Preparation method of early-strength anti-freezing recycled concrete
The invention provides a preparation method of early-strength anti-freezing recycled concrete, which comprises the following preparation steps: taking materials according to a ratio, mutually doping a cementing material and aggregate for multiple times, and uniformly stirring and mixing to obtain a mixed material I; blending the composite early-strength anti-freezing component with the reinforced fiber, uniformly mixing, and drying at low temperature to obtain a mixed material II; equally dividing the mixing water into two parts according to the mass ratio of the mixed material I to the mixed material II; blending the mixing water equivalent to the mixed material I with the mixed material I, and uniformly stirring to obtain a mixed material III; alternately adding the mixed material II and the residual mixing water into the mixed material III under a stirring condition, and continuously stirring for 45-120 seconds after the addition is completed, so as to obtain concrete slurry; and the concrete slurry is constructed, spread, cured and formed, and the concrete is obtained. The raw material selection and matching are reasonably optimized, the preparation method is specifically adjusted, the prepared slurry is uniform and high in quality, the formed product is stable in structure and high in strength and freezing resistance, and the comprehensive performance is remarkably improved.
本发明提出了一种早强型抗冻再生混凝土的制备方法，包括以下制备步骤：按配比取料，将胶凝材料与骨料分多次互掺，搅拌混均得混合物料一；将复合早强抗冻组分与强化纤维共混，混匀后，低温干燥，得混合物料二；将拌合水按混合物料一、混合物料二的质量比等比分成两份；将与混合物料一相当的那份拌合水与混合物料一共混，搅拌均匀后，得到混合物料三；在搅拌条件下将混合物料二和剩余的拌合水交替加入混合物料三中，添加完成后持续搅拌45‑120s，即得混凝土浆料；将混凝土浆料施工摊平，养护成型，即得；本申请合理优化原料选配并针对性调整制备方法，配制的浆料均匀高质，成型产品结构稳定，高强抗冻，综合性能显著提高。
