生态环境混凝土强度及干缩性能研究

<title>Research on the strength and dry shrinkage of eco environment concrete

选取适当配合比,制得28d抗压强度为24.94MPa的生态混凝土,研究表明,在相同配合比下,生态混凝土流动性稍差,强度稍低,干缩较大,但适当增加水泥用量,可使生态混凝土强度增大,提高混凝土中骨料最大粒径,可减少其收缩率.

<Abstrcat>Through choosing the proper mixed proportion,the eco?environment concrete that its compression strength reached to 24.9?Mpa in 28 day is made.The authors point out that the fliudness and strength of eco?environment concrete is worse than the clay brick aggregate concrete's to the same mixed proportion.By increasing the cement dosage properly,the eco?environment concrete would have little density and better strength.
