Imeko yeMemetime, ikhonkrithi, nodaka lunokuba nokudida kwabo bakuqalisa, kodwa umahluko osisiseko kukuba i-cenment ngumgubo ovuthayo (udaka lwenziwe ngesanti kunye nesanti, kwaye ikhonkrithi yenziwa Isamente, isanti, kunye negravel. Ukongeza kwizithako zabo ezahlukeneyo, ukusetyenziswa kwabo kwahlukile kakhulu. Nditsho nooShishino osebenza nezixhobo yonke imihla banokudida la magama kulwimi lwe-colloftial, njengoko isamente ihlala isetyenziselwa ukukhomba.
Isamente
Isamente yiqhina phakathi kwekhonkrithi nodaka. Ihlala yenziwa ngelitye, udongwe, amagobolosi kunye ne-silica isanti. Izixhobo ziyatyunywa kwaye zidityaniswe nezinye izithako, kubandakanya i-ore yentsimbi, emva koko ifudumele ukuya malunga ne-2 700 degrees fahrees. Ezi zixhobo, ezibizwa ngokuba yiTleker, ziyi-powder entle.
Unokubona isamente ekubhekiswe kuso njengesamente yasePortland. Kungenxa yokuba yaqala yenziwa eNgilane ngenkulungwane ye-19 nge-Leason Jamo Aspdin, eyayifanisa umbala kumatye esiqithi esivela kwisiqithi saseNgilani.
Namhlanje, isamente yasePortland isesona samentswa lisetyenziswa kakhulu. Yinto "ye-hydraulic" yesamente, ethetha nje ukuba ibeka kwaye ilukhuni xa idityaniswa namanzi.
Ikhonkrithi
Ehlabathini lonke, ikhonkrithi idla ngokusetyenziswa njengesiseko esomeleleyo kunye neziseko zophuhliso phantse naluphi na uhlobo lokwakha. Ihlukile kuba iqala njengomxube olula, owomileyo, emva koko iba lulwelo, i-elasticys enokubangela nakuphi na ukubumba okanye ubume, kwaye ekugqibeleni iba yimpahla eqingqiweyo esifuna ikhonkrithi.
Ikhonkrithi inesamente, isanti, igravel okanye enye into entle okanye ebandayo. Ukongezwa kwamanzi kuvula isamente, engumba onoxanduva lokubopha umxube kunye ukwenza into eqinileyo.
Ungathenga ikhonkrithi elungiselelwe iingxowa ezingxowa, isanti, kunye negraveli kunye, kwaye konke okufuneka ukwenzayo kudibanisa amanzi.
Oku kuluncedo kwiiprojekthi ezincinci, ezinje ngezithuba ze-arping fes okanye ezinye izinto. Kwiiprojekthi ezinkulu, unokuthenga iingxowa zesamente kwaye udibanise ngesanti kwaye uzigqobhoze kwisitya esinamavili okanye esinye isitya esikhulu, okanye u-oda kwikhonkrithi yekhonkrithi kwaye uye wathunyelwa.
Udaka
Udaka lwenziwe ngesamente kunye nesanti. Xa amanzi axutywe nemveliso, isamente isebenze. Ngelixa ikhonkrithi ingasetyenziswa kuphela, udaka lusetyenziselwa ukuboleka izitena, ilitye, okanye ezinye izinto ezinzima zomhlaba kunye. Ukuxutywa kwesamente, ngenxa yoko, ngokuchanekileyo, kubhekisa ekusebenziseni i-clement ukudibanisa okanye ikhonkrithi.
Ekwakhiweni kwesipili se-Brick, udaka ngamanye amaxesha lusetyenziswa phakathi kwezitena, nangona kunjalo kule meko ayisoloko isetyenziswa. Kwimimandla eNyakatho, umzekelo, ukudakasa ngokulula ebusika, ke izitena zinokubambeke kufutshane, okanye isanti phakathi kwazo.
IXESHA LOKUQALA: I-Oct-16 ukuya kwi-2023
