The invention relates to the technical field of concrete admixtures, in particular to a special admixture for recycled concrete. The special admixture is prepared from the following raw materials in parts by weight: 48-56 parts of a water reducing agent, 40-48 parts of a slump retaining agent, 6-8 parts of an anti-adsorbent, 3-4 parts of an early strength agent, 0.2-0.6 part of an expanding agent, 8-12 parts of a fly ash treatment substance, 0.1-0.3 part of a defoaming agent, 3-4 parts of a retarder and 4-6 parts of a structure enhancer. According to the admixture disclosed by the invention, the collapse loss of concrete can be reduced through scientific matching of all the components, the workability of the concrete is improved, and the flowability of the concrete is ensured.
本发明涉及混凝土外加剂技术领域，特别涉及再生混凝土专用外加剂；由下述重量份数的原料组成：减水剂48～56份、保坍剂40～48份、抗吸附剂6～8份、早强剂3～4份、膨胀剂0.2～0.6份、粉煤灰处理物8～12份、消泡剂0.1～0.3份、缓凝剂3～4份和结构强化剂4～6份。本发明的外加剂，通过各组分的科学搭配可以减少混凝土的坍塌度损失、提高混凝土的和易性，保证混凝土的流动性。
