The invention relates to the technical field of building materials, in particular to super-retarding concrete. The formula comprises the following raw materials in parts by weight: 210-250 parts of cement, 30-50 parts of an admixture, 3-5 parts of basalt fiber, 8-10 parts of an additive, 805-810 parts of river sand, 985-1010 parts of stone and 165-170 parts of water. The additive comprises a waterreducing agent, a retarder, a water retaining agent and a defoaming agent, the weight ratio of the water reducing agent to the retarder to the water retaining agent to the defoaming agent is (6-8): (7-9): (3-5): (1-2), the admixture comprises phosphorus slag, coal ash and microbeads, and the weight ratio of the phosphorus slag to the coal ash to the hollow glass microbeads is (10-20) :(40-50) :(10-15). The super-retarding concrete with higher strength and longer setting time is obtained by reasonably proportioning the cement, the admixture, the basalt fibers, the additive, the river sand, thestone and the water and matching the raw materials, pumping construction can be carried out, segregation and layering are not likely to happen, and the super-retarding concrete has important significance on development of the concrete industry.
本发明涉及建筑材料技术领域，具体涉及一种超缓凝混凝土；包括以下重量份数的原料：水泥210‑250份、掺合料30‑50份、玄武岩纤维3‑5份、外加剂8‑10份、河砂805‑810份、石子985‑1010份和水165‑170份，所述外加剂由减水剂、缓凝剂、保水剂和消泡剂组成，所述减水剂、缓凝剂、保水剂和消泡剂的重量比为(6‑8)：(7‑9)：(3‑5)：(1‑2)，所述掺合料由磷矿渣、粉煤灰和微珠组成，所述磷矿渣、粉煤灰和空心玻璃微珠的重量比为(10‑20)：(40‑50)：(10‑15)。本发明通过水泥、掺合料、玄武岩纤维、外加剂、河砂、石子和水进行合理配比，各原料之间相互配合所得到具有更高强度和更长凝结时间的超缓凝混凝土，且可进行泵送施工，而且不易产生离析、分层，对混凝土工业的发展具有重要意义。
