混凝土溫控問題的本質(zhì)在于混凝土是熱的不良導(dǎo)體

1、混凝土溫控問題的本質(zhì)在于混凝土是熱的不良導(dǎo)體?，F(xiàn)場一般來說控制入倉溫度實(shí)施情況不夠普遍，以通水冷卻為主。水冷和風(fēng)冷骨料作為控制入倉溫度的措施，效果有限，同時(shí)控制水泥儲罐的溫度也非常重要。 一般來說冬季平均氣溫在零度以上的地區(qū)，在沒有寒潮到來的情況下，表面保護(hù)可以要求不 那么嚴(yán)格；但是在北方高緯度地區(qū)和藏區(qū)表面保護(hù)需要及時(shí)跟上，有些情況下需運(yùn)行多年后 才進(jìn)行拆除。通水冷卻一般要求在混凝土初凝后進(jìn)行，關(guān)于在初凝前還是初凝后通水較好，現(xiàn)在仍有爭議。 個人意見覺得應(yīng)該比對彈模和強(qiáng)度曲線，把其中之一終值按照比例縮放為和另一終值相同。 選擇曲線彈模小于強(qiáng)度的時(shí)刻進(jìn)行通水較為合適?；炷粮煽s影響范圍主要限于

2、表面，按照規(guī)范可將混凝土的干縮影響折算為10-15度的溫降， 所以做好混凝土養(yǎng)護(hù)比較重要。12.28811E-0510655.5611691.99923.38598E-0512690.8117301.96633.90717E-0513990.6719965.22644.197E-0514957.2421446.19154.37885E-0515729.6622375.44464.50289E-0516373.8623009.26774.59266E-0516926.6423468.01384.66056E-0517410.7323814.94194.71366E-0517841.2424086
