The invention discloses a powder admixture and concrete containing the powder admixture, wherein the powder admixture comprises the following components in parts by weight: 3.5-95 parts of incineration slag and 5-96.5 parts of an auxiliary material; the auxiliary material comprises the following components in parts by weight: 0-9.5 parts of aluminum oxide, 0-22 parts of silicon dioxide, 0-12 parts of ferric oxide, 0-35 parts of calcium oxide, 0-8 parts of carbon, 3-5 parts of a set retarder and 2-5 parts of an adhesive. According to the invention, the incineration slag and the auxiliary material are mixed to prepare the powder admixture to replace traditional mineral powder, so that the resource utilization of the incineration slag is enhanced, the production cost of the concrete is reduced, and the concrete prepared from the powder admixture has performance equivalent to that of concrete prepared from mineral powder.
本发明揭示了一种粉料掺合剂及含有粉料掺合剂的混凝土，其中，粉料掺合剂包括以下重量份的组分：焚烧炉渣3.5‑95份，配剂料5‑96.5份；配剂料包括以下重量份的组分：氧化铝0‑9.5份，二氧化硅0‑22份，三氧化二铁0‑12份，氧化钙0‑35份，碳0‑8份，缓凝剂3‑5份，粘合剂2‑5份。本申请采用焚烧炉渣和配剂料混合制成粉料掺合剂以替代传统的矿粉，加强了焚烧炉渣的资源化利用，降低了混凝土的生产成本，且采用粉料掺合剂制备出的混凝土具有与采用矿粉制备的混凝土相当的性能。
