Manufacturing process of hybrid fiber regenerated roller compacted concrete with high elastic modulus and low elastic modulus
The invention discloses a manufacturing process of hybrid fiber regenerated roller compacted concrete with high and low elastic modulus. The manufacturing process comprises the following steps: step 1, uniformly mixing cement, low-elastic modulus fibers, high-elastic modulus fibers, a high-efficiency water reducing agent and fly ash; step 2, adding water for concrete mixing into the mixture in the step 1, and stirring to prepare cement slurry; step 3, adding sand into the cement slurry in the step 2, and uniformly mixing to prepare cement mortar slurry; and 4, adding the rolled recycled coarse aggregate into the cement mortar slurry obtained in the step 3, and uniformly mixing to prepare the fiber recycled roller compacted concrete. According to the composite material prepared by the method, recycling and large-scale utilization of the recycled concrete can be realized, and the service life of projects such as roads and terraces can be effectively prolonged.
本发明公开了一种高低弹模混杂纤维再生碾压混凝土的制作工艺，包括以下步骤：步骤1，将水泥、低弹性模量纤维、高弹性模量纤维、高效减水剂和粉煤灰拌合均匀；步骤2，将步骤1的混合物中加入混凝土拌合用水，搅拌制作出水泥浆体；步骤3，将步骤2的水泥浆体中加入砂并拌合均匀，制作出水泥砂浆浆体；步骤4，将步骤3的水泥砂浆浆体中加入碾压再生粗骨料并拌合均匀，制作出纤维再生碾压混凝土。本发明采用该方法制备的复合材料，能够实现再生混凝土的资源化和规模化利用，有效延长道路、地坪等工程的使用寿命。
