Concrete solid brick and preparation method thereof
The invention relates to the technical field of solid bricks, in particular to a concrete solid brick and a preparation method thereof, the concrete solid brick comprises the following raw materials: clear fine sand, fly ash, cement, pebbles, a water reducing agent, cellulose and pebbles, the fly ash comprises 28-32% of coarse ash, 20-25% of medium ash and 10-15% of fine ash; the particle size of the fly ash is less than 0.3 mm, the ignition loss is less than 10%, the active SiO2 is greater than 50%, the SO3 is less than 3%, and the silt content is less than 1%; according to the present invention, the concrete solid brick uses fly ash, cement and gravel as the main raw materials, contains active SiO2, has characteristics of volcanic ash effect and potential hydraulicity, can be hydrated to generate hydrated calcium silicate gel, can reduce the use amount of the cementing material, has characteristics of simple production process, no need of a large amount of mechanical equipment, no need of a kiln, no need of coal burning, and environmental protection. Clay is not used, capital, energy and cultivated land can be saved, fly ash is wide in source, low in price and convenient to use, product cost can be reduced, and economic benefits can be improved.
本发明涉及实心砖技术领域，具体为一种混凝土实心砖及其制备方法，包括以下原料：清水细砂、粉煤灰、水泥、小卵石、减水剂、纤维素和小石子，通过粉煤灰粒径分别为：粗灰28～32％，中灰20～25％，细灰10～15％；粉煤灰粒径小于0.3mm，烧失量小于10％，活性SiO2大于50％，SO3小于3％，含泥量小于1％；能够使实心砖的砖体强度和耐久性较高，通过混凝土实心砖，是以粉煤灰、水泥、砂石为主要原材料，含活性SiO2具有火山灰作用和潜在水硬性，能水化生成水化硅酸钙凝胶，可减少胶凝材料用量，生产工艺简单，不需大量机械设备，不需窑炉不烧煤，不用粘土，可节约资本、能源、耕地，粉煤灰来源广，价格便宜，使用方便，可降低产品成本，提高经济效益。
