Example Embodiment
[0017] Specific embodiment 1: This embodiment provides a plant fiber recycled concrete block, the specific content is as follows:
[0018] 1. Design requirements of mix ratio
[0019] The mix ratio design should meet the "Design Regulations for Recycled Concrete Structures":
[0020] 1. Recycled concrete should be calculated by weight method.
[0021] 2. The total water consumption of recycled concrete is the sum of net water consumption and additional water consumption. When pre-wet treatment is used for recycled coarse aggregate, additional water consumption may not be considered.
[0022] 3. The determination of the net water consumption should be based on the slump and the maximum particle size of coarse aggregate, and the reference water consumption per unit volume of concrete should be increased by 5% according to JGJ5 of the "General Concrete Mixture Design Regulations".
[0023] 4. The additional water consumption should be determined according to the water absorption rate of the r
Example Embodiment
[0034] Specific embodiment two: This embodiment is different from specific embodiment one in that the ratio of recycled crushed stone to coarse aggregate is 50wt%, and the mass percentage of plant fiber (that is, the mass percentage of concrete block) is 2wt%.
[0035] The strength test was carried out on concrete test blocks without plant fiber and recycled aggregates and plant fiber recycled concrete blocks. The test mix ratio is C50 mix ratio. Due to the limitation of the experiment time, all test blocks were subjected to strength testing after seven days of ordinary curing, and then the 28-day strength was calculated according to the empirical formula.
[0036] The 7-day strength of ordinary concrete blocks without recycled aggregates and plant fibers is 36MPa, 37MPa, and 41.5MPa. According to the empirical formula, the strength of the block is proportional to the logarithm of the age, and it reaches the C50 strength after calculation.
