摘要
本文针对陶粒混凝土坍落度损失快、吸水大、难泵送的特点,通过预湿陶粒、提高入模坍落度、延长凝结时间、提高砂率、合理振捣和二次抹面等方法来满足泵遥及施工要求。
Ceramsity concrete features for fast slump, large water asorption, hard pumped. Though prewettng ceramsite, rmproving molding slump, extending setting time, enhancing sand proportion, vibrating rationally and secondary plastering, demanding standard of pumped concrete will the reached.
