Modified concrete and large-span floor slab
The invention provides modified concrete and a large-span floor slab which are novel in structural design. The modified concrete is prepared from the following materials in parts by weight: 20-50 parts of limestone, 15-30 parts of clay, 30-40 parts of iron ore, 10-20 parts of coal cinder, 25-40 parts of gypsum, 20-40 parts of sand, 50-80 parts of pebbles, 30-40 parts of a high-molecular polymer, 2-6 parts of a modifier, 5-8 parts of an enhancer and the balance of water. The modified concrete is processed by the following steps that S1, raw materials are prepared, specifically, 20-50 parts of limestone, 15-30 parts of clay, 30-40 parts of iron ore and 10-20 parts of coal cinder are taken and smashed through a crushing machine, and then a smashed mixture is subjected to ball milling through a ball mill to prepare a raw material; and S2, calcining is conducted, specifically, the raw material in the S1 is put into a cyclone separator for preheating. According to the modified concrete, the high-molecular polymer is added into the concrete raw material, so that the structural performance of a floor slab manufactured after the concrete is solidified is enhanced, good anti-seismic and anti-sedimentation effects are achieved, the service life of the floor slab is prolonged, and then the disaster resistance of a building is improved.
本发明提供一种结构设计新颖的改性混凝土及大跨度楼板；包括以下材料，按重量份计：石灰石20‑50份、粘土15‑30份、铁矿石30‑40份、煤渣10‑20份、石膏25‑40份、砂子20‑40份、石子50‑80份、高分子聚合物30‑40份、改良剂2‑6份、强化剂5‑8份、其余为水，改性混凝土包括以下步骤加工而成：S1.制备原料，取石灰石20‑50份、粘土15‑30份、铁矿石30‑40份、煤渣10‑20份并采用破碎机进行分别粉碎，然后将粉碎后的混合料采用球磨机进行球磨制成生料；S2.煅烧，将S1中生料放入旋风分离器进行预热。本设计利用在混凝土原料中加入高分子聚合物，使得混凝土凝固后制成楼板的结构性能增强，具有良好的抗震，抗沉降的效果，使得楼板的使用寿命得到延长，进而使得建筑的抗灾害能力得到提升。
