Concrete doped with white mud and white mud doping method
The invention discloses concrete doped with white mud. The concrete is prepared from the following components in parts by weight: 350 parts of cement, 170 parts of water, 650 parts of sand, 1100 parts of gravel and 0.7 part of a water reducing agent, the invention discloses a method for doping white mud into concrete, the white mud comprises 10-80 parts of the white mud, the addition amount of the white mud is selected according to an application scene, and the method for doping the white mud into the concrete comprises the following steps: step 1, obtaining a fitting formula of the white mud with different doping amounts and the age and the compressive strength of the concrete, obtaining all measured data, and obtaining a fitting formula fc = 8.2342 lt-0. 348 u + 21.845 of the white mud with different contents and the age strength; 2, determining the mixing amount of the white mud according to application requirements, and reversely calculating to obtain the mixing amount of the white mud; for a common non-bearing component, according to the specified strength of the common non-bearing component, under the condition that the white mud is recycled as much as possible, the effect of recycling the white mud can be achieved through the curing period; for a load-bearing component, a relatively balanced white mud parameter can be found, and the load-bearing component can reach the strength required by load bearing through a standard curing age.
本发明公开了一种掺入白泥的混凝土，包括如下组份重量份：水泥350份、水170份、砂料650份、碎石1100份和减水剂0.7份；所述白泥为10~80份，并根据应用场景选择白泥添加量，所述混凝土中白泥掺入方法如下：第一步，获取不同掺量的白泥与龄期与混凝土的抗压强度的拟合公式，获取所有测定数据，得出不同含量的白泥与龄期强度拟合公式：fc=8.2342lnt‑0.348u+21.845；第二步，根据应用需求确定白泥掺量，反向计算得到白泥掺量；本发明对于普通非承重构件，可根据其规定强度，在尽量多回收白泥的情况下，可通过养护龄期来使其达到回收白泥的作用；对于承重构件，可寻求较为平衡的白泥参量，通过标准养护龄期使其达到承重所需强度。
