Nanometer hydrated calcium silicate with adjustable setting time as well as preparation method and application of nanometer hydrated calcium silicate
The invention provides nano calcium silicate hydrate with adjustable setting time as well as a preparation method and application thereof, and the nano calcium silicate hydrate comprises the following components in parts by weight: 10-40 parts of a calcium source, 0.5-3 parts of a zinc source, 10-30 parts of a silicon source, 5-15 parts of a polycarboxylic acid water reducer, 0.5-2 parts of a stabilizer and 100-400 parts of water. According to the nano calcium silicate hydrate capable of adjusting the setting time, zinc ions are introduced into a system, the setting time of concrete can be adjusted in order according to actual engineering requirements by adjusting the zinc-silicon ratio, higher adaptability is shown, the early strength of a cement-based material can be improved, and the setting time of the concrete can be adjusted according to the actual engineering requirements. The setting time of the concrete is regulated and controlled, and different engineering requirements are met. The product is high in stability, easy to store, suitable for various cement-based materials, easy in raw material obtaining, simple in production process, capable of remarkably reducing the production cost, suitable for large-scale popularization and industrial production, remarkable in environmental benefit and economic value, and has positive significance in promoting sustainable development of the building industry.
本发明提供一种可调凝结时间的纳米水化硅酸钙及其制备方法和应用，以重量分数计，包括以下组分：钙源10‑40份、锌源0.5‑3份、硅源10‑30份、聚羧酸系减水剂5‑15份、稳定剂0.5‑2份、水100‑400份。该可调凝结时间的纳米水化硅酸钙，在体系中引入锌离子，通过调节锌硅比，可以根据工程实际需要，有序调节混凝土的凝结时间，表现出更强的适应性，不仅能提高水泥基材料的早期强度，而且能够根据实际工程需要，对混凝土的凝结时间进行调控，满足不同工程需求。产品稳定性高，易保存，适用于各类水泥基材料，且原材料易得，生产工艺简单，能够显著降低生产成本，适合大规模推广和工业化生产，表现出显著的环境效益和经济价值，对推动建筑行业的可持续发展有积极意义。
