| Abstract: | Laboratory experiments on the moderate-heat, low-heat Portland cement and fly ash concrete are carried out with the same water-cement ratio. Results show that the long-term strength of the low-heat cement concrete is higher than that of the moderate-heat cement concrete, and the resistance ability against abrasion and cracking of low-heat cement concrete is also better than that of the moderate-heat cement concrete. Observations on the stilling guide wall of Xiangjia- ba project show that temperatures of the low-heat cement concrete are 6.5 - 7.1 ℃ lower than that of the moderate-heat cement concrete, and no cracks are found in the low-heat cement concrete. |
