Sravana Sameeralu Serial 4th Hot Weather

Pasi pemamiriro ekunze ekupisa, kusimbiswa kunoiswa pakutonga kongiri yekumisikidza nguva uye kuderedza unyoro kurasikirwa kubva pakuiswa. Nzira iri nyore yekupfupisa kurudziro yemamiriro ekunze ekupisa kwekuvaka kwepamusoro ndeyekushanda mumatanho (pre-kuisa, kuiswa, uye post-kuisa).

Kufunga kwemamiriro ekunze ekupisa kwekutanga-kuiswa nhanho kunosanganisira kuronga kuvaka, kongiri musanganiswa dhizaini, uye base slab conditioning. Concrete topping masanganiswa akagadzirwa ane yakaderera chiyero chekubuda ropa anonyanya kubatwa neakajairika mamiriro ekunze ekupisa akadai sepurasitiki shrinkage, crusting, uye isingaenderane yekuseta nguva. Iyi musanganiswa kazhinji ine yakaderera mvura-cementitious zvinhu reshiyo (w / cm) uye yakakwirira mafaindi emukati kubva muunganidzwa uye mafiber. Kushandisa yakanyatso giredhi aggregate ine yakakura saizi yepamusoro inogoneka kune application inogaro kurudzirwa. Izvi zvichavandudza kudiwa kwemvura uye kushanda kwemvura yakapihwa.

Kugadziriswa kwechigadziko chebhesi chimwe chezvinonyanya kukosha pakuisa zvipfeko mumamiriro okunze anopisa. Conditioning ichasiyana zvichienderana nekugadzira topping. Bonded toppings inobatsira kubva kune ese tembiricha uye hunyoro mamiriro asi chete tembiricha mamiriro angave akakodzera kufunga kune asina kusungwa slabs.

Zvimwe zviteshi zvemamiriro ekunze zvinotakurika zvinoyera mamiriro ekunze uye zvinobvumira kupinza tembiricha yekongiri kuti ipe mwero wekunyungudika panguva yekuiswa kwekongiri.

Base slab hunyoro hwekumisikidza kweakasungwa toppings inoderedza kurasikirwa kwemwando kubva kumusoro uye inogona kubatsira kurebesa nguva yekumisikidza yemusanganiswa wepamusoro nekutonhodza base slab. Iko hakuna maitiro akajairwa ekugadzirisa base slab uye hapana yakajairwa bvunzo nzira yekuongorora hunyoro hwepamusoro hweiyo base slab yakagadzirira kugamuchira topping. Makondirakiti akaongororwa nezve yavo base-slab hot-weather kugadzirira vakashuma nzira dzakabudirira dzekugadzirisa.

Mamwe makondirakiti anonyorovesa pamusoro nepombi yebindu asi vamwe vanofarira kushandisa washer yekumanikidza kubatsira kuchenesa uye kumanikidza mvura kupinda pamusoro pepores. Mushure mekunyorovesa pamusoro, makondirakiti anoshuma mutsauko wakakura mukunyura kana nguva yekumisikidza. Mamwe makondirakiti anoshandisa washers emagetsi anoenderera nekuisa topping pakarepo mushure mekunyorova uye kubviswa kwemvura yakawandisa kubva pamusoro. Zvichienderana nekuomeswa kwemamiriro ekunze, vamwe vanonyorovesa pamusoro kanopfuura kamwe kana kuvhara pamusoro nepurasitiki uye voimisa kwemaawa maviri kusvika makumi maviri nemana vasati vabvisa mvura yakawandisa nekuisa musanganiswa wepamusoro.

Iyo tembiricha ye base slab inogona zvakare kuda kugadzirisa kana ichidziya zvakanyanya kupfuura iyo topping musanganiswa. Iyo inopisa base slab inogona kukanganisa musanganiswa wepamusoro nekudzikisa kushanda kwayo, kuwedzera kudiwa kwemvura, uye nekumhanyisa nguva yekumisikidza. Kugadzirisa tembiricha kunogona kuve kwakaoma zvichienderana nehukuru hweiyo slab iripo. Kunze kwekunge iyo slab yakavharwa kana shaded, kune mashoma dzimwe nzira dzekudzikisa base slab tembiricha. Makondirakiti ekumaodzanyemba kweUS anofarira kunyorova pasi nemvura inotonhorera kana kuisa musanganiswa wepamusoro husiku kana zvese zviri zviviri. Makontrakta akaongororwa haana kuganhurira topping placements zvichibva pane substrate tembiricha; inonyanya kufarirwa nzvimbo dzehusiku uye mwando mamiriro, zvichibva pane ruzivo. Muchidzidzo chezvivharo zvakasungirirwa muTexas, vatsvakurudzi vakashuma kupisa kwepasi kwe 140 F kana kupfuura munguva yezhizha muzuva rakananga uye vakakurudzira kudzivisa kuiswa kwepamusoro apo substrate tembiricha yaipfuura 125 F.

Kufunga kwemamiriro ekunze ekupisa padanho rekuiswa kunosanganisira kubata tembiricha yekuunza kongiri uye kurasikirwa nehunyoro kubva kune topping slab panguva yekupedzisa. Iwo maitiro akafanana anoshandiswa kubata kongiri tembiricha ye slabs inogona kuteverwa kune toppings.

Uye zvakare, kurasikirwa kwemwando kubva kune kongiri topping kunofanirwa kuongororwa uye kuderedzwa. Panzvimbo pekushandisa online evaporation-rate estimators kana chiteshi chemamiriro ekunze data yepedyo kuverenga huwandu hwekunyungudika, chiteshi chemamiriro ekunze chinobatwa nemaoko chinofanirwa kuiswa pahurefu hunosvika masendimita makumi maviri pamusoro penzvimbo ye slab. Equipment iripo inogona kuyera ambient air tembiricha uye hunyoro hunoenderana nekumhanya kwemhepo. Midziyo iyi inongoda kuve netembiricha yekongiri yapinzwa kuti iverenge otomatiki chiyero chekubuda. Kana mwero we evaporation ukapfuura 0.15 kusvika 0.2 lb/sf/hr, chiito chinofanira kutorwa kuderedza chiyero chekubuda kubva kumusoro.
