摘要:
采用全计算法中水量计算公式和固定砂石体积法中粗骨料、砂子的固定体积分数相结合的方法,根据流动扩展度和L槽试验参数优选出强度等级为SCLC40和SCLC50的自密实轻骨料混凝土的配合比。分析了自密实轻骨料混凝土的抗压强度、劈裂抗拉强度、抗折强度、弹性模量等主要力学性能参数,并与普通混凝土的基本力学性能进行了对比。结果表明:自密实轻骨料混凝土具有强度高、韧性好、弹性模量小等特点,所得结论为自密实轻骨料混凝土的工程应用提供了参考。
Abstract:
Mix proportions for self-compacting lightweight concretes(SCLC)were chosen by formulas for the water content of overall calculation method and fixed volume content of aggregate method. On the basis of the parameters of flowing diameter and L-box, optimizing mix proportions for SCLC40 and SCLC50 were designed. The parameters of principal mechanical properties of SCLC, such as compression strength, cleavage extension strength, creasing resistance and elastic modulus were analyzed, and the basic mechanical properties of SCLC were compared with normal concrete. The results show that SCLC has higher strength, better tenacity and smaller elastic modulus and so on. The result provides a reference for the project application of SCLC.
