【摘要】：針對熱帶沙漠地區(qū)的典型氣候特點以及現(xiàn)場施工環(huán)境,利用溫濕度交變試驗箱,模擬施工現(xiàn)場的溫度和相對濕度環(huán)境條件,研究C30,C40和C50強度等級混凝土在不同溫度和不同濕度條件下的坍落度損失、凝結(jié)時間以及重塑時間的變化規(guī)律,為熱帶沙漠沿海氣候區(qū)大體積混凝土施工質(zhì)量控制提供參考依據(jù)。
[Abstract]:In view of the typical climatic characteristics of tropical desert area and site construction environment, the temperature and relative humidity environmental conditions of construction site are simulated by using the temperature and humidity alternating test box. The changes of slump loss, setting time and remolding time of C _ (30) C _ (40) and C _ (50) strength grade concrete under different conditions of temperature and humidity are studied, which provides a reference basis for the construction quality control of mass concrete in the coastal climate area of tropical desert.
