Ungazihlola kanjani isilinganiso sokunciphisa amanzi sodaka?

1. Okuqukethwe kwesihloko kanye nobubanzi besicelo

Le ndlela icacisa izinto zokusebenza kanye nezinyathelo zokusebenza zokunqunywa koketshezi lukasimende kasimende.

Le ndlela isebenza ekuzimiseleni komoya wodaka lwe-volcanic ash portland cent, usimende oyinhloko wePortland, usimende ojwayelekile wePortland usimende oxutshwe ne-ash ash, i-slag portland cement kanye nezinye izinhlobo zokwenza usimende ezikhethiwe ukusebenzisa le ndlela.

2. Amazinga Ezethenjwa

Indlela yokuhlola amandla we-GB177

Isihlabathi esijwayelekile se-GB178 sokuhlolwa kwamandla kasimende

I-JBW 01-1-1

I-3. Indlela yokutholwa kwezinga lokuncipha kwamanzi lingumonga olandelayo:

3.1 Izinsimbi nemishini

A. Mortar Mixer;

B. Eqa itafula (ipuleti lengilazi elibanzi le-5mm kumele lingezwe);

C. Cylindrical Raming Bar: Kwenziwe ngezinto zensimbi, ububanzi 20mm, ubude bango-185mm;

D. I-Confung Conse isiyingi isikhunta kanye nesembozo sesikhunta I-Conchaded Cone isikhunta nesikhunta sesembozo esenziwe ngezinto zensimbi;

E. Mbusi (ukulinganisa ibanga 300mm) noma ama-calipers anobubanzi bokulinganisa 300mm;

F. Spatula.

I-G. Ibhalansi yezidakamizwa (enesisindo esingu-1000g, sizwa 1G).

3.2. Inqubo yokuhlola

3.2.1 ukukala ukusetshenziswa kwamanzi kwe-reference kasimende

A. Isisindo esingu-300g usimende kanye nesihlabathi esijwayelekile se-750g bese uwathela ebhodweni lokuxuba, qala i-mixer, engeza amanzi kancane ngemuva kokuxuba ama-5s, bese uwafaka ngaphakathi kwama-30s. Yeka ukushukumisa ama-3min ngemuva kokuqala umshini. Susa udaka ema-blades bese ususa ipani elivusa amadlingozi.

B. Ngokuxuba udaka ngasikhathi sinye, ngendwangu emanzi yokucima itafula letafula, i-raming rod, usike isigaxa sokubumba isigaxa nokubumba kodonga lwangaphakathi, bese uwafaka enkabeni yeplanethi yengilazi, embozwe ngendwangu emanzi.

C. Udaka oluhlanganisiwe luhlukaniswe ngokushesha zaba yizendlalelo ezimbili esibumbeni, ingqimba yokuqala ifakwa ku-cone isikhunta esiphakeme esiphakeme, nge-ramming bar kusuka emaphethelweni ifakwe ngokulinganayo izikhathi eziyishumi nanhlanu, bese ilayishwa nge Ungqimba lwesibili lodaka, olufakwe cishe amasentimitha amabili aphezulu kunesikhunta esiyindilinga, i-cylindrical munye induku yokuqabulana nezikhathi eziyishumi nanhlanu. Lapho kulayishwa isihlabathi bese kufakwa phakathi, cindezela isigaxa se-trencate kufa ngesandla ukugwema ukunyakaza.

D. Ngemuva kokumatasa, thatha isembozo sokubumba, sebenzisa i-spatula ukuze unqamule udaka olungaphezulu kokubumba isiyingi isiyingi bese usula isicaba, bese uphakamisa ubumbano oluyindilinga lubheke phezulu. Shake izandla nge-crank yesondo ukwenza ithebula le-jumping ligxume amahlandla angamashumi amathathu ngesilinganiso esisodwa ngomzuzwana.

E. Ngemuva kokushaya, sebenzisa ama-calipers ukukala ububanzi be-wortar phansi, bese uthatha inani eliphakathi lamadayimitha amabili perpendicular komunye nomunye njengokufakwa kodaka lapho amanzi esetshenziswa, avezwa ku-mm. Lapho ireferensi yodumbu yenkomba ingukuphaza okungu-140 ± 5mm, ukusetshenziswa kwamanzi, ukusetshenziswa kwamanzi kungukusetshenziswa kwamanzi kwe-reference kasiti.

3.2.2 Ngokuya ngendlela engu-3.2.1, ukusetshenziswa kwamanzi kodaka nge-ejenti enciphisa amanzi kufinyelelwe ku-140 ± 5mm.

3.3. Izinga lokunciphisa lamanzi kodaka oluphathwe lubalwa ngale ndlela elandelayo:

Izinga lokunciphisa lamanzi ngodaka (%) = (w0-w1) / w0 × 100

Lapho, i-W0 - ukusetshenziswa kwamanzi (g) lapho ukuguquguquka kodaka lwezethenjwa kungu-140 ± 5mm;

I-W1 - Ukusetshenziswa kwamanzi (g) lapho ukuguquguquka kodaka nge-ejenti enciphisa amanzi kungu-140 ± 5mm.

Inani lamazinga okuncishiswa kwamanzi yi-arithmetic asho inani lamasampula amathathu.
