Early-strength water reducing agent for recycled aggregate concrete and preparation method thereof
The invention discloses an early-strength water reducing agent for recycled aggregate concrete and a preparation method thereof, and relates to the technical field of building materials, and every 100parts by weight of the early-strength water reducing agent for the recycled aggregate concrete comprises the following components in parts by weight: kettle bottom materials: 33-37.5 parts of water and 33-37.5 parts of polyether macromonomer; the liquid A is prepared from 3.1 to 3.4 parts of water, 3.1 to 3.4 parts of unsaturated carboxylic acid and 0.1 to 0.4 part of sodium methallyl sulfonate;liquid B: 0.04 to 0.07 part of vitamin C, 0.14 to 0.17 part of a chain transfer agent and 10 to 13 parts of water; a liquid C: 0.4 to 0.7 part of water and 0.13 to 0.16 part of an initiator; 0.3-0.6 part of caustic soda flakes, 0.3-0.45 part of a modifier and the balance of water. The early-strength water reducing agent for recycled aggregate concrete has the advantages that the setting time is shortened, the early strength is improved, the water-cement ratio is reduced, and the freeze-thaw resistance effect of concrete is improved.
本发明公开了一种再生骨料混凝土用早强减水剂及其制备方法，涉及建筑材料技术领域，再生骨料混凝土用早强减水剂，每100重量份早强减水剂包括以下重量份的组分：釜底料：水33‑37.5份、聚醚大单体33‑37.5份；A液：水3.1‑3.4份、不饱和羧酸3.1‑3.4份、甲基丙烯磺酸钠0.1‑0.4份；B液：维生素C 0.04‑0.07份、链转移剂0.14‑0.17份、水10‑13份；C液：水0.4‑0.7份、引发剂0.13‑0.16份；片碱0.3‑0.6份、0.3‑0.45份改性剂、余量为水。本发明的再生骨料混凝土用早强减水剂具有缩短凝结时间，增加早期强度，降低水灰比，增大混凝土的抗冻融效果的优点。
