Concrete slurry modifier for reducing slurry permeability
The invention relates to the field of concrete admixtures, and particularly discloses a concrete slurry modifier capable of reducing slurry permeability. The concrete slurry modifier for reducing slurry permeability comprises 20-25 parts of acrylic acid; 6 to 10 parts of methyl allyl polyoxyethylene ether; 12 to 15 parts of butyose; 4 to 8 parts of malonyl urea; and 50 to 70 parts of deionized water. When the modifier is used, the diffusivity and permeability of concrete slurry can be effectively reduced, so that the permeation amount of the concrete slurry into slurry and the hole wall of a formed hole can be reduced, and the concrete filling coefficient of the rotary excavating cast-in-situ bored pile can be effectively reduced.
本申请涉及混凝土外加剂的领域，具体公开了一种降低浆体渗透性的混凝土浆料用改性剂。降低浆体渗透性的混凝土浆料用改性剂包括丙烯酸20‑25份；甲基烯丙基聚氧乙烯醚6‑10份；丁糖12‑15份；丙二酰脲4‑8份；去离子水50‑70份。本申请的改性剂在使用时能够有效降低混凝土浆料的扩散性和渗透性，从而能够减少混凝土浆料向泥浆以及成孔孔壁内的渗透的量，进而能够有效降低旋挖钻孔灌注桩的混凝土充盈系数。
