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.</em></p><p
