Yintoni ikhonkrithi ekhaphukhaphu?
Ikhonkrithi ekhaphukhaphu isoloko isetyenziswa kwizakhiwo ezininzi zobunjineli, kunye nekhonkrithi ekhaphukhaphu ibhekisa kwikhonkrithi eyenziwe ngokukhanya okurhabaxa kunye neeaggregates ezintle kunye nesamente. Ikhonkrithi ekhaphukhaphu ligama eliqhelekileyo lekhonkrithi enoxinano olungekho ngaphezulu kwe-1950kg/m3. Ngoko ke zeziphi iintlobo zekhonkrithi ekhaphukhaphu ezibandakanyiweyo?
Kukho iintlobo ezintathu eziphambili zekhonkrithi ekhaphukhaphu
1. I-aggregate yekhonkrithi ekhaphukhaphu inoxinzelelo olubonakalayo lwe-800 ~ 1950 kg/m3. I-aggregates elula iquka ipumice, i-volcanic slag, i-ceramsite, perlite eyandisiweyo, i-slag eyandisiweyo, slag, njl.
2. Ikhonkrithi enomgongxo (ikhonkrithi enogwebu, ikhonkrithi ene-aerated), ukuxinana kwayo okubonakalayo 300-1000 kg/m3. Ikhonkrithi enegwebu yenziwe nge-sement slurry okanye i-cement mortar kunye ne-foam ezinzileyo. Ikhonkrithi efakwe umoya yenziwe ngesamente, amanzi kunye ne-arhente evelisa igesi.
3. Ikhonkrithi enkulu (ikhonkrithi eqhelekileyo ye-macroporous, ukukhanya aggregate macroporous concrete) ayinamdibaniso ocolekileyo ekuqulunqweni kwayo. Ubuninzi obubonakalayo bekhonkrithi eqhelekileyo ye-macroporous ukusuka 1500 ukuya 1900 kg/m3, ulungiswe nelitye elityumkileyo, ilitye elithambileyo, kunye ne-slag enzima njenge-aggregates. Uxinaniso olubonakalayo lwekhonkrithi edibeneyo yokukhanya yi 500-1500 kg/m3, yaye ilungiswe ngomnqwazi, ipumice, isitena esaphukileyo, slag, njl. njengee-aggregates.
I-Cie-China.org ngumboneleli okhokelayo wezongezo zekhonkrithi zogwebu obonelela ngearhente yogwebu, superplasticizer,isixhasi samandla ekhonkrithi enogwebu kwikhonkrithi ekhaphukhaphu, Iibhloko ze-CLC. Ukuba ukhangela iarhente yogwebu, nceda uzive ukhululekile Qhagamshelana nathi.
