Concrete, preparation method of concrete, precast pile and preparation method of precast pile
The invention discloses concrete, a preparation method of the concrete, a precast pile and a preparation method of the precast pile, the concrete comprises cement, a first aggregate, a second aggregate, a water reducing agent and water, the particle size of the first aggregate is greater than that of the second aggregate, and the concrete also comprises a composite mineral additive and cellulose ether. According to the concrete, by improving the components, the viscosity and the water-retaining property of cement paste can be improved, and when the concrete is used for preparing a precast pile, the bonding capacity of the cement paste is improved in the centrifugal process stage, so that the amount of residual paste generated in the precast pile preparation process is reduced, and the material cost is saved.
本发明公开了一种混凝土、混凝土的制备方法、预制桩及预制桩的制备方法，该混凝土包括成分：水泥、第一骨料、第二骨料、减水剂和水，所述第一骨料的粒径大于所述第二骨料的粒径，还包括成分：复合矿物外加剂和纤维素醚。该混凝土通过对组分进行改进，能够增加水泥浆的粘稠性和保水性，在由该混凝土制备预制桩时，在离心工艺阶段，提高了水泥浆的粘结能力，从而降低了预制桩制备过程中产生的余浆量，节省了材料成本。
