Super early strength concrete
A super early strength concrete is characterized by comprising the following components: ordinary Portland cement, an accelerator, silicon powder, an efficient water reducer, sand and stone. The superearly strength concrete should have good fluidity and construction operability, and can reach the strength capable of bearing traffic load in a very short time after construction, and the later strength is not influenced by the early strength performance. The concrete is prepared from the following components in parts by weight: 510 to 531 parts of cement, 46 to 44 parts of silicon powder, 515 to535 parts of sand, 1145 to 1191 parts of stone, 6.7 to 6.9 parts of an efficient water reducer, 14.0 to 14.2 parts of an accelerator and 167 to 173 parts of water. The super early strength concrete has the advantages that the super early strength concrete is developed by using conventional raw materials and a universal process method, and the raw materials are not specially required. The principle of material selection is that cement sources are sufficient, aggregate distribution is wide and rich, and application and popularization are facilitated. After construction, the concrete can reach the strength capable of bearing traffic load in a short time, and the later strength is not influenced by the early strength performance.
一种超早强混凝土，其特征是：组分由普通硅酸盐水泥，速凝剂、硅粉、高效减水剂、砂、石组成。超早强混凝土的关键为要具有良好的流动性与施工操作性和施工后材料应在很短的时间内达到可以承受交通荷载可以承受的强度，并且后期强度不受早强性能的影响。各组分的重量份为：水泥510～531份，硅粉46～44、砂515～535份、石1145～1191份、高效减水剂6.7～6.9份、速凝剂14.0～14.2、水167～173份。其优点是：用常规的原材料及通用的工艺方法研制超早强混凝土，对原材料不作特殊的要求。选料的原则是水泥货源较充足、骨料分布广并且丰富，以便于推广应用。施工后材料可以在很短的时间内达到可以承受交通荷载可以承受的强度，并且后期强度不受早强性能的影响。
