Admixture for high-early-strength concrete and preparation method thereof
The invention relates to the technical field of high-early-strength concrete, in particular to an admixture for high-early-strength concrete and a preparation method of the admixture. The admixture is prepared from 600-700 parts of building waste powder, 6-10 parts of an early strength agent, 2-5 parts of a water reducing agent, 2-5 parts of an exciting agent, 150-200 parts of fly ash, 30-40 parts of silicon powder and 100-200 parts of Portland cement. The method has the advantages that the building waste powder is used as main aggregate, the early strength agent, the water reducer, the exciting agent and the like are added for filling, the activity of the building waste powder can be stimulated through carbonate, the building waste powder can reach enough strength, waste concrete, aerated blocks, bricks and other powder in the building waste powder can be rapidly hydrated and catalyzed, and the building waste powder can be recycled. Meanwhile, the triethanolamine early strength agent is matched with the polycarboxylate water reducer and the Portland cement, so that the waste building waste powder can be organically compounded, and after the waste building waste powder is mixed with water, calcium hydroxide is generated to form an effective activation effect on particles of the building waste powder, so that the filler formed by the building waste powder also has enough strength, and the use amount of the cement is reduced.
本发明涉及高早强混凝土技术领域，特别是一种高早强混凝土用掺合料及其制备方法，建筑废物粉料600‑700份、早强剂6‑10份、减水剂2‑5份、激发剂2‑5份、粉煤灰150‑200份、硅粉30‑40份、硅酸盐水泥100‑200份。本发明的优点在于：通过利用建筑废物粉料作为主要骨料，同时加入早强剂、减水剂、激发剂等填充，通过碳酸盐可以激发废弃建筑废物粉料的活性，使其达到足够的强度，使建筑废物粉料中的废混凝土、加气块以及砖块等粉料快速的水化催化，同时三乙醇胺早强剂配合聚羧酸盐减水剂加上硅酸盐水泥，可以有机复合废弃建筑废物粉料，在与水混合后，生成氢氧化钙对建筑废物粉料的颗粒形成有效的活化作用，使建筑废物粉料构成的填充料也具有足够的强度，减少了水泥用量。
