Super-retarding concrete and preparation method thereof
The invention relates to the field of concrete, in particular to super-retarding concrete and a preparation method thereof. The invention relates to super retarded concrete, which is prepared from the following raw materials in parts by mass: 280 to 300 parts of cement, 160 to 175 parts of water, 1000 to 1200 parts of coarse aggregate, 700 to 900 parts of fine aggregate, 1 to 4 parts of welan gum, 0.8 to 2.5 parts of ethylenediamine tetramethylenephosphonic acid, 5 to 15 parts of coco coir and 80 to 120 parts of admixture, the preparation method comprises the following steps: mixing welan gum, ethylenediamine tetramethylenephosphonic acid, coco coir and 10-20% of water to obtain a premixed solution; uniformly mixing the cement, the residual water and the admixture; continuing to add the premixed liquid, and uniformly mixing; and continuously adding the coarse aggregate and the fine aggregate, and uniformly mixing to obtain a finished product. The concrete has the advantage of delaying the setting time of the concrete.
本申请涉及混凝土领域，更具体地说，它涉及一种超缓凝混凝土及其制备方法。一种超缓凝混凝土，按照质量份数，包括以下原料：280‑300份水泥、160‑175份水、1000‑1200份粗骨料、700‑900份细骨料、1‑4份温轮胶、0.8‑2.5份乙二胺四亚甲基膦酸、5‑15份椰糠、80‑120份掺合料；其制备方法为：将温轮胶、乙二胺四亚甲基膦酸、椰糠与10‑20%的水混合，得到预混液；将水泥、剩余水、掺合料混合至均匀；再继续加入预混液混合至均匀；再继续加入粗骨料、细骨料混合至均匀，得到成品。本申请具有延缓混凝土的凝结时间的优点。
