Development of Composite Antifreeze to Ecological Slope Protection Substrate

Referring to the antifreeze improved test of cement-soil and combining with its own characteristics and functions of the ecological slope protection material, the paper selects palm fiber, silicon powder and surface active agent as the antifreeze raw materials to the ecological slope protection substrate. Based on the method of antifreeze on concrete, through the evaluation of relative dynamic elastic modulus and mass loss rates in the process of freeze-thaw cycles, the results show that the best composite antifreeze to improve the frost resistance property of the ecological slope protection substrate is that palm fiber: silicon powder: surface active agent=1: 3: 0.05. While the additive amount reaches 1.5% by weight of the dry ecological slope protection substrate, the best effect will be obtained.
