Environment-friendly energy-saving composite sintered brick and preparation process thereof
The invention relates to the technical field of building materials, in particular to an environment-friendly and energy-saving composite sintered brick and a preparation process, and the raw materials for preparing the sintered brick comprise the following components based on 100 wt%: 25-30 wt% of stone powder mud, 40-45 wt% of sand washing mud, 12-15 wt% of basic soil and brick slag, and 10-20 wt% of coal ash and pebble coal. Wherein the calorific value of the coal ash and the calorific value of the pebble coal are 250-280 calories/kg and the like. According to the invention, industrial wastes are used as main raw materials, so that resource utilization of the wastes is realized, and environmental pollution is reduced; the coal ash and pebble coal are used as fuels in the sintering process, and the calorific values of the coal ash and pebble coal are controlled within the range of 250-280 calories/kg, so that the combustion requirement of a kiln at 900-1000 DEG C is better met, and more efficient energy utilization and environmental protection performance are realized.
本发明涉及建筑材料技术领域，更具体的是涉及一种环保节能型复合烧结砖及制备工艺，制成所述烧结砖的原料以100重量％为基准由下列成分组成：25‑30wt%石粉泥、40‑45wt%洗沙泥、基础土及砖渣共12‑15wt%、以及煤灰和石子煤共10‑20wt%；其中，煤灰和石子煤的热值共为250‑280卡/千克等。本发明以工业废弃物为主要原料，实现了废弃物的资源化利用，减少了环境污染；本发明烧结过程中利用煤灰和石子煤作为燃料，且将煤灰和石子煤的热值控制在250‑280卡/千克的范围内，更好地适应窑炉900‑1000摄氏度下的燃烧需求，并实现更高效的能源利用和环保性能。
