhiwa kwendlela. Ngayo ukwenza isiseko egangathiweyo igada eziphathekayo.

Ukubeka izinto ndayame kufuneka wenziwe ngokukhawuleza emva kokuba ukulungiswa kunye nokuziswa nto. Ukuba lobushushu okukufutshane udlula degrees 25, ngoko ke isisombululo uqobo wongezelela retarders ukuqaqadeka, ukunciphisa uphuhliso amandla. ithamo yabo ibe ukuya kwi-1% ngokobunzima zesamente ezisetyenziswa isisombululo. Amvumela ukuba ukwandisa ixesha zokuthutha ingqokelela kunye iyure enesiqingatha. Iqondo lobushushu lincinane umsebenzi kufuneka ibe ngaphantsi kwe degrees-5.
