Mixed admixture modified permeable recycled concrete and preparation method thereof
The invention provides mixed mineral admixture modified permeable recycled concrete and a preparation method thereof. The concrete is characterized in that per cubic meter of the concrete contains 24-71 kg of fly ash, 15-43 kg of silica fume, 472 kg of cement, 1132 kg of natural coarse aggregate, 485 kg of recycled coarse aggregate, 14 kg of a reinforcing agent, 5 kg of a water reducing agent and 142 kg of water. The mixed mineral admixture modified permeable recycled concrete provided by the invention has excellent water permeability, compressive strength, breaking strength and durability, and also has excellent water absorption, drainage and water purification capabilities. Compared with a traditional pavement, the permeable recycled concrete applied to paving of a concrete pavement has excellent drainage, ventilation, sound absorption, noise reduction and other performances.
本发明提供了一种混杂矿物掺和料改性透水再生混凝土及其制备方法，上述混凝土，其特征在于，每立方米混凝土中含有：粉煤灰24‑71kg、硅灰15‑43kg、水泥472kg、天然粗骨料1132kg，再生粗骨料485kg、增强剂14kg、减水剂5kg、水142kg。本发明提供的混杂矿物掺和料改性透水再生混凝土具有优异的透水性能、抗压强度、抗折强度及耐久性能，而且具备优良的吸水、排水、净水能力。透水再生混凝土在混凝土路面铺设中的应用，与传统的路面相比，具有优良的排水、透气、吸声、降噪等性能。
