Preparation method of phosphorus slag powder concrete
The invention discloses a preparation method of phosphorus slag powder concrete. The phosphorus slag powder concrete comprises,, by unit formula, 180-260 kg/m3 of cement, 20-40 kg/m3 of a spherical volcanic ash cementing material, 60-120 kg/m3 of phosphorus slag powder, 20-40 kg/m3 of a siliceous volcanic ash cementing material, 20-40 kg/m3 of limestone powder, 800-980 kg/m3 of machine-made sand,900-1000 kg/m3 of broken stone, 8-12 kg/m3 of a first additive, 0-1.5 kg/m3 of a second additive and 160-165 kg/m3 of water. A large amount of phosphorus slag powder is adopted to replace cement, thecement consumption is reduced, and environmental pollution is reduced; the setting time of the phosphorus slag powder concrete is controlled through the components of the admixture, and meanwhile, thelimestone powder is used for carrying out crystal nucleus induction on hydration of the phosphorus slag powder, so that the hydration reaction of the phosphorus slag powder is accelerated; the siliceous volcanic ash cementing material is doped to ensure the early strength of the concrete, and the spherical volcanic ash cementing material is utilized to improve the working performance of the concrete. The method overcomes the defects of delayed coagulation, low early strength and the like caused by low mixing amount and overhigh mixing amount of phosphorus slag powder, and has the significanceof large-scale popularization.
本发明公开了一种磷渣粉混凝土的制备方法，所述的磷渣粉混凝土包括单方用量kg/m3：水泥180‑260、球状火山灰质胶凝材料20‑40、磷渣粉60‑120、硅质火山灰胶凝材料20‑40、石灰石粉20‑40、机制砂800‑980、碎石900‑1000、1#外加剂8‑12、2#外加剂0‑1.5和水160‑165。本发明采用大量磷渣粉取代水泥，减少水泥用量，降低环境污染；通过外加剂的组份对磷渣粉混凝土的凝结时间进行控制，同时利用石灰石粉对磷渣粉的水化进行晶核诱导，加快了磷渣粉的水化反应；掺入硅质火山灰胶凝材料保证混凝土早期强度，利用球状火山灰质胶凝材料改善混凝土工作性能。本发明解决了磷渣粉掺量低、掺量过高出现缓凝、早期强度低等缺点，具有大范围推广的意义。
