3D printing vegetation concrete material, mortar, component and preparation method
The invention provides a 3D printing vegetation concrete material, mortar, a component and a preparation method, and relates to the field of vegetation concrete. The 3D printing vegetation concrete material is prepared from the following components in parts by weight: 100 parts of a high-solid-waste low-alkali cementing material, 60 to 70 parts of sand grains, 10 to 35 parts of spherical pottery sand, 0.10 to 0.30 part of a retarder, 0.02 to 0.04 part of a hardening accelerator, 0.03 to 0.05 part of a water-retaining agent, 0.30 to 0.60 part of a thixotropic lubricant and 35 to 45 parts of water. According to the 3D printing vegetation concrete material, ordinary Portland cement is replaced with the high-solid-waste low-alkali cementing material, and the low-pH-value sulphoaluminate cement clinker and the fluorgypsum are adopted, so that the alkalinity of a system can be effectively reduced, and the strength of a concrete member can be ensured. The concrete material has the properties of flowability, extrudability, constructability, cracking resistance, large porosity and low alkalinity, and meets the requirements of plant-growing concrete and 3D printing concrete.
本发明提供了一种3D打印植生混凝土材料、砂浆、构件及制备方法，涉及植生混凝土领域。该3D打印植生混凝土材料，以重量份计，包括：高固废低碱胶凝材料100份、砂粒60～70份、球形陶砂10～35份、缓凝剂0.10～0.30份、促硬剂0.02～0.04份、保水剂0.03～0.05份、触变润滑剂0.30～0.60份、水35～45份。上述的3D打印植生混凝土材料中，采用高固废低碱胶凝材料替代普通硅酸盐水泥，采用低pH值的硫铝水泥熟料和氟石膏，既能有效降低体系碱度，且能确保混凝土构件强度。上述混凝土材料兼具流动性、挤出性、建造性、抗开裂性能、大孔隙率和低碱度的性能，符合植生混凝土和3D打印混凝土的需求。
