Special composite early-strength water reducing agent for pipe pile and use method of special composite early-strength water reducing agent
The invention relates to a special composite early-strength water reducing agent for a pipe pile and a use method of the special composite early-strength water reducing agent. The special composite early-strength water reducing agent for the pipe pile comprises the following components: 25-55 parts of a high-performance polycarboxylic acid water reducing agent; 4.5 to 10.5 parts of an early strength agent; 3 to 20 parts of a retarder; 1.5-5 parts of a sulfonating agent; wherein the early strength agent comprises triethanolamine, montmorillonite modified by quaternary ammonium salt and diatomite; the mass of the early strength agent is 18%-25% of the mass of the high-performance polycarboxylate superplasticizer; the mass of the retarder is 8%-14% of the mass of the high-performance polycarboxylic acid water reducing agent. According to the scheme provided by the invention, the concrete can have good fluidity and plasticity while the hydration reaction of cement is accelerated, and the early strength and construction performance of the concrete are improved, so that the tubular pile is easy to cast and form in the production process, the stability and durability of the concrete are improved, and good slump retaining performance is achieved.
本申请涉及一种管桩专用复合型早强减水剂及其使用方法。该管桩专用复合型早强减水剂，包括：高性能聚羧酸减水剂25‑55份；早强剂4.5‑10.5份；缓凝剂3‑20份；磺化剂1.5‑5份；其中，所述早强剂包括三乙醇胺以及经过季铵盐改性的蒙脱石和硅藻土；所述早强剂是所述高性能聚羧酸减水剂质量的18％～25％；所述缓凝剂是所述高性能聚羧酸减水剂质量的8％～14％。本申请提供的方案，能够在加速水泥的水化反应的时候使混凝土具有良好的流动性和可塑性，提高混凝土的早期强度和施工性能，从而使管桩生产过程中易于浇筑成型，并提高混凝土的稳定性和耐久性，达到良好的保坍性能。
