The invention discloses an alkali reducing agent for ecological slope protection concrete. The alkali reducing agent is prepared from the following raw materials in parts by weight: 5-20 parts of superfine silicon dioxide, 10-50 parts of silica fume, 20-70 parts of coal ash, 2-10 parts of a water reducing agent, 1-8 parts of monopotassium phosphate, 1-8 parts of ammonium dihydrogen phosphate, 1-8parts of ammonium bicarbonate and 1-8 parts of ferrous sulfate. The alkali reducing agent disclosed by the invention is suitable for vegetation type ecological slope protection concrete slope protection; the alkalinity of the pervious concrete can be effectively reduced; the pH value of the pervious concrete is reduced from 12-13 to 8-9; the pH value condition of plant growth is met, effective nutrient elements are provided for plant growth while alkali is reduced through the alkali reducing agent, plants can grow better, an excellent living environment is provided for plant growth, and the natural impression of the plant-growing type ecological slope protection concrete revetment is facilitated; the technical problems that an existing alkali reducing agent is poor in alkali reducing effect in the plant-growing concrete, and plant growth is not facilitated are solved.
本发明公开了一种用于生态护坡混凝土的降碱剂，由以下重量份原料组成：超细二氧化硅5～20份、硅灰10～50份、粉煤灰20～70份、减水剂2～10份、磷酸二氢钾1～8份、磷酸二氢铵1～8份、碳酸氢铵1～8份、硫酸亚铁1～8份。本发明降碱剂适用于植生型生态护坡混凝土护坡，不仅能够有效的降低透水混凝土碱性，使透水混凝土的PH值从12～13降到低到8～9，满足了植物生长的PH值条件，而且降碱剂在降碱的同时还为植物生长提供有效的营养元素，使植物更好的生长，为植物生长提供了优良的生存环境，有利于植生型生态护坡混凝土护坡的自然观感；还解决了现有降碱剂在植生混凝土中降碱效果差、不利于植物生长的技术问题。
