Viongezeo vya Zege nyepesi | Mawakala wa Utendaji wa Juu wa Kutoa Mapovu kwa Saruji ya Simu
Matumizi ya maji kupita kiasi yanaweza kusababisha matatizo ya ubora wa Saruji Nyepesi. Kwa hakika itakuwa na athari kubwa kwenye soko la Saruji Nyepesi.Je, ni matatizo gani kuu katika ujenzi wa Saruji Nyepesi?
Matumizi mengi ya maji ya Saruji Nyepesi husababisha kupungua kwa ubora wa jumla wa Saruji Nyepesi. Inajulikana kuwa mchanganyiko wa uwiano wa saruji ya maji-saruji ni kiashiria muhimu cha kiufundi. Wakati kiasi cha maji kinazidi kiasi cha maji kutumika kwa ajili ya hydration ya saruji, kiasi kikubwa cha maji, chini ya nguvu ya saruji. Wakati matumizi ya maji ni makubwa sana, itasababisha kasoro kama vile kulegalega na nyufa za saruji. Kwa hiyo, in the process of mixing concrete, the water consumption should be controlled as much as possible, and if necessary, the method of adding a water reducing agent should be used to ensure the quality of the concrete. Lightweight Concrete is a type of concrete that also requires control of water usage. In actual construction, the water consumption of Lightweight Concrete can not be effectively controlled. Once the water consumption exceeds a certain range, the cement will produce obvious precipitation and segregation. The Lightweight Concrete has uneven density on the upper and lower sides, low surface strength, and a layer of cement slurry on the bottom layer. Aidha, too much moisture will slowly evaporate during the solidification process of the cement, and the void left after evaporation is a gap that is connected without closing, which is extremely unfavorable for the heat preservation effect. Kwa hiyo, excessive water consumption is extremely harmful to Lightweight Concrete. Some construction companies can’t recognize this point. In order to increase their liquidity and facilitate construction, the water-cement ratio is very large, and it is also known as “self-leveling”. This makes it difficult to meet the requirements of important physical properties such as thermal conductivity, density and compressive strength of Lightweight Concrete.
Strictly control the water-cement ratio, and change the “self-leveling” into a combination of “self-flow” na “scratch”. Kudhibiti uwiano wa saruji ya maji ya Saruji Nyepesi ni mojawapo ya hatua muhimu za kuhakikisha ubora wa ujenzi. Katika baadhi ya miji ya China, kumekuwa na uzoefu wa mafanikio katika kutumia Saruji Nyepesi kama insulation ya paa. Kufanya paa, Saruji nyepesi lazima iwe na msimamo fulani ili kutatua hitaji la kupata mteremko.
Mazoezi yamethibitisha kuwa baada ya uwiano wa saruji ya maji kupunguzwa, uthabiti umepanda, ambayo inaweza kukidhi mahitaji ya mteremko kwenye muundo na kuhakikisha ubora wa Saruji nyepesi. Seli ni sare, mnene na huru. Bila shaka, kufanya safu ya insulation ya sakafu inapokanzwa, hauitaji kuwa nene kama paa. Kwa urahisi wa ujenzi, uthabiti unaweza kuwa chini ipasavyo. Udhibiti wa uwiano wa saruji ya maji sio thamani maalum. Inapaswa kurekebishwa kulingana na ukame na unyevu wa ardhi, joto na unyevunyevu. Kwa kawaida, uwiano wa saruji ya maji kwa ujumla hudhibitiwa karibu 0.55. Uwiano kama huo wa saruji ya maji, uthabiti wa Saruji Nyepesi inaweza kuwa kubwa zaidi, ni vigumu kufikia “self-leveling”, lakini pamoja na “scratch gorofa” kwa kusawazisha, inaweza kukidhi kabisa mahitaji ya kujaa. Kwa kudhibiti matumizi ya maji kwa njia inayofaa na kwa ufanisi, ubora wa jumla wa Saruji Nyepesi unaweza kuboreshwa kwa kiasi kikubwa.Nyingine zaidi ya hii,Wakala wa kupunguza maji unaweza kutumika katika mchakato huu.Wakala wa kupunguza maji unaweza kukusaidia kutatua tatizo hili vizuri sana.
