Rice hull ash modified rubber concrete and preparation method thereof
The invention relates to rice hull ash modified rubber concrete which is prepared from the following raw materials in parts by weight: 154-192 parts of cement, 520 parts of coarse aggregate, 154-192 parts of fine aggregate, 3.8-15.1 parts of rubber particles, 9.6-38.4 parts of rice hull ash and 96 parts of water. The preparation method of the rice hull ash modified rubber concrete comprises the following steps: cleaning 40-80 mesh rubber particles with water, and drying the rubber particles in a drying oven at 80 DEG C to obtain rubber particles; preparing raw materials according to a weight ratio; putting the weighed cement, coarse aggregate, fine aggregate and rubber particles into a stirring pot, starting a stirrer to stir the materials for 1 min, then adding rice hull ash, and continuously stirring the materials for 1 min until the materials are uniformly mixed; and adding water into the stirring pot, continuously stirring the materials for 3 minutes, pouring the mixture into a mold for pouring molding, and curing the molded product for 28 days to obtain the rice hull ash modified rubber concrete. Compared with rubber concrete, the rice hull ash modified rubber concrete has theadvantages that the compressive strength and breaking strength are greatly improved, the durability is improved, and the rice hull ash modified rubber concrete has remarkable environment-friendly, economic, energy-saving and emission-reducing significance.
本发明涉及一种稻壳灰改性橡胶混凝土，由如下重量份数的各原料组成：水泥154～192份，粗骨料520份，细骨料154～192份，橡胶颗粒3.8～15.1份，稻壳灰9.6～38.4份，水96份。所述稻壳灰改性橡胶混凝土的制备方法为：将40～80目橡胶颗粒用水进行清洗，并置于烘箱80℃干燥后得到橡胶颗粒；按照重量比例准备原料；将称量好的水泥、粗骨料、细骨料和橡胶颗粒投入搅拌锅内，开动搅拌机搅拌1min，然后加入稻壳灰继续搅拌1min至混合均匀；将水加入搅拌锅内继续搅拌3min后，浇筑到模具中浇筑成型，养护28天后，得到稻壳灰改性橡胶混凝土。本发明制备的稻壳灰改性橡胶混凝土抗压强度和抗折强度相比橡胶混凝土有很大提升，耐久性改善，具有显著的环保，经济和节能减排意义。
