Experimental Study on Application Properties of Macroporous Ecological Concrete without Sand

摘要

This paper suggests that deposition paste area is one of those leading control indicators of mix proportion design for the macroporous ecological concrete without sand. By analyzing the effect of water-cement ratio, amount of cement, and type of coarse aggregates on application properties of concrete, it puts forward that when carrying out the mix proportion design of the concrete, setting the water-cement ratio as 0.4 can help the macroporous ecological concrete without sand acquire satisfying application properties. Based on this idea, experiments to the later period strengths and the erosion resistance property of concretes are tried out. Finally, the result of this series of experiments shows that the macroporous ecological concrete without sand possesses necessary conditions for plants to survive and grow up.
