Novel steel slag self-compacting concrete mix proportion design method
The invention discloses a method for designing a mix proportion of steel slag self-compacting concrete based on target shaping per viscosity and compressive strength of required concrete. The method is characterized in that steel slag is used as coarse aggregate, material cost is saved, a design drawing is provided as a mix proportion design guide, and simplicity and practicability of the method are improved. The target plastic viscosity of the mixture ranges from 3 Pa s to 15 Pa s, and the characteristic cube strength of the mixture at the age of 28 days ranges from 30 MPa to 80 MPa. According to the novel steel slag self-compacting concrete mix proportion design method, after the target plastic viscosity is determined, the ratio of the water content to the cementing material is calculated, then the content, the water content and the solid phase components of the cementing material are solved according to a design drawing curve, the actual concrete plastic viscosity is calculated andcompared with the target plastic viscosity, and therefore the requirement for the target plastic viscosity is met. And the stable performance of the concrete is ensured, and the reasonable steel slagself-compacting concrete mix proportion is achieved through the method.
本发明公开了一种基于所需混凝土目标塑形每粘度和抗压强度的钢渣自密实混凝土配合比的设计方法。其特点在于使用钢渣作为粗骨料，节省材料成本，提供设计图作为配合比设计指南而增加了其简单性和实用性。其中混合物的目标塑性粘度在3‑15Pa s之间，28天龄期的特征立方体强度在30‑80MPa之间。本发明的新型钢渣自密实混凝土配合比设计方法，确定目标塑性粘度后计算含水量与胶凝材料比率，而后根据设计图曲线求出胶凝材料含量、含水量、固相成分，计算出实际混凝土塑性粘度，与目标塑性粘度比较，以满足目标塑性粘度要求。保证混凝土的性能稳定，通过此方法达到合理的钢渣自密实混凝土配合比。
