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 .
