Slate aggregate concrete
The embodiment of the invention relates to the technical field of alkali-resistant aggregate reaction, in particular to slate aggregate concrete which comprises at least four of phosphorus slag powder, coal ash, an FA functional additive, a graphene reinforcing agent and polyvinyl alcohol in parts by weight, and further comprises water, cement, slate fine aggregate and slate coarse aggregate. Wherein the slate concrete is prepared from 160 to 171 parts of water, 266 to 308 parts of cement, 950 to 1080 parts of slate fine aggregate, 750 to 900 parts of slate coarse aggregate, 38 to 114 parts of phosphorus slag powder, 38 to 76 parts of fly ash, 0 to 3.8 parts of FA functional additive, 0 to 0.38 part of graphene reinforcing agent and 0 to 3.8 parts of polyvinyl alcohol. Through the mode, the slate aggregate concrete provided by the invention has the advantages that the production cost can be reduced, and meanwhile, the risk of alkali-aggregate reaction of the slate aggregate concrete is reduced, so that the service life of the slate aggregate concrete is prolonged.
本发明实施例涉及抗碱集料反应技术领域，具体涉及一种板岩集料混凝土，以重量份数计，板岩集料混凝土包括磷渣粉、粉煤灰、FA功能型添加剂、石墨烯增强剂和聚乙烯醇中的至少四者，还包括水、水泥、板岩细集料和板岩粗集料；其中，水160～171份、水泥266～308份、板岩细集料950～1080份、板岩粗集料750～900份、磷渣粉38～114份、粉煤灰38～76份、FA功能型添加剂0～3.8份、石墨烯增强剂0～0.38份和聚乙烯醇0～3.8份。通过上述方式，本发明实提供的板岩集料混凝土可减少生产成本，同时降低板岩集料混凝土发生碱集料反应的风险，从而延长板岩集料混凝土的使用寿命。
