Construction waste recycled aggregate applied to road base mixture and preparation method of construction waste recycled aggregate applied to road base mixture
The invention discloses a road base mixture using construction waste recycled aggregate, which comprises construction waste mixed aggregate, cement, an anti-shrinkage stabilizer and water, the mass ratio of the construction waste mixed aggregate to the anti-shrinkage stabilizer to the cement is 100: (4-8): (4-6), the construction waste mixed aggregate is composed of crushed concrete aggregate and crushed brick aggregate, and the crushed brick aggregate is composed of crushed concrete aggregate and crushed brick aggregate. The mass ratio of the crushed concrete aggregate to the crushed brick aggregate is (0.5-3.5): 1, and the maximum nominal particle size of the crushed brick aggregate is not greater than 9.5 mm; the anti-shrinkage stabilizer is composed of modified polypropylene fibers, titanium gypsum, a water glass-based exciting agent and steel slag, and the mass ratio of the modified polypropylene fibers to the titanium gypsum to the water glass-based exciting agent to the steel slag is (0.4-0.6): (28-32): (13-17): (83-87). The heat-conducting and flame-retardant properties are realized.
本发明公开了建筑垃圾再生骨料用于道路基层混合料，包括建筑垃圾混合骨料，水泥、抗收缩稳定剂和水，建筑垃圾混合骨料、抗收缩稳定剂和水泥的质量比100:4‑8:4‑6，建筑垃圾混合骨料由破碎混凝土骨料、破碎砖块骨料组成，破碎混凝土骨料、破碎砖块骨料的质量比为0.5‑3.5:1，破碎砖块骨料的最大公称粒径不大于9.5mm；抗收缩稳定剂由改性聚丙烯纤维、钛石膏、水玻璃基激发剂和钢渣组成，改性聚丙烯纤维、钛石膏、水玻璃基激发剂和钢渣的质量比为0.4‑0.6:28‑32:13‑17:83‑87，本发明具有优良的导热和阻燃性能，从而使得由该改性聚丙烯纤维制备的道路基层混合料，具有的导热阻燃性能。
