Mix proportion design method of regenerated backfill material
The invention relates to the technical field of use of regenerated backfill materials, and discloses a mix proportion design method of a regenerated backfill material, which specifically comprises the following steps: S1, determining the use position and requirement of the regenerated backfill material, and then determining the composition of the selected raw material; s2, determining a post-mixed raw material, and testing and determining the designed fluidity and the designed compressive strength of the mixed material after mixing is completed, so as to determine the primarily-selected water-solid ratio and the primarily-selected lime-sand ratio of the mixed raw material; and S3, determining the mix proportion of the regenerated backfill material, and observing and calculating whether the fluidity value reaches the standard or not. The purpose of the mix proportion design is as economical as possible on the premise of ensuring that the engineering properties meet the construction requirements, the evaluation of the engineering properties takes two indexes of working performance and compressive strength as design parameters, and the design strength is greater than the load stress borne by the regenerated backfill material, so that the mix proportion of the regenerated backfill material is achieved, and the engineering performance is improved. Therefore, the composite material has enough durability.
本发明涉及再生回填材料使用的技术领域，公开了再生回填材料的配合比设计方法，具体包括如下步骤：S1：确定再生回填材料使用位置和要求，再确定完成后选定原材料的组成成分；S2：确定后混合原材料，混合完成后对混合料进行设计流动度以及设计抗压强度的测试确定，从而确定混合原材料的初选水固比以及初选灰砂比；S3：确定再生回填材料的配合比，并且观察演算出流动度值是否达标。本发明配合比设计的目的是在保证其工程性质满足施工要求的前提下尽可能的经济，工程性质的评价以工作性能和抗压强度两大指标作为设计参数，设计强度要大于再生回填材料受到的荷载应力，从而达到再生回填材料的配合比，使其具备足够的耐久性。
