粉煤灰综合利用 FLY ASH COMPREHENSIVE UTILIZATION 2015no.1 试验与应用 不同温度下锂渣混凝土的早期抗裂性能 Cracking Resistance at Early Ages of Concrete added with Lithium Slag under Different temperature 郭江华,侍克斌,吴福飞 (新疆农业大学水利与土木工程学院新疆乌鲁木齐830052) 摘要:针对新疆的特殊地理区域和矿渣资源,用刀口法对不同温度下锂渣混凝土早期抗裂进行了研究。试验结果 表明:锂渣掺量在一定范围内可以控制混凝土早期裂缝,且最优掺量为30%;高温时锂渣混凝土的耐久性优于素混凝土 的耐久性;锂渣水化产物的膨胀性能够补偿高性能混凝土的早期收缩,从而提高高性能混凝土的早期抗裂性能。 关键词:高性能混凝土锂渣不同温度;早期抗裂 中图分类号:TU528.2 文献码: 文章编号:1005-8249(2015)01-0033-03 Guo Jianghua ,Shi Kebin ,Wu Fufei Abstract :In view of the special geography and slag resources in Xinjiang ,the research on the early cracking resistance of lithium slag concrete under different temperature by using knife edge method .The experimental results show that :The of lithium slag concrete cracks can be controlled in a certain range ,and the optimal dosage is 30% :durability in high temperature lithium slag concrete durability is better than that of plain concrete .Expansion of early shrinkage of high performance conerete can pensate the lithium slag hydration products ,so as to improve the carly cracking resistance of high performance concrete . Key words :High performance concrete ,Lithium slag ,Different temperature ,the early...
