Concrete glue reducing agent and preparation method thereof
The invention relates to the technical field of concrete preparation, and in particular, relates to a concrete glue reducing agent and a preparation method thereof. The glue reducing agent is composedof the preparation raw materials in parts by weight: 20-30 parts of substituted organic amine and 40-60 parts of water, wherein substituent groups of the substituted organic amine are selected from one or more of ester groups, sulfonic acid groups, carboxylic acid groups and hydroxyl groups. The invention provides the glue reducing agent. The glue reducing agent can be used in concrete, can obviously reduce the cement consumption, avoids the reduction of the concrete strength and slump, effectively reduces the time loss of the concrete, improves the harmony of the concrete, can act together with a water reducing agent and the like, saves the cost while ensuring the physical properties of the concrete, and conforms to JC/T2469-2018.
本发明涉及混凝土制备技术领域，更具体地，本发明涉及一种混凝土减胶剂及其制备方法。所述减胶剂的制备原料按重量份计，包括20～30份取代有机胺和40～60份水；所述取代有机胺的取代基选自酯基、磺酸基、羧酸基、羟基中的一种或多种。本发明提供了一种减胶剂，可用于混凝土中，可明显减少水泥用量的同时，避免混凝土强度和塌落度的下降，有效减少混凝土的经时损失，提高混凝土的和异性，可以和减水剂等共同作用，保证混凝土物理性质的同时节约成本，符合JC/T2469‑2018。
