Taariikhda Boostada:10,Oct,2023
Waxqabadka sare ee superplasticizer-ka oo ay matalaan polycarboxylate superplasticizer wuxuu leeyahay faa'iidooyinka maadada hoose, heerka dhimista biyaha sare, waxqabadka wanaagsan ee haynta iyo hoos u dhigista, iyo polycarboxylate superplasticizer superplasticizer wuxuu leeyahay qadar go'an oo keena, taas oo ka dhigaysa dareeraha, caabbinta dhaxan iyo xajinta biyaha. oo shub ah oo ka wanaagsan caaga-dhaqameedka. Sababtoo ah habka isku-dhafka kala duwan ee polycarboxylate superplasticizer, tayada wax soo saarka ee soosaarayaasha kala duwan ayaa aad u kala duwan, oo ay weheliso habka wax soo saarka, sababtoo ah isbeddelka tayada alaabta ceeriin ee la taaban karo, isbeddelka biyaha ee ciidda, qaladka nidaamka cabbiraadda iyo sababo kale, taasoo keentay in shaqada aan degganayn ee isku dhafka ah ee la taaban karo (fudud in la kala saaro ama luminta luminta degdeg ah) ee habka dhismaha ee polycarboxylate superplasticizer. Xataa ma buuxin karo shuruudaha dhismaha. Sida loo doorto polycarboxylate superplasticizer kaas oo ay fududahay in la xakameeyo oo ay fududahay in la soo saaro tayada xasilloon waa mid ka mid ah qodobbada muhiimka ah ee lagu gaaro tayada xasilloon ee shubka.
Xulashada polycarboxylate superplasticizer marka lagu daro imtixaanada waxqabadka aasaasiga ah, sida nuxurka adag, heerka dhimista biyaha, haynta slump iyo imtixaanada waxqabadka kale, dareenka polycarboxylate superplasticizer waa in la tijaabiyaa si loo qiimeeyo tayada polycarboxylate superplasticizer.
(1) Ogaanshaha dareenka beddelka qiyaasta
Hagaajin saamiga isku dhafka la taaban karo ee tijaabada si ay u sharxaan in shaqada iyo haynta slump ee isku dhafka la taaban karo ay buuxiyaan shuruudaha, ilaali qiyaasta alaabta ceeriin ee kale ee shubka ah oo aan isbeddelin, kordhi ama hoos u dhig qaddarka isku-darka 0.1% ama 0.2% siday u kala horreeyaan, iyo ogow hoos u dhaca iyo balaadhinta shubka siday u kala horreeyaan. Farqiga yar ee u dhexeeya qiimaha la cabbiray iyo saamiga isku-dhafka aasaasiga ah, waa yaraanta xasaasiga ah ee isbeddelka qaddarka isku-darka. Waxaa la muujiyay in wakiilka biyaha yareeya uu dareen wanaagsan u leeyahay qiyaasta. Ujeedada ogaanshahani waa in laga hortago xaaladda isku dhafka la taaban karo ee isbeddel degdeg ah sababtoo ah qaladka nidaamka cabbirka.
(2) Ogaanshaha dareenka isbeddelka isticmaalka biyaha
Sidoo kale, iyadoo lagu saleynayo saamiga isku-dhafka ah ee isku-dhafka shubka ah marka uu buuxiyo shuruudaha, qadarka alaabta kale ee cayriin ayaa weli ah mid aan isbeddelin, isticmaalka biyaha ee shubka ayaa kordhay ama la dhimay 5-8kg / mitir cubic siday u kala horreeyaan, taas oo ah, isbeddelka Waxyaabaha biyaha ciidda ku jira waxaa lagu sawiray 1%, iyo hoos u dhaca iyo ballaarinta isku dhafka shubka ah waxaa loo cabbiraa siday u kala horreeyaan. Farqiga yar ee u dhexeeya isku dhafka la taaban karo iyo saamiga aasaasiga ah ee isku dhafka ah, ayaa ka sii wanaagsan dareenka isticmaalka biyaha ee yareeyaha biyaha. Haddii isbeddelka isticmaalka biyuhu aanu ahayn mid xasaasi ah, way sahlanaan kartaa in la xakameeyo wax soo saarka.
(3) Tijaabi la qabsiga alaabta ceeriin
Iska ilaali saamiga isku dhafka aasaasiga ah oo aan isbeddelin, beddel alaabta ceeriin ee la taaban karo, siday u kala horreeyaan u tijaabi isbeddellada slump iyo ballaarinta isku dhafka la taaban karo ka dib isbeddelka, oo qiimee caalaminimada la qabsiga alaabta ceeriin.
(4) La qabsiga isbedelka heerkulka
Iska ilaali saamiga isku dhafka aasaasiga ah oo aan isbeddelin, siday u kala horreeyaan u tijaabi isbeddelka slump iyo ballaarinta isku dhafka la taaban karo ka dib isbeddelka, qiimee caalamnimada la qabsiga alaabta ceeriin.
(5) Beddel heerka ciidda
Kordhi ama hoos u dhig heerka ciidda 1%, u fiirso xaalada isku dhafka la taaban karo, qiimee isbedbedelka cadadka ciidda iyo jayga, iyo in xaaladda la taaban karo ay si weyn isu beddeshay.
