Chidule:
Ulusi wa Polyvinyl alcohol (PVA) watuluka ngati chowonjezera chowonjezera muukadaulo wa konkriti, zomwe zimathandizira kukonza zida zosiyanasiyana zamakina komanso kulimba. Ndemanga yonseyi imayang'ana zotsatira za kuphatikiza ulusi wa PVA mu zosakaniza za konkriti, kukambirana za katundu wawo, njira zopangira, ndi ntchito zosiyanasiyana pamakampani omanga. Kukambitsirana kumaphatikizapo zotsatira za ulusi wa PVA pa zinthu zatsopano ndi zowumitsidwa za konkire, ntchito yawo popewa ming'alu, ndi ubwino wa chilengedwe womwe ungakhalepo wokhudzana ndi kugwiritsidwa ntchito kwawo. Kuphatikiza apo, zovuta ndi ziyembekezo zamtsogolo zimawunikidwa kuti zitsogolere kafukufuku ndi chitukuko m'gawoli.
