Concrete composition containing steel fibers
The invention discloses a concrete composition containing steel fibers, and relates to the technical field of building materials. The concrete composition is prepared from the following raw materials in parts by weight: 120 to 140 parts of cement, 80 to 100 parts of water, 50 to 80 parts of steel fiber, 20 to 30 parts of fly ash, 6 to 10 parts of a modifier, 6 to 8 parts of a melamine water reducing agent and 1 to 5 parts of a dispersing agent. The modifier comprises sorbitan monopalmitate, calcium stearate and sodium fluosilicate in a mass ratio of 7:3:2. The preparation method comprises the following steps: (1) preparing cement, water, steel fibers, fly ash, a modifier, a melamine water reducing agent and a dispersing agent; (2) transferring the raw materials in the step (1) into a stirrer, conducting stirring and mixing, and pouring the formed mixture into a mold; and (3) curing the concrete in the mold in the step (2). Compared with the prior art, the prepared concrete is excellent in various performance parameters and has high strength and high heat storage and heat preservation effects.
本发明公开了一种含钢纤维的混凝土组合物，涉及建筑材料技术领域。其中混凝土组合物，以重量份计，包括以下原料：水泥：120份‑140份，水：80份‑100份，钢纤维：50份‑80份，粉煤灰：20份‑30份，改性剂：6份‑10份，三聚氰胺减水剂：6份‑8份，分散剂：1份‑5份；其中改性剂包括山梨醇酐单棕榈酸酯、硬脂酸钙及氟硅酸钠，上述三者之间的质量比为7：3：2；其制备方法如下：(1)准备水泥、水、钢纤维、粉煤灰、改性剂、三聚氰胺减水剂、分散剂；(2)步骤(1)中各原料转移到搅拌机中进行搅拌混合，并倒入模具中；(3)对步骤(2)模具中的混凝土进行养护。与现有技术相比，制备的混凝土的各项性能参数优异，具有高强度及高蓄热保温的效果。
