Lightweight recycled concrete and preparation process thereof
The invention discloses lightweight recycled concrete and a preparation process thereof, and relates to the field of building materials. The technical key point is that the lightweight recycled concrete comprises the following components in parts by weight: 180-200 parts of water, 310-340 parts of cement, 760-850 parts of recycled aggregate, and 810-870 parts of gravel aggregate, 35-45 parts of steel fiber, 35-45 parts of a composite ceramic fiber heat conduction material, 45-50 parts of water-absorbent resin, 45-50 parts of waste textile fiber, 5-8 parts of an air entraining agent, and 4.5-5parts of a water reducing agent. The recycled aggregate comprises (by weight): 680 to 750 parts of slag ceramsite, 55 to 65 parts of fly ash and 25 to 35 parts of waste concrete blocks. The gravel aggregate is prepared from the following components in parts by weight: 780 to 830 parts of river sand and 30 to 40 parts of iron ore. The concrete has the effects of increasing the heat conductivity coefficient and improving water seepage, and has the advantages of increasing the contact area between water and the concrete, increasing the drying speed and reducing accumulated water on the road surface.
本发明公开了一种轻质再生混凝土及其制备工艺，涉及建筑材料领域。其技术要点是一种轻质再生混凝土，按重量份数计，包括以下组分：水180‑200份；水泥310‑340份；再生集料760‑850份，所述再生集料包括680‑750份的炉渣陶粒、55‑65份的粉煤灰和25‑35份的废混凝土块；砂石集料810‑870份，所述砂石集料包括780‑830份的河砂和30‑40份的铁矿砂；钢纤维35‑45份；复合陶瓷纤维导热材料35‑45份；吸水树脂45‑50份；废旧纺织纤维45‑50份；引气剂5‑8份；减水剂4.5‑5份。本发明的混凝土具有增加导热系数、提高渗水的效果，并且具有增加水分与混凝土的接触面积，提升烘干速度，从而减少路面积水的优点。
