Cement seepage-proofing agent and application thereof in concrete
The invention provides a cement seepage-proofing agent and application thereof in concrete, and particularly relates to the technical field of concrete additives. The cement seepage-proofing agent is mainly obtained by reacting bentonite, an anionic polymer, an initiator and a cross-linking agent, the preparation method comprises the following steps: adding an aqueous solution of an anionic polymer into bentonite, then adding an initiator and a cross-linking agent, and uniformly mixing to obtain a mixture; and continuously extruding, standing and drying to obtain the cement seepage-proofing agent. The invention provides the anti-seepage agent with better performance for the field of concrete. After the cement anti-seepage agent is added, the permeability coefficient of concrete is reduced from 10 <-5 > to 10 <-8 >, and the compactness of the concrete is greatly improved; in addition, the tolerance of the concrete to high-salt pollutants is also improved; the concrete curing time is shortened from 28 days to 7 days, the project progress is accelerated, the total project cost is reduced, and water resources are saved. According to the cement seepage-proofing agent, the quality of concrete is improved, the application field of the concrete is expanded, and the development of downstream industries is promoted.
本发明提供了一种水泥防渗剂及其在混凝土中的应用，具体涉及混凝土添加剂技术领域。该水泥防渗剂主要由膨润土、阴离子聚合物、引发剂和交联剂反应得到；将阴离子聚合物的水溶液加到膨润土中，然后加入引发剂和交联剂混合均匀得到混合物；继续挤压、静置、烘干得到水泥防渗剂。本发明为混凝土领域提供了性能更好的防渗剂。添加该水泥防渗剂后，混凝土的渗透系数从10‑5降低至10‑8，大幅提高了混凝土的密实程度；另外混凝土对高盐污染物的耐受性也得到了提升；混凝土的养护时间从28天缩短至7天，加快了工程进度，降低了工程总成本，节约了水资源。本发明的水泥防渗剂提高了混凝土的质量，扩大了混凝土的应用领域，促进了下游产业的发展。
