Khoom Description
PN-4 pob zeb nthuav dav tus neeg sawv cev yog U-hom nthuav tus neeg sawv cev, uas tuaj yeem hloov cov qauv sab hauv ntawm cov pob zeb, txhawm rau txhim kho qhov tawg tsis kam thiab impermebility ntawm pob zeb, thiaj li txo cov shirnkage thaum lub sij hawm ua vaj tse. Lub shirnkage compensating qhob tuaj yeem siv rau ntau lub caij tsim kho nrog kev ua haujlwm zoo, kev loj hlob ruaj khov ntawm lub zog mus ntev, tab sis tsis muaj corrosion rau steel tuav, uas tuaj yeem tiv thaiv alkali aggregate cov tshuaj tiv thaiv txhawm rau txhim kho lub zog ntawm cov pob zeb.

Tus nqi sib xyaw ntawm RN-4 feem ntau yog 8-10% raws li kev sib xyaw sab hauv (hloov cov khoom siv cementitious). Nws yog tsim rau ntau yam portland cements thiab tuaj yeem siv ua ke nrog lwm cov khoom sib xyaw, tab sis nws yuav tsum tau txiav txim siab tom qab tsim. Lub sij hawm sib xyaw ntawm RN-4 pob zeb yuav tsum tau txuas ntxiv los ntawm 30-60 vib nas this, nrog rau qhov kev ua yuam kev yog tsawg dua 0.5%. Tom qab 12-24 teev ntawm hardening rau RN-4 pob zeb, watering thiab curing yuav tsum tau nqa tawm tsis pub tsawg tshaj 14 hnub. Nws tsis raug tso cai siv rau hauv qhov chaw ua haujlwm nrog qhov kub ntawm ntau tshaj 80 degree. Yog tias qhov ntsuas kub ntawm kev tsim kho qis dua 5 degree, kev ntsuas rwb thaiv tsev yuav tsum tau ua.

Main Technical Performance:
Raws li qhov tshwj xeeb ntau npaum li cas, lub zog muaj zog thiab lub zog flexural yog 10-30% siab dua li qhov kev siv pob zeb ntawm 3 hnub, 7 hnub, thiab 28 hnub, thiab lub zog lig txuas ntxiv mus ntxiv. Tom qab koom nrog RN-4 composite expansion agent, impermeability Performance index ntawm pob zeb yog 1-2 npaug ntawm cov ntaub ntawv siv pob zeb. Tom qab qhov impermeability Performance index S ntau tshaj 30 yog muab tso rau hauv RN-4 composite expansion agent, cov pob zeb yuav muaj kev ua haujlwm zoo thiab poob qis me me.
