Cov teeb meem tshwm sim ntau ntawm kev ua npuas dej yog cov ntxhib deg, ciav, tawg, sab hauv hollowing, qhov qhib, plam zuag qhia tag nrho los yog siab zog sib zog sib txawv, thiab tsis tshua muaj compressive zog. Thawj qhov laj thawj rau qhov ntxhib, qhov qhib, xoob tag nrho los yog siab compressive zog thiab tsawg compressive zog yog qhov zoo ntawm foamed qhob foaming tus neeg sawv cev. Qhov thib ob yog qhov teeb meem ntawm lub tshuab foaming. Qhov yooj yim vim li cas rau kev tawg yog tias lub shrinkage ntawm foamed qhob slurry yog ntau loj tshaj uas ntawm lub hauv paus khoom. Secondly, cov pob zeb ua rau nws tus kheej tsis yog sib npaug thiab nws cov tensile lub zog tsis dhau tsawg heev.Tus npuas los ua cov khoom siv qib siab tsim tau los ntawm Sha Mu tshiab khoom lag luam yog tsim rau kev kho foam npuas, thiab tau zoo ua ke nrog cov khoom polyurea, txo cov teeb meem ntawm cracking thiab bulging nyob rau hauv foam qhob kev tsim kho.
